Upper European RAIN RFID Frequency Band Increases Adoption

Nov 10, 2022

About the author

I enjoy seeing both the Voyantic employees and our customers thrive. The grand majority of my time goes into projects and initiatives that grow the RAIN RFID market in the long term. My remote office is on a boat on the archipelago of Finland.

How cool is NFC in that it simply works all over the globe: 13,56 MHz everywhere? How cool do you think it is, that RAIN RFID today enjoys the same: several reader channels between 902 and 928 MHz on all the continents!

Status up until 2018: two regulatory regions with no overlap

Traditionally, the end users and RAIN solution providers have accepted and adapted the fact, that in Europe RAIN deployments have been limited to operate at the 866-868 MHz range, also known as the ETSI range, where the four reader transmit channels are. The rest of the world utilized reader transmit channels somewhere between 902 and 928 MHz – the so-called FCC range.

The EU decided to harmonize the RAIN RFID band in 2018

After years of CEPT (short for European Conference of Postal and Telecommunications Administrations) technical studies and mounting pressure from the RAIN end users, the Commission Implementing Decision (EU) 2018/1538 specified three reader channels at 916,3 MHz, 917,5 MHz, and 918,7 MHz. The Commission also defined the implementation deadline as 1st February 2019 but acknowledged several exceptions for existing regional radio systems, such as military and railway deployments.

The picture above shows how well the European new RAIN RFID reader channels fit among the other global regulatory regions.

Status today: 902-928 MHz covered by a grand majority of countries!

As we study the RAIN RFID regulatory status document maintained by Mr. Craig Alan Repec of GS1 Global Office, out of the listed 81 countries with known status, 55 offer RAIN RFID reader channels between the band 902 – 928 MHz. Out of the CEPT 46 member counties, 25 have partial or full implementation for the upper European RAIN RFID channels, and that number is rising every year.

Performance benefits are significant

As one looks behind the numbers, you come to realize that specifically, the upper European band is wonderful news: more of everything! 

Comparison of lower and upper European RAIN RFID frequency channels

“The upper European frequency band definitely offers dramatically more wiggle room for RAIN engineers to optimize system and component designs,” says Dr. Jesse Tuominen, the CTO RFID of Voyantic.

Business benefits 

As most supply chains are global, it makes sense to keep the RAIN tagging specs at 860 – 930 MHz. This way tagging is responsive all around the globe, which adds simplicity to the deployments.

In certain applications, it might even make sense to narrow down the tagging specs to 902-928 MHz, as tagging and reader antennas can be further optimized for performance, footprint and, ultimately, cost. I believe this opportunity is especially interesting in applications, where there are severe space or area constraints for either the readers or the tagging.

What’s up with the slow adopters

Well, all I can say is that the RAIN RFID end users in Germany, the Netherlands, Croatia, Greece and a few other countries are in a totally unfair situation – they are outliers that remain limited to the lower European RAIN frequency bands for the time being.

For future-proofing RAIN RFID deployments also in Germany, please prepare to upgrade systems to support the Upper ETSI frequency band.

Having said that, I foresee that nuisance to eventually pass. My advice is to prepare to upgrade deployments as those reader channels become available later on. Practically that means requiring the deployments to be compatible with and upgradeable to the 915-917 MHz in the RAIN project specifications.

Bottom line: use the upper European reader channels and be appreciative of them!

The awareness around the global harmonized RAIN frequency band has been slim. However, numerous end users are embracing it. “Most of the main RAIN users in France have declared they are going to use the upper bandwidth for their deployment to get all benefits from this new frequency possibility”, says Hervé d´Halluin, Leader RFID & Traceability of Decathlon. “This represents tens of thousand of locations spread all over France.”

What about the appreciation? Regulatory advocacy is an area where industry stakeholders need to pull their ranks together. With the help of industrial associations, such as the RAIN Alliance, AIM and GS1, we’ve done just that. If you’re in the RAIN RFID business for the long run, make sure your company supports these associations by becoming their member, because regulatory work never ends.

Consolidation in the RFID Industry – Part 1: Connections Summit 2022 Edition

Jun 10, 2022

About the author

I am the CEO and co-founder of Voyantic, a company that specializes in RFID test and measurement solutions. Before starting Voyantic in 2004, I worked as a researcher at the Helsinki University of Technology focusing on passive RFID sensing for moisture in building structures.

Voyantic has been at the center of the RAIN RFID industry for the last 16 years. During that time, many new companies have been started, and many no longer exist. In addition, there have been some IPOs and acquisitions, but overall, the early years of RAIN RFID were pretty quiet on that front. But not anymore! During the last couple of years, a number of acquisitions have taken place. Usually, consolidation is a sign of maturity in the market as bigger players are establishing their foothold in the market.

I have been planning to blog about the latest acquisitions for a while, but it became quickly evident that there is just too much happening to be covered in one blog post. So where should I start? Well, why not close to home. Next week, on June 14-16, 2022, Voyantic is hosting the Helsinki Connections Summit together with Beontag, and Nordic ID, two perfect examples of recent acquisitions in the industry.

Beontag

The Helsinki Connections Summit was originally planned for the summer of 2020. Unfortunately, it was postponed twice because of the pandemic. Originally, one of the co-hosts was supposed to be Stora Enso, a publicly listed forest products company. They were relative newcomers in the RFID industry, known especially for their ECO RFID line of sustainable tags. Their RFID operations were based (where else but) in the RFID capital of the world, Tampere, Finland.

From Tampere comes also Confidex, a company best known for its industrial-grade RAIN RFID tags and labels, as well as contactless RFID tickets. Founded in 2005, they are an established and well-known player in the RAIN RFID industry.

Both Stora Enso’s RFID division and Confidex were acquired by Beontag in 2020 and 2022 respectively. Beontag is a Brazilian company – a rather new name in the business – but one that cannot have been missed by anyone following the industry. Lately, they have been the most active in the industry on the acquisition front, acquiring companies in Italy and France as well (but more about that in future blog posts).

Nordic ID – A Brady Business

Another host of the Connections Summit, Nordic ID, defines itself as Europe’s leading provider of item tracking and tracing solutions. Founded in 1986, Nordic ID is traditionally known for its hand terminals: first barcode scanning and then RAIN RFID. Lately, they have profiled themselves as both solutions and device provider. They are based in Salo, a town made famous by Nokia during its prime. 

Nordic ID was listed in Nasdaq Helsinki First North in 2018 and and was acquired by Brady Corporation in 2021.

Final note

There is plenty of RFID expertise in Finland – and this blog post barely touched the surface! Why not come and witness it with your own eyes at the Connections Summit on June 14-16. Your hosts Beontag, Nordic ID, and Voyantic are looking forward to seeing you there!

Stay tuned for part 2 in the blog series! Part two will cover a couple of other acquisitions within the industry. But let’s keep it a secret for now.  If you want to make sure you will not miss it, sign up to receive blog notifications to your email.

6 Tips for Tackling the Global Component Shortage

The electronic component shortage is hitting hard on pretty much any imaginable industry. We see that in consumer electronics; we had to wait for more than a year for my son’s Playstation 5. But also, the automotive industry, mobile devices, and several industrial markets are affected heavily. The RFID industry is no exception. Claire Swedberg wrote recently an excellent and multifaceted piece about chip shortage in RFID in the RFID Journal publication: https://www.rfidjournal.com/rfid-technology-rollout-strained-by-chip-shortage. The article is mainly focused on what is going on with RAIN tag ICs, but from what I have seen, also reader manufacturers and other players in the industry are affected.

My company, Voyantic, is a provider of test and measurement solutions for the RFID industry, so we are not supplying the kinds of volumes that RFID reader companies do, let alone tag manufacturers. But I thought it would be interesting to look at what the situation has meant for us and how we have dealt with it.

“Components Available in April – Next Year ” – What to do?

I had a chat with our head of operations to hear his thoughts on the situation. His overall feeling was that the amount of time spent in sourcing has increased, and in the worst points of time, there were new negative surprises in component availability almost every week. But so far, our operations team has been able to work around them. He identified three key points that have made it possible:

  1. Co-operation between product design and operations. Being surrounded by skilled people that know the products intimately has been the key. When there have been challenges with some components, electronics designers that can point out what is critical have helped to find replacement components, which have been delightfully abundant. Finally, in most severe cases the designers may have made slight design changes around difficult-to-find components. I have learned to highly appreciate our in-house hardware design capability and can guess how difficult it might have been if all that was outsourced to a distant country.
  2. Turning to your network to find trustworthy component brokers. When looking for alternative sources for components, there are thousands of component brokers out there. But the question is, who can you trust? Where do you buy without getting counterfeit or C-grade components? That’s where your network comes in. Who can they recommend?
  3. Geographic distribution. It has proven efficient to have trusted brokers on different continents; the one in Hong Kong may have a good inventory (and prices) for one product, and the one in the US for another one. Asking around often leads to the best outcome.    

Communicating with Suppliers and Customers

In addition to the operational measures above, the crucial part of coping with growing uncertainty is instilling trust and good communication with both suppliers and customers. I am sure that, during the last year, everyone has experienced a supplier announce a delivery delay just days before the confirmed delivery date. You don’t want to be that company, right? So, what should we do?

  1. Discuss order schedules in advance. Customer needs usually don’t materialize overnight. Discussing needs in advance, or even placing advance orders, helps production planning.
  2. Radical openness. If there is uncertainty in delivery times, why not communicate that openly. Which company would you want to work with in the long term? The one that gives you the nasty surprise just before expected delivery? Or the one that tells you where they stand and keeps you updated with any progress?
  3. Solving the customer’s problems instead of delivering products. Open discussion with the customer and understanding what they plan to do with your product and when they need it may reveal alternative ways to solve their problems. Maybe you can solve the most acute needs with services. Or maybe you have a demo product or a previous generation product that you can loan to the customer until the new product arrives.

It’s probably going to be another year or two until the component shortage gets any easier. I hope that as an industry, we, the RFID guys, can work together to get through it.

In 2021, RFID with sensing technologies continued to be a major research area. The COVID-19 pandemic was also seen in RFID research topics.

Plenty of interesting research papers were published and, unfortunately, I can only introduce a very limited selection of the research topics.

Sensor tags – sci-fi brought to reality

RFID combined with sensing continues to be the overwhelmingly most common broad research area in RFID. But research has clearly moved beyond the traditional sensor tags. Some of the described ideas and methods seemed more like sci-fi than science.

Sensing Covid-19

Covid-19 has inspired some research papers, and practical RFID-based solutions are being developed to help in fighting the pandemic.

Masks’ wetness can reduce their filtering capabilities. Do RFID-based sensors offer a solution?

Monitoring structures and machinery

Measuring and monitoring the condition of structures and equipment was another topic area for RFID research last year.

RFID could be used for the early detection of building surface cracks.

RFID sensors in medical applications

Combining RFID, sensors and medical diagnostics pushes biomedical sciences to a new level.

Wearable tags, miniaturization and hard to tag items

Textile, yarn, and wearable RFID continue to be another common research topic.

The stretching of fabrics is an issue for common RFID tag antenna designs. This paper introduces a way to create stretchable antennas suitable for textiles: Stretchable Textile Yarn Based on UHF RFID Helical Tag.

There are also several papers published around the topic of making ever smaller tags with higher read ranges, and using them to tag, for example, metallic objects:

Webinar Series for Barcode Pros – Getting Started with RFID Labels

Feb 01, 2022

About the author

32Voyantic Marketing

Content

Last year, we teamed up with TSC Printronix Auto ID and started a webinar series designed for barcode professionals, who are considering expanding their offering to RAIN RFID labels, or who already are at the beginning of that journey. With TSC Printronix Auto ID we saw the need for education as more and more barcode label customers are looking for RFID solutions. 

In the first webinar, What a barcode professional needs to know about RAIN RFID Label and Tag Data, we started from the basics: what are the key aspects of RAIN RFID technology and data, how does RAIN RFID actually work, what are the system components, and most importantly, where can you find more information. 

The second part of the webinar series, What a Barcode Professional Needs to Know about the RAIN RFID Encoding Processes, focused on the practicalities of the RAIN RFID encoding process, equipment, and alternatives. 

In the third webinar, What a Barcode professional needs to know about RAIN RFID label selection and sourcing, scheduled for February 10th, we will cover the most important considerations related to label selection and sourcing process including label specifications, supplier selection, delivery format, handling, and other issues.

Here are my main takeaways from the first two webinars in the series.

Key Takeaways from Part 1 

It is crucial to understand filtering in the context of RFID systems

The nature of RF signals means that they can go through walls and various other materials. A RAIN RFID reader can read a large number of tags simultaneously and without a line of sight, which is, in comparison, required for reading barcodes. For example, when you are inventorying tagged items in storage, your system could be reading tags behind a wall that should not be included in your inventory. Setting up tag filtering correctly ensures that your application works accurately, and that requires following proper data encoding processes. 

There are 9 RFID tags on the wall, but the reader found 54 tags.

There is no “one size fits for all” RAIN tag

What do you need to know about RAIN RFID tags when looking for a tag for your customer? The difference between a barcode label and an RFID label is that the RFID label includes an IC (microchip) and an antenna. Together the IC and the antenna make up an RFID inlay. There are lots of different IC models out there and the type of IC defines what kind of and how much data can be encoded in the tag. The antenna model defines how far the label can be read. Knowing your solution requirements, physical factors such as the label size and item materials, and use cases and data requirements are necessary for finding the best tag for your solution.

Do not use a proprietary numbering system

Keeping the importance of filtering in mind, it is crucial to understand the basics of RAIN RFID encoding systems, i.e., how you are putting data into a tag. There are three data standard families available for RAIN RFID tag encoding

Following one of the established data standards ensures there won’t be issues with tag filtering (and application errors) along the road.

The fourth option is to use your own proprietary encoding systems – Please do not do it! Or if you do, you need to “wrap” your system within the ISO standard or the RAIN numbering system.

Selecting the data standard to use often depends on your customer or the industry you are operating in. Some customers may mandate that you use a specific standard, and many industries have a mandated or de-facto standard in use to ensure interoperability.

Above are my key learnings of Part 1, but many more topics and details were discussed. Watch the webinar to learn more about each of the data standard families, including the structure of the different numbering systems and example use cases, as well as the basics of data security. Webinar part two dives deeper into the standard selection process and the specific advantages of the different standards.

Key Takeaways from Part 2

Label Manufacturing Process

The label manufacturing process includes three steps. In the first step, the IC is attached to the antenna, creating an inlay. In the second step, the inlays are converted in a common backing material called a liner, creating a blank label. In the third step, data is printed on and encoded into the label, creating a finished label.

While the process itself is simple, the manufacturing machines are quite complex. Watch the webinar to learn more ›

Encoding Equipment Types and Process

The suitable type of encoding equipment depends on the volume of tags that need to be encoded. The more sophisticated machines that can process high volumes at high speed naturally come with a higher cost.

An RFID reader can be used as an encoder but it is not an efficient permanent solution.

An RFID printer is purpose-built for encoding and is best suitable for small rolls and batches. They can be affordable and process up to some thousands of labels per hour.

High throughput personalization machines can take in larger rolls and process up to one hundred thousand tags per hour, but they also come with a higher cost.

And finally, encoding can also be integrated into product production or packaging lines.

Watch the webinar recording to dive deeper into the IC selection factors, encoding process steps, RAIN tag memory details, as well as tag locking and passwords – ensuring the right data is encoded in the right way.

The Personalization Process

The personalization process includes both printing data on the label and encoding the tags. The printed data can be the same data that’s in the RFID tag or include additional information. 

High throughput personalization lines often process labels in successive stations. Combining the print and encoding in a high-speed personalization process requires accurate triggering for all the steps and making sure the stations match the process flow.

An example of personalization stations in a high throughput personalization process.

Using an RFID printer for personalization is a good option for smaller-scale projects. An RFID printer prints the barcode and other designed details on the label as well as encodes and verifies the RAIN tag data.

RAIN Man’s Letter to Santa 2021

Dec 19, 2021

About the author

I enjoy seeing both the Voyantic employees and our customers thrive. The grand majority of my time goes into projects and initiatives that grow the RAIN RFID market in the long term. My remote office is on a boat on the archipelago of Finland.

Content

Dear Santa,

I hope all is well with you. What a year! Let’s do an instant recap:

What happened in 2021

I had not really accepted this fact early on this year, but towards the summer it started to sink in: the pandemic is business as usual. At least on Voyantic’s side business has been great.

On the RAIN Alliance side of things, I became the Chairman of the RAIN Board. It is an honor, it is exciting, and it has kept me busy. The Alliance has continued delivering good value for its membership. Specifically, I want to highlight two important developments:

  1. As a housekeeping measure, the Alliance launched the RAIN CIN numbering system. While it may sound like something brand new, it is actually an ISO based numbering system simply in a new wrapping. With this easy alternative now available, all stakeholders can start clearing up some of the deployments out there that do not follow any specific numbering system. 
  2. The RAIN RFID Tyre Expo in September was the first ever global event for the tire industry with focus on RAIN RFID. The program included presentations from the early adopters, such as EuroFit Group, FIA, Norauto and Michelin, as well as from the key RAIN technology suppliers, including Hana Technologies, Siemens, and Zebra to name a few. 

Lastly, due to the continued push by several stakeholders, the Global harmonized RAIN RFID frequency band took an important step forward as France implemented the Commission’s decision EU 2018/1538. I am sorry to say that this move puts the RFID end-users in Germany increasingly in an unfair position since they remain restricted to the lower ETSI band.

Looking forward to 2022

Dear Santa, the outlook for 2022 is better than ever. With that in mind, one needs to be cautious because of two persistent inconveniences: 

Inflation went up and stays up

“We see inflation rising further in the near term but then declining next year”, says Mrs. Lagarde of ECB.

“Nonsense”, I say.

I see three factors in play, that will keep inflation up for a long time: the green energy transition, trading of emissions, and excess supply of money. While the last will go away, the two first ones are here to stay, I would add, simply because humankind is doomed otherwise. In a relatively short time, those factors already contributed to the rising price of energy. Slowly that price increase has bloated prices of raw materials and logistics. Eventually added costs will creep into everyday products and services. All this takes time, and therefore I don’t think inflation is a temporary phenomenon.

Dear Santa, please pass the following message to Mrs. Lagarde – “Juho hopes you’re right, and he is wrong.”

Component shortage gets businesses stuck

You are stepping on the gas pedal with orders coming in, but nothing moves or goes out the door. The component shortage is like fine deep sand underneath your business tires. 

At Voyantic we have been fortunate to have been able to manage our supply chain up to these days, but we have seen our customers struggle. That struggle eases up over time, but with the stock levels down through the supply chains and the price of logistics going up, I don’t see a fast way out of this. What that means is that the speed of business will be reduced, with longer lead times and more waiting.

Beer and a good night sleep in a prison

I cannot wait for the return of the in-person meetings. An RFID enthusiastic’s highlight of the year will be the RAIN Alliance meeting in Helsinki 2022. While at the event, as you agree to have “a beer at the lobby bar”, effectively you shall have “a beer in a prison“.

The event will be hosted by Beontag, Nordic-ID, and Voyantic. Mr. Nikias Klohr of Race|Results has volunteered to time your performance as you sprint over the prison yard and the wall. 

Take the shots, wear a mask, and get yourself to Helsinki on the 14th to 16th of June, 2022!

Happy Holidays!

Dear Santa, with the meeting restrictions tightening up again, you might be in for a similar Christmas tournée as the FedEx guys are – no hanging around in the living room, just deliver and get going. Look at the bright side: you will get to sauna a bit earlier!

NFC Forum’s Wayfinder Mark System Improves NFC User Experience

Nov 18, 2021

About the author

In a blog article published in 2019, I described a few experiments that tested the level of NFC user experience. One of the conclusions was that users have issues with connecting the NFC tag and the reader device, due to a lack of detailed knowledge of the antenna locations. I noted that: “NFC forum should recommend system integrators and manufacturers to indicate clearly where the tag is placed, and where the phone´s antenna is located. “

Now NFC forum has published the Wayfinding Mark System. The marks are used for showing users the NFC tag placements, where the reading device antenna is, and whether the NFC functionality is used for charging or just for communication.

Read the detailed instructions and sign the trademark license agreement at the NFC forum website.

  • The Wayfinding Mark is free to use.
  • Just the license agreement needs to be signed.
  • And obviously, the mark should be used as intended.

Wayfinding Mark Variations

There are 4 variations of the mark.

Image source: https://nfc-forum.org/wp-content/uploads/2021/11/Wayfinding-Mark-Guidelines.pdf

The default mark is “directional”. It can be used on tags and devices. It guides users to find the exact position of the NFC tag and antenna.

A “simplified” version can be used when users are expected to be more familiar with the NFC use case.

Many NFC devices have also the possibility to charge wirelessly via the NFC interface. This is indicated by a charging variation of the Wayfinding Mark. The “charging” mark should only be used when charging is possible.

NFC Powered Marketing

Another blog I wrote in 2019 presents an example of how NFC can support effective marketing and storytelling.

The Wayfinding Mark is the correct way to indicate the tapping position on a packaging or other material.

The Wayfinding Mark is royalty-free and easy to use. The more it is used by NFC device manufacturers and system providers, the more aware consumers will be about the mark and its meaning. And that will significantly improve the user experience of all the NFC systems.

Please, take the Wayfinding Mark into use.

The First-Ever Global RAIN RFID Tyre Expo – Recap

Sep 30, 2021

About the author

32Voyantic Marketing

Content

The third Engage Again Virtual Conference by AIM and RAIN Alliance took place September 8-9, 2021 and this time it was co-located with the first-ever RAIN RFID Tyre Expo – an event solely dedicated to the technology and use cases of RAIN RFID enabled tyres. The Tyre Expo was targeted atr people from all aspects of the tyre world including tyre manufacturers, distributors, dealers, and vehicle makers as well as technology and solution providers.

The conference program covered a wide range of interesting topics, that were arranged on three parallel tracks. Rumor has it that the Tyre Expo conference track continuously attracted an average of 60 people, making it the most attended track of the Engage Again event.

1. The Secret Sauce

Voyantic naturally took part in the fun as well, as a sponsor and by presenting together with Hana Technologies. Also, Juho Partanen from Voyantic moderated an expert panel discussion on the key levers for the growth or RAIN RFID adoption across the tyre industry.

Watch the panel discussion recording

In their presentation, Teemu Ainasoja from Voyantic and Randall Grein from Hana Technologies shared the story of how millions of Hana Technologies manufactured and Voyantic tested RAIN RFID tags have been successfully embedded into tyres, and at the same time, paved the way for other tyre manufacturers who are not yet working with RAIN. The technology and processes have been established, tested, and proven as tens of millions tyres are source tagged in 2021!

Watch the presentation recording

Teemu Ainasoja & Randall Grein on the stage

Combining the messages from these two presentations: the secret sauce to success is collaboration across company borders. It applies both on 100% successful source tagging of tyres, information sharing within supply chains, as well as accelerating the adoption of RAIN technology across the tyre value chain.

Enabling source tagging of tyres was not easy. There were technical and other hurdles to overcome. Now, those hurdles are passed and any new tyre manufacturer can jump on-board the tyre tagging train quite easily.

2. Looking into the future

Voyantic had a good crowd of employees attending the conference. Here are some of the key takeaways our staff shared from the event.

  • The RAIN tagging of tyres is driven by traceability needs thorough the tire life cycle, not only through the supply chain. The circular economy seems to be another long-term driver.
  • The tagging penetration in 2021 is around 3-4 %, still adding up to tens of millions of tires. The volume is projected to leap to a few hundreds of millions by 2024, as Michelin extends tagging to cover all passenger car tyres, in addition to truck and transport vehicle tyres that are already tagged today.
  • Embedded tags seem to become the dominant application method, however, it is not clear whether embedded tags can deliver the needed reading performance through the whole supply chain. That would leave the market open for sticker-type tagging specifically in tyre distribution and sales.

Siemens believes that RAIN tagging of tyres will become an industry-wide norm. Quote of the week came from Dieter Horst of Siemens “tires are not conceivable in the future without RFID connectivity”.

Voyantic offers RAIN RFID testing and encoding systems for tyre manyfacturers’ systems. The systems include:

  • Tagformance system with C50 measurement chamber / C100 measurement chamber / C150 measurement chamber for anyone developing tags for tyres or tyre tagging.
  • Tagsurance system for production quality testing of RAIN RFID tags, including tyre tags.

Switching into a New IC in Inlay Design – Is There a “Quick n’ Dirty” Way?

Jul 01, 2021

About the author

I am Sales Director at Voyantic. I have over 15 years of experience from the RFID industry in Europe and the USA. I have two master's degrees: in industrial engineering and in marketing, and two patents in auto-ID technology. I am actively participating in RAIN RFID alliance activities.

A few months ago, I started receiving questions about switching to a new IC in inlay manufacturing. All these vendors had done several IC changes over the years, but there was something new going on. The questions were centered around possible shortcuts in the process.

  • “What if I just change the IC and don’t change the antenna design at all?”
  • “What if I don’t waste time in machine settings and just do it quick n’ dirty?”
  • “Are there any ICs that are ‘plug and play’ with other models?”

Unfortunately, I could not offer any help. I did find the question interesting though. At first, I tried to figure out some approaches on my own but did not get past the very basics. That is when I asked help from my colleagues Juho Partanen and Jesse Tuominen, and started doing some research on the topic.

In scale comparison of Impinj M750 and Monza R6

Together with Juho and Jesse we put together a whitepaper that outlines the process and key considerations for switching from one IC to another.

Download the white paper

Key considerations for switching from one IC to another

The IC vendors have plenty of helpful material available:

  • IC Datasheets
  • Reference antenna designs
  • Industrialization guides.

Some of the material is not publicly available, so reaching out to the IC vendor for help is a good starting point.

  • Start by verifying the suitability of the IC functionality.
    If you only need 96bit EPC pretty much any IC can do it. But some IC’s have a lot more functionality. More EPC memory, different amounts of user memory, and they support various optional EPC gen2 commands.
  • Then focus on production.
    Getting all the details and settings in the IC attachment process adjusted for the new wafer, for the new IC, and possibly for the new bonding paste can take time. This is also a time to check the durability of the new IC attachment.
  • When the production compatibility is confirmed, focus on the antenna design.
    Optimizing antenna design is always recommended, and with the IC vendor’s reference designs as a starting point, the design is not that huge of a project. In some cases, it is possible to take small shortcuts, but the time saved is not much. A good and optimized design is a better approach.
  • Focus on quality.
    As with designs, shortcuts do not make sense. The best approach is to fully utilize the new IC and optimize the tag performance and quality.

For more than a decade, RAIN RFID tag antennas were etched, and the substrate was PET film. Copper was first substituted with aluminum, and various other technologies have emerged, such as printed antennas, and cutting, milling, or laser engraving metal foils.

More recently we have seen antennas being applied on paper and even directly on the packaging and on other surfaces. Much of that development has been driven by cost, but the ecological and sustainability aspects are rising in importance.

Juho Partanen recently moderated an online panel discussion on various aspects and implications of sustainability and eco-friendliness of RAIN RFID tagging. The panelists included Sipi Savolainen from Stora Enso, Jerome Lemay from Decathlon, and Emmanuel Arene from Primo1D. The discussion ranged from ecological tag materials to the technology itself contributing to system-level sustainability through enabling and driving applications for the circular economy.

Before the discussion started, we asked the attendees how they would rate various aspects of eco-friendliness? A quick poll revealed the following:

The initial attendee views support the notion that although moving to renewable and recyclable materials for the tags is a no-brainer in terms of eco-friendliness, there needs to be a more holistic view of the whole system – how the technology enables cradle-to-grave traceability, waste reduction, efficiency improvements, transparency plus other aspects crucial for driving the circular economy and sustainable consumption.

We received a lot of attendee questions during the discussion and since the webinar time was limited, we were not able to address them all during the live session. So we asked our panelists to provide some additional answers for this blog.

Follow-up Q&A from the panel discussion

The responses to the following questions have been written by Mr. Sipi Savolainen from Stora Enso.

Question: If a tag is paper-based, could it be placed in the paper recycling bin, as it includes electronics and metal?
Answer: All paper and cardboard recyclability testing is based on the ability to separate non-fiber-based materials from fiber materials and screen those components before re-pulping. According to the results of PTS RH 021/97 Recyclability of Packaging Products and TAPPI UM 213 Repulpability testing (mod.), ECO tags are recyclable within paper and paper board recycling processes.

Question: According to WEEE regulation, RFID label is still regarded as electrical waste, I doubt if the paper-based label can be recycled as paper?
Answer: Passive tags are considered to fall under the scope of the WEEE directive. However, as tags are being attached to items they are naturally disposed with the material/object they are applied to. The best suited waste management process is defined based on the material/object type.

The response to the following question comes from Jerômé Lemay from Decathlon.

Question: What are the most influential factors that can move world businesses towards practicing environmental sustainability?
Answer: For Decathlon, sustainability is considered in a holistic way and, in addition to preserving nature, also includes taking care of people, and creating sustainable value through governance and business ethics, for example. Environmental sustainability is the third pillar and includes tackling climate change and driving the circular economy.

Environmental sustainability needs to be incorporated into the strategy and values, and forward-looking businesses should see that it is also what their customers are expecting.

The response to the following question comes from Emmanuel ARENE of Primo1D.

Question: Obviously, depending on which material the Primo 1D is embedded it changes its perfromance. Is the antenna re-tuned for each different material?
Answer: Yes, the performance of our embedded system is intimately linked to the permittivity of the tagged item. To make sure the RF performance and durability are optimized for each material, object, and use case, different elements can be tuned: the antenna material and its design, the chipset, and the packaging of our RFID UHF tag as well. Primo1D has all resources in-house to support product development and industrialization process till ramp-up.
