RFID Highlights from the GS1 Connect 2018 – Cut Chargebacks and Delight the Consumer

Jun 08, 2018

中文版 Chinese version

Roughly 1,000 attendees headed to Phoenix, Arizona this year for the GS1 Connect conference. The JW Marriot Desert Ridge provided a convenient and relaxed environment where retailers, suppliers and solution providers mingled for three days. I attended a number of sessions on the conference program and here are my highlights from select speakers.

GS1 USA: RFID Is Not a Retailer Story, but More a Supply Chain Story

The theme of the whole Connect 2018 “Accelerate” refers to the universal demand to react on customer demands faster and faster. As Dr. Brian Gibson of the Auburn University put it in his presentation: the traditional “fast or free” is today understood by consumers as “fast and free”. This obviously inflicts extreme performance, efficiency and accuracy requirements on the supply chains.

As I look at this from the RFID perspective, GS1 is doing a good job in driving the RFID adoption. At the AGM Initiative Open Meeting Mr. Patrick Javick explained that technology adoption is currently facilitated in a peer-to-peer format to openly address the issues between the trading partners – underlining the fact that the benefits of RFID are essentially spread throughout the supply chain.

This also raises the question of data ownership and sharing. In his key note Mr. Bob Carpenter, the President and CEO of GS1 USA, explained how everything will be connected, and how for businesses protecting the product identity is equally important as protecting our personal identity.

Mr. Bob Carpenter envisioned also that GDPR will come to the USA soon

Herman Kay: RFID Makes Us a Better Supplier

Mr. Richard Haig of Herman Kay Company, Mr. Bill Connell of Macy’s and Mr. Coby Sparks of J. Reneé Company joined forces to talk about the 10 ways to reduce friction in the supply chain.

From the Supplier point of view the RFID enabled improvements in Shipping Accuracy are substantial. Mr. Haig summarized that the utilization of RFID in outbound shipment validation makes Herman Kay a better supplier for their customers. The way I’m hearing this is that the better Supplier enjoys more business – and less chargebacks.

Macy’s Is Leveraging Their Superior RFID Tagging Coverage

Macy’s has been a beacon-like forerunner in building and eventually enjoying the benefits of shop floor inventory accuracy based on RFID. They have 100% RFID coverage of merchandise from their private brands, as well as 73% of vendor brands. According to Mr. Connell Macy’s is already gearing towards to enhance Omni-Channel Fulfillment even more, and there will be enhanced personalized experience to delight the consumers in the future.

In a separate session Mrs. Pam Sweeney explained how Asset Protection is a domain that the RFID-based data is currently dramatically reshaping. There is a vast pool of added value leverage in core business processes that Macy’s is additionally looking to address, such as financial inventory.

Dillard’s Found DC Inbound Process Gaining Efficiencies

According to Mr. Chuck Lasley, the Director of Application Development, Dillard’s is seeing quantified benefits by utilizing a tunnel reader in one of their distribution centers. The tunnel verifies inbound shipment content against Advance Shipment Notice (ASN). Only packages that don’t show the expected content are routed to manual audit.

Mrs. Sweeney, Mr. Lasley and Mr. Javick around the next-level retail RFID use cases

The RFID based inbound process is shown to be 3-4 times faster than the old manual process! Impressed of this pilot result and generally motivated by the experiences of other retailers, Dillard’s currently says they’re going to be mandating RFID tagging on first product categories within the next 18 months.

Project Zipper Quantifies Immediate Business Value for Suppliers Especially

The Auburn University RFID Lab is collaborating with selected retailers and suppliers in the Project Zipper. As Mr. Justin Patton, the ARC Lab Director, explained, the project participants share their UPC barcode and EPC RFID data on shipments across the supply chain. The data streams are then analysed to find and understand discrepancies.

The Project Zipper 1st phase report will be published soon, but the early results already show that there is a lot in the supply chains that will change as trading partners shift focus from SKU quantities to item level tracking. As the project findings are confirmed and data sharing across supply chains improved accordingly, one frequent discussion topic that many anticipate to fundamentally change tones is chargebacks.

NXP Perspective: RFID Will Be an Integral Part of the Product

Mr. Nigel Stott spoke about NXP’s consumer driven approach on RFID, where RFID-enabled items bring convenience to shopping. Mobile checkouts at the shelf removes the need to line up for the checkout counters: Grab – Tap – Go! Sounds great, and is so for the retailer too, because in NXP’s view the in-store mobile payment ensures 100% engagement in loyalty programs.

Mr. Stott also mentioned sustainability. As the tag will be an integral part of the retail item, the tag life time will be the same as the product life time. This opens up a whole new range of possibilities for more intelligent home appliances, such as washing machines. I’m thinking further to producer liability, recycling and circular economy, which is a rising priority on the European side of the Atlantic.

Words of Wisdom

As a Finn I was suprised and delighted during the day 3 as Dr. Tricia Wang quoted the former EU Commissioner Erkki Liikanen while talking about “Winning the Data Revolution”.

RAIN RFID Maturing, BLE on the Rise – Report from RFID Journal Live! 2018

Apr 14, 2018

I have been going to the biggest RFID shows for 12 years now. In 2007, it was RFID World in Grapevine, TX. And for the last ten years, it has been RFID Journal Live!. Once again, I flew to Orlando to find out what is new and exciting in RFID. And I have to conclude that not much. Which is pretty much what I also said last year.

RAIN RFID Industry Maturity

But while nothing new might be bad for RFID Journal Live!, it is not necessarily bad for the RFID industry. It may be just a sign of maturing. The development of an industry is often described with the industry maturity S-curve, which could look something like the one below for RAIN RFID. All the market data suggests that the RAIN RFID market is growing fast, so I would assume that we are currently in the growth stage.

RAIN RFID industry maturity curve

What is typical of the growth stage, compared to the earlier embryonic stage, is that the industry is more focused on process innovation than on product innovation. As a result, we are not really seeing new game-changing products. Rather the technology companies are working hard in producing the existing ones more efficiently, which should eventually lead to lower costs which further supports market growth. And there were some signs of that at the show. First of all, many technology providers were talking about growing volumes, and investing in manufacturing equipment. And on the supply side, BW Papersystems launched a new chip bonding machine that could improve manufacturing capacity.

We are seeing the same trend at Voyantic as well. While at the beginning of the decade, technology providers were in the need of tools for designing tags, the focus has shifted into production testing equipment. And Voyantic’s latest launch of the Reelsurance Pro for RAIN RFID and NFC testing and encoding follows the same trend, improving the efficiency of the manufacturing process.

But There Was Something New After All

Even if we are further along the maturity curve with most RFID technologies, new S-curves will continue to arise. Secure RAIN RFID according Gen2V2 is evolving, and EM Microelectronic has launched new ICs that present a significant advancement in that field. I feel this market is still in the embryonic stage, and there is a lot to do in building up the market.

But above all, what surprised me was that Bluetooth Low Energy (BLE) has made its way into the product portfolios of many traditional RFID tag manufacturers. And to top it off, HID Global even won the Best New Product Award with its Bluetooth sensor beacon. I guess it is a matter of opinion, whether you want to call BLE RFID. But it is definitely a related technology. Maybe we need to stop positioning the different technologies against each other and accepting that we need different technologies for different applications – all providing a gateway to the Internet of Things.

Connections Summit Brings RAIN RFID, NFC, and AIDC Together

Mar 09, 2018

中文版 Chinese version

Until now, it has seemed that different RFID and AIDC technologies, as well as the organizations that represent them have resided in their own silos. Both RAIN RFID and NFC have been focusing on their own applications and they don’t seem to have much in common. At the same time, both technologies have been quite distant from all the discussion surrounding the Internet of Things (IoT).

But as a matter of fact, the two technologies have a common goal: they strive to be means for connecting items to the cloud. And the technologies don’t really compete against each other. So, it makes perfect sense that the two industries started to pull into one direction. That is why the RAIN RFID Alliance, the NFC Forum and AIM Global joined forces to arrange the first Connections Summit at the Google campus in Sunnyvale, California.

Connections Summit 2018 Attracted Excellent Attendance

The Connections Summit brought together the RAIN RFID and NFC communities, as well as a lot of curious visitors, into a day full of presentations and panels that covered various aspects of these technologies. Overall, there were over 450 people participating, which I think is a huge success. The presentations covered the host Google’s view of the IoT, IDTechEx’s market information, and numerous case studies highlighting the use of both NFC and RAIN RFID. It was clear that RAIN RFID, NFC, BLE (Bluetooth Low-Energy) and other wireless technologies, as well as optical codes have their own benefits and uses. There are some overlaps, but the overlapping application areas are shadowed by unique benefits of each technology.

Intranets of Things is not True IoT

Even if each data collecting technology has its own benefits, there are also shared development needs in the broader identification and IoT industry. In many presentations and discussions, the questions related to the collected data. There is a clear need for common standards on how to point the ID codes to actual data in the cloud (the digital twin). Currently, each technology relies on different methods and standards, and in many cases, applications are company-specific. The current Internet of Things (IoT) is actually a number of separate intranets of things, offering very little meaningful IoT data available “in the internet”.

Data Sharing Requires Determining of Ownership and Privacy

In order to move from the intranets to real IoT, data sharing standards are needed. The topic is complicated: In addition to pure standardization, also questions of privacy and data ownership have to be addressed. What part of the data is owned by the owner of the item? What is owned by the organization collecting the data? And who owns the data that is aggregated from multiple sources? The discussion has started, but the IoT industry has a long road ahead before all these questions are solved.

So, what is the verdict? Did the event work out? Yes! There was definitely a need for this kind of cross-pollination. Everyone I talked to at the event emphasized that they had learned a lot. I am sure that this event was not the last of its kind, I am looking forward to the next one.

RAIN Man’s Letter to Santa, 2017

Dec 23, 2017

Dear Santa,

I saw you at the shopping mall just the other day but you were occupied with other business, so I left you alone. I’ll give you ten points for the impressive entourage!

How has year 2017 been for you? Good funnel and outlook for 2018, or is that still too far away to say?

Me? Thanks, family is good, the dog and the house as well. However, as the next year is again just around the corner, I really wanted to write you this letter from the RAIN man’s perspective.

Please Help Retain the Talents

Both in your organization and ours it’s only natural that people come and go. I mean, it must be hard for your little helpers to keep those huge inventories accurate and muscle around all the odd-shaped packages, such as pianos and snowmobiles! Some of them surely get tired and steer their careers towards less seasonal operations. It’s the same at our end, with the difference ours is a little less seasonal and our helpers are taller than yours. The mileage is rough for both.

Talent pool in the RAIN business is still scarce, and it takes time to train the new superheroes. With that said, as we both need to keep our operations efficient and scalable, I would very much hope for two things:

  1. Keep the best talent motivated, committed and in-house
  2. Endorse standard procedures (or de-facto standard, as your chimney entrance)

Please Just Give Us One Name to Work With

Radio Frequency Identification went by the name RFID for a long while, but it seems we’ve run out of space under the same umbrella with so many very different technologies: LF, HF and UHF. First came NFC Forum and rebranded a hefty part of the portfolio. After a while RAIN Alliance was established to nurture UHF RFID under a new brand, RAIN. However, not all the stakeholders got onboard the RAIN train, which means plenty of branding confusion especially in the retail-domain, where EPC numbering brand by GS1 further complicates communication.

Please, let there be light, co-operation and goodwill among all the stakeholders, and show them the way. We saw GS1 and RAIN shake hands already in Lille in February 2017, they should just get the puzzle finally completed:

Please Supply RAIN Smartphones for Teenagers

Many seasoned RAIN-believers start to attract shades of gray at their temples. I’ve recently been told I’m among them. It’s not that we wouldn’t be as bright and innovative as always, but the youngsters think and act differently.
I’d like to see teenagers inject some craziness into our industry.

After a decade of waiting, could you finally come up with a reasonably priced RAIN enabled smartphone with fair battery capacity that we could give for them? Good things would happen. And I want one, too!

Please do not brand the phone “tubular”.

Please Show E=mc2 for RAIN

On the component level, after a decade of hard work, we have the basic performance metrics for both RAIN tagged items (TIPP) and readers (reader sensitivity testing). Please show everybody how the system level performance can be reasonably estimated based on those performance metrics! I mean the environment is a difficult variable, but on your discretion, just define a new variable , like you gave the speed of light “c” for Albert Einstein.

That’s all! Travel safe, protect yourself against frostbites and watch out for those house-securing-bulldogs. Stay hydrated as well – I know the costume doesn’t ventilate too well.

What Do Babies and RFID Have in Common?

Sep 26, 2017

Something worried me before my first daughter’s arrival, something I had been already warned: “Babies are born without a handbook”. I am used to working with procedures, methodologies or at least to have some standards to follow; and now I was going to face the most demanding challenge in my life without any kind of guidance.

But, I gradually noticed that it was not going to be that way, and that the parallelism between the technology I have been working with for more than 15 years, RFID ― those intelligent chips enabling the Internet of Things which we can find in more and more stores and warehouses every day ―, was clear from minute zero. Many companies, end users and system integrators think, like I did in early stage, that there are no rules nor guidelines for a project to become successful, but that trial and error is the only way to gain experience to face it with. Is that how I should bring my daughter up, by trial and error?

Look for Help – It Is Available!

As with RFID, when Carlota was born, tranquility came by being surrounded by experts in the field, and not just sympathizers who have faced that same situation. Firstly, I was provided with a handbook. Seriously! Guidelines about what to do in certain situations, such as tips to interpret the baby’s cries. Better than improvising with the newborn, right? Likewise, the handbook suggested the baby to sleep on her back, while just a few years ago it was suggested to sleep on her stomach.

Having professionals, who advise us following the latest recommendations and standards, gives us the peace of mind to do things well in RFID, too.

For example, some years ago it was always recommended to do pilot tests before deploying an RFID project, but then we realized that the results were conditioned by the selected reader and selected tags. Yes, it seems obvious, but before even starting those pilot tests, readers and tags had already been chosen within the wide spectrum of combinations existing in the market. Doesn’t it make sense to first know what we need before choosing them? For this reason, nowadays professional RFID companies use standards (have you heard about the TIPP methodology by GS1?) and laboratory equipment capable of determining which RFID readers and tags in the market will give better results in a real test.

To Do Comparison You Need a Reference

Carlota was weighed, her length was measured, the diameter of her head was measured… these were going to be the indicators that would tell us if her growth was adequate or not. It is not useful to keep trying things; we must measure, measure Carlota and RFID, and do it with the right tools. But not only that! What a surprise when the kilograms and centimetres at the hospital were not the same kilograms and centimetres at the drugstore, not even the same as those at the pediatrician. How should I decide if everything is okay or not when one tool tells me “yes” and another “no”?

And I remembered so many customers I have who do not worry about calibrating their RFID measuring equipment, and a tag that could work with any reader when tested with a given equipment, but the same tag that would only work with the most powerful and sensitive readers when tested with other equipment.

Define Your Requirements Before Selecting the Solution

I have always insisted on my clients that they should not choose the best tag, but the most appropriate tag for their application; with my daughter this situation happens from diapers to milk, but not only with her milk, also with the adults’ milk! What kind of milk do you have in your fridge? The one with more calcium, vitamins, etc. on the market; the cheapest one; or the one you consider good enough for you and your family? The same thing happens with RFID tags, where it makes no sense to pay more for the best tag on the market, because there is no such ideal tag, but the one that is the best one for your application, the best milk for you.

Regarding prices, what should we think of the cheapest ones? Again, if their quality and features are the most convenient for us, they are definitely the best choice. Please pay attention to both concepts: good quality and minimum required features.

And what about the quality? I do not mean good finishes or performance … but that once a model is chosen, every diaper, every tag, always perform the same way; their features do not vary among them and they have a certain margin of operation. It seems obvious, but the cheapest tags on the market are usually cheap because although they all work (i.e. a standard RFID reader can detect them), not all of them perform the same way; some tags can be detected at much longer distance than others, even though being the same model. I checked it when I bought some cheaper diapers than the usual ones, which seemed to absorb as much as the best ones, but it was not always like that, whether it was a discreet pee or a champion one.

“Always” is an interesting and challenging concept, but at least we need to be prepared before the chosen diaper stops performing as expected and what would be acceptable. What if a customer makes the wrong choice and purchases 5 million reusable tags regardless of their operating margin? They could perform well today, and at the slightest change in the initial conditions of use, stop doing so.

Select Suppliers That You Can Trust

Finally, once the feeding bottles, diapers, milk were chosen, and their brands, prices and features were evaluated, we had to decide where to buy such an amount of supplies. I have to admit that we started buying some stuff online and taking advantage of promotions at the hypermarket, but it all depends on how seriously we want to get involved in bringing our daughter up. Right now, there are many things we decided to buy in pharmacies and specialized stores, not only for the qualified professionals who helped us from the beginning, but also for the access they have given us to brand events, training, samples of new products…

In the end, we are learning day by day. Carlota relies on us, and we rely on professionals and industry standards, because there is a reference for every industry. If in children’s upbringing references are driven by the WHO, which are followed by pediatricians; in RFID industry the guidelines are given by ISO, GS1 and RAIN RFID Alliance, and there are more and more system integrators and end users who, by following them, have stopped suffering with the deployment and adoption, respectively, of the technology. Why should we suffer as the result of improvising with our newborn instead of enjoying her growth without worries?

Welcome, Carlota.
RFID, it’s your time.

Using Tagging Performance Specifications to Secure 100% Readability of RFID Enabled Tires

Aug 17, 2017

中文版 Chinese version

Identification of tires has been one of the early use cases of RAIN RFID already back in 2005. It took almost ten years for the technology and value chain to mature to a state when this extremely challenging application became finally possible.

Million Reasons to Tag Tires

There are countless ways to utilize RFID enabled tires. Early deployments follow the use cases familiar in the generic retail business: improving the traceability in the supply chain and raising efficiency in warehouse inventory and management. Over time I bet we will also see use cases after distribution, such as tire fleet management, safety monitoring (pressure, wear, retreading), and eventually even in recycling.

Once tires are RFID enabled, it opens enormous possibilities for companies to streamline processes and even create new business models.

“Scrapping a Finished Tyre is Not an Option”

If an embedded RFID tag is defected, it cannot be replaced with a new one because of safety and practical reasons. At the same time, no manufacturer is willing to scrap a new baked tire because of a non-functional RFID tag. Is there a way to avoid such a situation?

A carefully implemented quality monitoring helps keep the tire manufacturing process lean and efficient. RFID is implemented in various ways within the tire industry. Thus, preparing the tagging specifications according to actual use cases of the complete value chain is a prerequisite. Read more of this framework:

What is the Framework of RFID Tagging in Tire Industry?

Learn how to prepare tagging specifications according to actual use cases of the complete value chain!

Embedding RFID UHF Tag into Rubber and RF Testing

Before embedding in rubber, the tire tags are tested in free-air conditions. UHF tire tags are typically over tuned to frequencies over 1 GHz. This makes RF testing a challenge because standard RFID readers operate at frequencies below 1 GHz.

Sensitivity of RAIN RFID UHF tag in different situations. The lower the graph, the higher the sensitivity and thus longer the read range.

From the manufacturing standpoint, additional requirements include:

  1. individual tag test should be wireless;
  2. test may be performed on trays with a large number of other tags in close proximity;
  3. the production flow cannot be slowed down.

The Voyantic solution is to utilize Tagsurance RFID tester together with the Snoop Pro near field coupling element. This enables accurate READ sensitivity tests for the complete dipole tag structure with excellent correlation to far-field performance.

RF testing used to be one of the bottlenecks in the tire tag production process. However, the sophisticated test features of the Tagsurance tester mean that the slowest processes are the mechanical ones.

Please read of our testing solution in more detail from our customer case study Michelin – Tire Tags with Consistent Quality!

Industry-Wide ISO Standards in the Horizon

The industry is currently waiting for the work group to finalize following standards, like

For an update on the ISO standards process, please stay tuned for an upcoming blog from Juho Partanen later this year.

If you’d like to hear how Voyantic can enable you to perform tire RFID testing in your facility, just drop us a line – it will be my pleasure to walk you through the process!

The Evolution of RAIN RFID Testing Started with Inlays, and Ends with…

Jul 07, 2017

中文版 Chinese version

Evolution of organisms is one broadly accepted theory. Let me walk you through the phases evolution has taken when it comes to RAIN RFID tag testing.

Starting Point: The RFID Inlay

In the end of 90s there were no off-the-shelf solutions to start doing RFID research and tag testing. Hence the classical Radar Cross-section (RCS) seemed like a great way to characterize the UHF antenna of an inlay. It’s just that such a passive antenna test didn’t enable designers even to optimize the forward link: matching the impedance of IC with the impedance of the antenna. As a result, it was a struggle to get the tag tuning right. Additionally, the RCS measurement told nothing of the read range that the inlay design can deliver.

Delta Radar Cross-section (deltaRCS) was a serious step in the right direction for two reasons: the impedance match could be better analyzed and the fundamental reverse link parameters were brought into consideration. Read ranges started to improve. Around 2005-2007 also the first commercial tag test systems became available. Those systems, such as the Tag Analyzer from SAVR Communications, the Voyantic Tagformance and MeETS from CISC, already utilized the Class 1 Gen2 protocol to better grasp the actual performance of an RFID inlay. Pavel Nikitin’s paper from 2012 explains the theory and practicalities of diverse test systems in detail.

As tag prototypes were made and production samples tested, many companies focused mainly on the inlay performance in free air conditions. It didn’t take long for the first experts to realize that the test results better correlated with the real-world use case performance when the inlays were attached on various materials prior to testing. So, approaching the current decade it seemed half of the industry was busy working with various reference material sets, and the other half with aluminum plates of various sizes.

Era of Testing Tags on Items

To bring more sense into real-world performance of inlays, Voyantic introduced the Application Development Suite already in 2008. With the Population Analysis function anyone could visualize and study the behaviour and properties of tags in groups. As we have later learned, very few did such analysis before 2011, which manifests two related findings:

  1. The more groundbreaking the concept, the longer time it takes to really sink in
  2. It takes a lengthy period of time for engineers to learn how to explain certain groundbreaking concepts in an understandable way.

Tag-to-tag close coupling effects are indeed complex, and only partially understood and explained by the academic community even today. As a kind of workaround, the ARC Program emerged in 2011 to combine exhaustive label testing with data collection from actual RAIN use cases in retail. Outcome of that analysis are the ARC performance categories and the related certified inlay lists.

These ARC inlay lists simplified tag selection for the US retailers. I’d also state that the success of the ARC program pushed the technology vendors to seek additional ways to ease the adoption of RAIN RFID technology by collaboration. It can be said that the Program may have slowed down the market entry time for new inlay types and vendors obviously because they needed to pay and wait for certification tests before getting on those lists.

On the positive side waiting pays off, because the ARC inlays lists are one functional way for a new vendor to gain access to the US retail deployments.

Early this decade the performance testing elsewhere in the RFID ecosystem already focused on tags on actual items. However, the industry lacked a documented and open framework to correlate various test setups with each other. This void, together with the industry’s quest to improve the scalability of deployments, led to VILRI’s tagged item prototype project. Eventually that project gave birth to the Tagged Item Performance Protocol, aka TIPP, in 2015.

TIPP is a standard-like guideline from GS1 that establishes and combines three fundamental aspects:

  • Key performance metrics for RAIN enabled items
  • Test methodology that anyone can repeatedly use to extract these metrics
  • Performance grades for individual and stacked items.

Among its other benefits, the open and thoroughly documented TIPP guideline enables anyone to easily communicate their tagging requirements without sharing details of their processes and use cases.

Following the TIPP approach tagging solution providers are free to innovate and offer their latest products and solutions immediately without the need to have them certified by third parties.

How Would You Like Your RAIN Enabled Items? Separate, Boxed, Stacked, Hanging…

Close coupled RAIN enabled sporting goods

In the fall of 2017 an update to TIPP introduces a new test protocol for dense hanging stacks. This test protocol puts 100% reads of all the items to the focus, and thus leaves the close coupling effect purely for tagging experts to handle and solve. I anticipate that RAIN deployments especially around sporting goods retail will benefit from this new test protocol.

RAIN Read Performance Requires Input Also From the Reader Side

Albeit the tag side already enjoys highly sophisticated performance test framework, there are still a few missing pieces on the RAIN reader side. The Reader Sensitivity Test Recommendation from the RAIN Alliance was a grand milestone already. The dialogue and evolution would greatly speed up if the industry stakeholders, such as GS1 and RAIN Alliance, would take initiative to derive meaningful open performance metrics for read zones and readers in general.

That’s my evolution story for now. And no, the evolution of RAIN tag testing has not stalled, instead it’s constantly looking for new paths to make RAIN technology spread more efficiently. That’s also where Voyantic keeps on investing in. Your feedback on these thoughts will be greatly appreciated!

When Buying Tags – Ask the Right Questions

Jun 16, 2017

中文版 Chinese version

I frequently lecture in RFID training events, and now and then, a question comes up from RFID users and system integrators: “When buying RAIN RFID tags, what should we ask from suppliers, and what should we tell the potential supplier?”. I asked the same question from some RFID tag manufacturers and spiced the answers up with my own experiences and collected the following summary from the answers.

How to Get a Good Quotation for RFID Tags

Plenty of information is related to the tag selection. The more information that can be given to the tag supplier, the easier it is for them to propose a good tag. And the better questions you ask, the better answers you get, and the easier it is to make an educated decision. At the same time, it is essential to keep the focus – what is important for the project at hand and what can be left out.

The issues to consider and communicate are in the following areas:

  • Use case – what can I tell about the tag use
  • Tag functionality
  • Tag format, shape and size
  • Durability requirements
  • Performance requirements
  • Delivery format and quantities
  • Printing and encoding needs
  • Quality data
  • Delivery terms and pricing
  • Change management
  • Additional services from the supplier

There are plenty of questions under each of these areas. Download our free RAIN RFID tag buyer’s guide to get a more comprehensive understanding and an example request for a quotation!

RFID Journal Live in Phoenix – The New Exciting Stuff Was in IEEE RFID

Jun 02, 2017

中文版 Chinese version

This year’s RFID Journal Live! was arranged in Phoenix, AZ three weeks ago. I have been scanning through different reports about the show, and they all seem to amplify my own perception: the overall business was good, things are moving forward, but there was nothing particularly new and exciting this time. Sure, the inventory robots were still there, readers are integrating with antennas, and some new chips were announced, but that’s about it.

So, instead of writing about Journal Live!, this year I am focusing my show report on a co-located event that always delivers something new, the IEEE RFID conference. The conference was arranged for the 11th time, and I think I have only missed it once – though often I have had to divide my time between IEEE and the trade show.

The conference featured two excellent key-note presentations: Secure RFID for Trusting Devices and Data by René Martinez of Honeywell and Near-Zero Power Radio Frequency Receivers by Troy Olsson of DARPA. And then there were a total of 32 technical papers presented. Most papers were accepted in these categories:

  • Localization
  • Protocols and Security
  • Antennas and Propagation
  • Circuits, Devices and Readers

So, it seems that localization is on the rise, as the category has reached the top from outside the top-5 of 2016 event. I haven’t really seen asset localization properly break through in the industry, but I wouldn’t be surprised if it did in the near future.

Poster Session

During the last few years, IEEE RFID has arranged a poster session in the RFID Journal Live! exhibition area. So, if you do one thing to learn about what is going on in the research space, I recommend browsing through the poster area. In just half an hour you will get a nice overview of the latest research related to circuits, protocols, antennas, chipless sensors, etc. This year, there were a total of 25 posters from universities around the world, but also one from the industry: the French company Primo1D had a poster about their RFID yarn. A full list of poster titles can be found here.

This year, I was privileged to be a member of an expert panel that was assigned to choose the best poster. It took us two hours of looking through the posters, interviewing the presenters, and discussing, until we were able to decide the winner:

“A Dual-Band Wireless Power Transfer and Backscatter Communication Approach for Implantable Neuroprosthetic Devices” by Eleftherios Kampianakis and Apoorva Sharma (University of Washington, USA); Jose Arenas (University of Washington, Chile); Matthew Reynolds (University of Washington, USA).

The presented research combines UHF and HF RFID, as well as many disciplines of electronics and RF engineering into an implantable neuroprosthetic testbed. A more detailed description can be found here.

Best Paper Award

This year’s best paper award went to Pavel Nikitin of Honeywell for his paper titled ‘Self-Reconfigurable RFID Reader Antenna’. The paper presents a method for varying the beam of an antenna. The method is presented with a two-element Yagi antenna, where the parasitic element is loaded with a self-oscillating circuit. The ability to change the reader beam could be especially useful when inventorying static tag populations, e.g. when using an overhead reader to inventory a retail store.

But what pleased me most, was that some of the measurement data in Pavel’s paper was generated with the Voyantic Tagformance Pro system. Let me explain why.

This is me and my colleague Jesse back in 2006, sitting in front of the very first Tagformance prototype. We had just left our jobs at the university, and were frantically trying to build a system for testing the performance of UHF RFID tags. I spent hours of trying to understand papers written by Pavel Nikitin – then only a name to me. And we were able to pull it off: we got our system out to the market for RFID World 2007 which, by the way, was co-located with the very first IEEE RFID conference. Now, seeing our system used in one of Pavel’s papers 11 years later feels like the circle is closed.

Four Factors That Make Japan the Perfect Place to Deploy RAIN RFID in Convenience Stores

Apr 27, 2017

中文版 Chinese version

The Nikkei Asian Review released a story about how some of the largest Japanese convenience stores plan to deploy RFID as a fix to severe labor shortage. Firstly, I am personally a huge fan of Japan and secondly, I’ve done quite a bit of work to speed up RAIN RFID deployments in the retail market. Still this announcement from Japan took me by surprise, and let me explain why.

Nikkei Asian Review: New RFID self-checkout systems will eliminate the need to scan each item individually, helping to cope with a severe lack of manpower.

Unconventional Motivation

This is the first time I’ve heard labor shortage to drive the RFID deployment. In Europe and the USA it’s been more about omni-channel sales that creates sales uplift, and all the efficiencies that simply result from high inventory accuracy.

Still, as you give it a moment to sink in, isn’t this just perfect news – labor shortage as a new driver has emerged and greatly motivates several large stakeholders to engage in this initiative, including Seven-Eleven, Lawson, Familymart and even the Japanese Ministry of Economy, Trade and Industry!

For me Japan is the most intriguing piece of the plot, and let me outline the four factors that I believe will help this initiative all the way to success:

Factor #1: Collective Efficiency in Their Veins

The culture enables the Japanese to behave and act highly efficiently in extremely large and dense crowds. If a new form of practice is available to improve public efficiencies, the Japanese are the first ones to oblige.

Consider the notorious train rush every morning between 8AM and 9AM. The Yamanote Line, for example, is an amazing experience. With a ridership of over 1,000,000 passengers overcrowding is both a challenge and a fact. Keep to the left and go with the flow, yes, but there is more to the story.

Factor #2: Payment Cards as the Sixth Finger

You can’t get around in Tokyo without a Suica® or a Pasmo® card. Based on the Sony FeliCa® technology, these rechargeable payment cards enable the commuters to quickly pass through the ticket gates at the JR and Subway stations, and help maintain the efficient flow of people in the jampacked station platforms.

You can conveniently use the same payment cards for many of the small purchases you stumble around the stations. As you take a moment with it, actually kiosks, taxis, cafes and many other small businesses seem to even endorse Suica® over coins.

Factor #3: Ubiquitous Automation

For the sake of efficiency and convenience, a metropol such as Tokyo is filled with automation to assist the consumers. I’d especially highlight the vending machines that you can find around in corridors and even on the station platforms. Take the automated ordering systems at fast-food restaurants as the second example. Automation and advanced user experience even follow the average Haruto-san all the way to the restrooms as well.

Factor #4: Local Retail Technology Vendors

If one has ever visited the RetailTech Exhibition in Tokyo Big Sight, it is pretty clear for a Japanese retailer that there are many Japanese based top brands to choose the implementer partner from: Toshiba TEC, Sato, Fujitsu, NCR, Ricoh…. On top of that, there is a great number of local experienced RFID label solutions providers, such as FVG, Sato, Toppan Forms, Toppan Printing, and Fine Label to name a few. Altech provides expertise and solutions related to RFID label testing and manufacturing.

A local partner is a great asset for clearing obstacles and moving any project forward at a fast pace.

A Few Ideas to Support Success

As a few generations of Japanese consumers are native to utilizing payment cards and automation in their everyday life, the RFID based self-checkouts at convenience stores should be nothing new. The local ecosystem of RAIN RFID vendors already exists, so I would only list two long-term implementation success factors to closely consider by all the stakeholders:
1. Utilize EPC numbering for the tagged sale items, because proprietary item numbering systems overlap sooner or later and then erode the RFID system reliability
2. Utilize the GS1 TIPP Guideline to specify the tagged item performance requirements, because TIPP makes the deployment more future-proof and enables the suppliers to manage tagging economically.

Voyantic provides easy-to-use turn-key solutions for TIPP testing.

With this said, I hope all goes well with the initiative. Please drop me a line if you’d like to raise further conversation around the topic!
