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

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!

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

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!

GS1 Releases the TIPP Global Guideline – Streamlines RAIN RFID Adoption in Retail and Fosters Tagging Innovations

中文版 Chinese version

After over 18 months of hard work, the TIPP work group under the GS1 Global Office has now released the Tagged Item Performance Protocol (TIPP) for global usage. The guideline focuses on readability of tagged items, supports all the global RAIN RFID frequencies, and also comes with additional supportive documentation to make the adoption process easier.

Many experts have invested a considerable amount of time in the creation of this guideline, and I am personally pleased with the outcome. The feedback that I’ve already collected leads me to believe that the standard lays out useful guidance also for RAIN RFID projects outside of the retail sector. Read on to learn what this standard means for the industry and end users.

TIPP Simplifies RAIN RFID Adoption for Retailers

The early adopters of RAIN RFID technology needed to cope with plenty of piloting, in-store testing and other iterative procedures to make the technology work out for them. A decade later, now in 2017, both the technology itself and the surrounding ecosystem have matured. Standards also emerge to make adoption of technology easier, faster and less expensive.

TIPP grades establish a common vocabulary and methodology for the RAIN RFID ecosystem. Original chart adopted from Impinj Inc., with modifications.

The end users define their specific tagging requirements as TIPP grades that are easy to communicate between stakeholders. Similar standard communication methods are already utilized in barcoding, EPC tag data standard and product attributes – standards boil down complicated technical issues into simple ones thus removing headaches and misunderstandings.

But wait a minute – some retailers rely on the approved inlay lists from the ARC Program, so what is the relevance of TIPP for them?

TIPP Scales – Removes Bottleneck of the ARC Program

The well-known ARC Program uses a sophisticated test system to gather and compile a database of RFID label performance characteristics. Combined with the end user specific requirements gathered during pre-pilot tests, the local experts then maintain certified inlay lists across retail item categories.

However, a limitation of the ARC Program is that the only official place to perform the tests for a newly developed inlay or retail item category is the one Auburn University test laboratory in Alabama, USA. There are only a limited number of experts available for pre-pilots, thus a bottleneck gradually developed.

As the number of deployments started rising across continents, the ecosystem simply needed methodology that scales. Now that the TIPP guideline establishes open grades and open test methodology, anyone can start performing TIPP tests locally and the bottleneck is removed.

Under the hood TIPP is about 95% the same as the ARC test setup. The main difference is how the test data is interpreted. In fact it should be acknowledged that the ARC Lab Director Justin Patton and Director of Technology Dr. Senthilkumar CP both gave significant contribution during the creation of TIPP US.

TIPP grading test system is essentially a similar 4 channel setup as the ARC test system.

Building the Future for Smarter Packages

An aspect of TIPP is that it enables tagging solutions providers to innovate with new breeds of smart packages since they are no longer dictated to work only with inlay-based RAIN labeling. Moving away from diverse inlay lists also brings increased possibilities for suppliers to drive down the cost of tagging. In this perspective I don’t expect the cost of an inlay to drop as such, instead I am confident that management, stocking of labels and finishing processes around tagging will find new efficiencies.

Origins of TIPP Date Back to VICS and ILRI

For the folks out there that want to understand how TIPP came to existence, I’ve gathered a brief history piece in another document. If ILRI, VICS or ARC Arkansas rings any bells, you may want to give the History of TIPP document two minutes of your time.

In essence TIPP is rooted on

  1. the joined effort within the retail industry to increase the efficiency and transparency of supply chains
  2. the pain that RFID projects caused for the early adopters in the retail industry
  3. the learnings from prior technology implementations, such as barcodes
  4. the ongoing RAIN RFID deployment evolution from handheld scanners to zone sensor infrastructure.

Next Step: Guideline to Be Adopted by Retailers

As the TIPP guideline was developed for the retail community by the request of the retail community, I next look forward to the retailers and their suppliers to start adopting this global guideline. To make the transition smoother this time around, the guideline comes with supportive documentation both for the retailers and solution providers.

The GS1 TIPP website offers new fantastic documentation for both techies and non-techies.

Needless to say, if there are any obstacles on the way, both the GS1 Member Organizations and technology vendors are glad and available to assist. A new test protocol for dense stacks will be added to the standard in Q2/2017 together with new grades – mighty good news for anyone in the sporting goods business!

Over time we all should learn more about the benefits that the standard offers. When it comes to simplifying RFID vendor compliance management, my recent blog post already discussed that side of the story.

Methodology Likely to Find Ground Also Outside of Retail

I’ve had the privilege to explain and justify TIPP for various stakeholders over the recent couple of years. Received feedback suggests that the end user segments outside of retail consider TIPP as a benchmark of how to express tagging requirements in a scalable way. One hurdle for those folks in various businesses will be to find and motivate an un-biased association to efficiently nurture the standard creation – same as VILRI and later GS1 did for retail.

RFID Triumph at Macy’s: More Sales with Higher Margins – GS1 Connect 2016 Recap

中文版 Chinese version

It was my third time to attend the GS1 Connect event; this time in Washington, DC from May 31st through June 3rd. The event was loaded with an impressive conference menu and a larger exhibition area than in the Austin event last year, although with less exhibiting companies than previously. RFID was well presented – read on to see what I am taking home from that perspective.

Utopia Comes with Transparency and Traceability that Protects Both Business and Consumers

Standardsville is a picturesque city where everything is clean, convenient, traceable and safe. Business blooms because information and goods flow without obstacles, and The Consumer is protected from harm. Actually I thought GS1 had done a really nice job on creating this Standardsville utopia as the theme of the event.

Standardsville comes with plenty of convenience and color. Picture Copyright GS1 2016.

In his keynote speech Mr. Bob Carpenter, the President and CEO of GS1 US, highlighted RFID as one of the transformational technologies that is currently reshaping retail. In a conference session the same message came through the presentation of Dr. Bill Hardgrave of Auburn University. Dr. Hardgrave listed the “Big Four” Foundational Use Cases of RFID together with the additional current driver: the omni-channel retail.

Retail use cases of RFID according to Dr. Bill Hardgrave, University of Auburn

For the most effective RFID execution Dr. Hardgrave again gave the ultimate guidance: “Move to 0HIO“.

RFID Is a Strategic Enabler for Macy’s

In the Macy’s HTDBW session Mr. Bill Connell, Senior VP of Logistics at Macy’s, explained the reasons why Macy’s is so committed to RFID – sales uplift is naturally the ultimate reward, but all the other benefits of accurate inventory also add enormous efficiencies to store operations. The consumer sees all this as improved shopping experience, whether she is online or in-store.

Supplier Source Tagging Is Happening Already

Mr. Connell also made it clear that supplier source tagging is the only way to do this right so that benefits are spread thorough the supply chain. Today tagging coverage among Macy’s suppliers is 56%, and Mr. Connell expressed his wish that the rest would start tagging tomorrow.

In a separate session Rich Haig, the CIO of Herman Kay, one of Macy’s suppliers, presented their experiences around RFID. The added visibility that RFID has brought to their own processes has dramatically affected shipping routines and raised accuracy to a whole new level. All this has made Herman Kay a better supplier for all their customers.

Many Retailers Put Emphasis on Product Attributes and Rich Content

As omni-channel retail marches forward, it seems that most retailers have their focus on getting the content right on their webstores. As an example, Walmart is focused on getting every single item online, including those that they are not currently even selling! As an engineer I am struggling to follow this logic, but I suppose that’s just me.

I understand rich content and romancing the product is essential to fight the online competition. However, behind the curtains many are following what the spearhead retailers are doing around RFID. For the latecomers implementing RFID is going to be a smoother ride because supplier source tagging is already happening, standards are emerging to make communication easier between stakeholders, and successful tagging solutions have become a common knowledge in many product categories.

TIPP Is Like the Air We Breathe

So, why are the retailers not implementing the Tagged Item Performance Protocol (TIPP) that was just recently developed for them? I’ve learned this actually is just an illusion. The way professional RFID tagging in retail is done today is solely based in TIPP-like methodology – some just call them ARC tests and others Voyantic tests. Common factors include tags applied on products/materials, organized to in-store like product stacks and then tested over a wide frequency band and across rotation angles.

TIPP grades will take their place as a communications method as tagging spreads to new product categories and new retailers. This is already happening, and I am sure the TIPP methodology will be discussed more at the GS1 Connect 2017.

GS1 Connect 2017 Taking Place in Las Vegas

As business moves forward the next GS1 Connect will be held in Las Vegas. Unfortunately the event is moved forward by a couple of weeks to 19th-22nd June, which will be right on top of the Finnish Midsummer’s Eve – the magical nightless night. Considering the night in Las Vegas may well be somewhat similar, I will be faced with a difficult decision between bonfires and casinos.

Why RFID TIPP Grading is Great News for the Retailers Worldwide

What does EU tax harmonization, the war in Ukraine, and TIPP adoption have in common? All three appear to be stagnant battlefronts with plenty of hard work done behind the scenes but minor visible progress to outsiders. Is there something wrong with the world order, how to move forward? Relax, take a sip of Dr. Pepper and read on to see why and how TIPP will prevail.

What Do TIPP, Tire Sidewall Codes, and Automotive Oil Grades Have in Common?

TIPP is an acronym for Tagged Item Performance Protocol. The TIPP methodology was initially created in the USA to simplify and standardize the communication and accountability around RFID tagging. RFID tagging of retail items dramatically improves inventory accuracy. Without RFID, it is impossible to sustain accurate inventory, especially on the shop floor level, and without accurate inventory a retailer cannot effectively execute their omnichannel sales strategies.

With this said, TIPP is a significant leap forward for any RFID adopting industry that looks to cut tagging costs, simplify communications, and clarify accountability. This approach would equally well serve the RFID adopters in the healthcare, automotive, and aerospace industries. It comes gift-wrapped by the GS1 US, too!

Little something for our friends!

The TIPP approach bears an analogy to car tire codes. The standardized information on the tire sidewalls describes the fundamental characteristics of the tire and is mandated by US Federal Law and EU Directives. Adapting to this system, the car manufacturer carefully masters the product (car) design, sets the tire requirements with a few alternative sizes that the car owners then follow. Periodically there is the unbiased 3rd party to check that a particular car has tires that meet the specs, are not damaged nor too worn out. In all these technical affairs, the tire manufacturer’s responsibility is to come up with the numbers and put them on the product. The tire brand is devoted to the sales and marketing side of things.

Tire sidewall markings include plenty of information for the consumer. “Tire code – en” by F l a n k e r – Own work. Licensed under CC BY 3.0 via Commons.

I will take a second example also from the automotive industry: SAE oil grades. Most car makers don’t endorse Total, Shell, nor Valvoline above others, but simply specify multigrade SAE 5W-30 in the owner’s manual, perhaps with little twists as BMW-LL-04. These grades have temperature-viscosity built-in, which makes a real difference up here in the North Pole. This valuable classification work was done by the Society of Automotive Engineers – SAE, which also has set standards on the quality side. SAE oil grades lay the grounds for easy purchasing, healthy competition, and results in fewer engine problems for us all. In this setup, the oil brands play an important role that is simply fenced off from the underlying oil grading system.

These two examples illustrate how grading systems have made two major industries more transparent, efficient, and streamlined. Sure it took years to develop and enforce these common practices, but the outcome benefits everyone.

Maintaining Approved Inlay Lists Becomes Too Complicated as RFID Tagging Expands to New Product Categories

Before the TIPP was established, the early adopters of RFID came up with their ways of getting tagging done in a controlled manner. Often this meant countless hours of the trial-and-error type of testing, and the outcome in many cases was lists of approved inlays that are suited for a particular product category. Suppliers were then instructed to use inlays from those lists, and just for a while, the process seemed to be alright.

Gradually the pain started to manifest itself. Because an inlay product is in constant evolution, maintaining of inlay lists often turned out to be quite a burden. To make the situation even more uncomfortable, the amount of testing is dramatically increasing as RFID tagging expands to new product categories. Even suppliers were unhappy due to extra effort and expense because conflicting lists from different retailers lead to exception tagging.

Adopting TIPP Is Evident, But There Are a Few Speedbumps Left on The Road

GS1 US did a fantastic job in pulling retailers, suppliers, and RFID industry experts together, and as an outcome, the TIPP grading system with eight initial performance grades was introduced in January 2015. The test methodology was documented on the protocol, physical and practical levels. A logical and well-documented alternative to the approved inlay list processes had been introduced.

The TIPP Guideline also includes grades for stacked retail items.

So why is it that the US retail’s giants did not instantly adopt TIPP? I would list four factors:

  1. The TIPP grades are not intuitive – which one to pick, and what to do if none of the eight alternative grades meet the read scenario requirements;
  2. How to verify for the TIPP grades – RFID technology vendors have not yet introduced routine validation methods for TIPP graded retail items;
  3. Many retailers are managing global supply chains, and they would rather adopt a global standard around RFID tagging;
  4. From the perspective of a multi-billion dollar retail company, slowness is an integral part of “instant”.

All these issues can and will be resolved; it just takes time. The road ahead is, therefore, paved with education, training, convincing, waiting, and politics. This rough terrain is nothing new since most RFID vendors are ideally used to it already for a decade.

Even slow progress is progress. Image courtesy of Hold the Mustard Postcards ©1980.

The Industry Is Multitasking And Making Further Progress

The vital steps that technology vendors and GS1 should take include making the TIPP grades more understandable, adding new grades in the portfolio, and introducing validation methods. All these issues are being addressed as we speak. In fact, for validation, there are already the first out-of-the-box solutions available, as you can see from the videos below.

On top of this great news, the GS1 Global Office is making a strong effort to develop a TIPP global standard. Retailers in the US, Europe, and Asia should all contribute and support GS1 in getting the global standard out promptly.

All this takes time. Many stakeholders are working on it, and it’s going to turn out great. Please contact me ( for further insight!

Tagged-Item Grading Helps Retail UHF RFID Projects

Retail and the retail supply chain are among the most significant users of UHF RFID technology. However, retail RFID projects are not the most simple ones. Items in retail come in all shapes, sizes, and materials. They are shipped in different boxes and stored and displayed on all kinds of racks, shelves, and tables. Also, different readers are used in various applications: logistics tracking, inventory count, RFID EAS, POS, and so on. I was involved in several retail RFID projects, and I have seen how complicated the performance optimization can be.

GS1 Tagged-Item Performance Protocol (TIPP) was developed to help retail RFID by making buying and selling tags easier. But what do the TIPP guidelines mean, and what kind of testing is required?

Goal: Accuracy in Inventory Counting

The purchase of RFID tags for retail items used to be complicated. The goal is simple: to have good counting accuracy (read rate) and a long and controlled read range. But I have seen how simple read range and counting accuracy requirements turn into a complicated mess of lengthy and costly field testing and piloting. Tags and readers are often selected separately, and system-level optimization is left to a trial-and-error process, if not entirely forgotten.

One approach used to be describing various use cases in detail and relying on the suppliers and technology providers to deliver tags that would work in all of the applications. The supplier was accountable for performance but had in practice minimal possibilities to achieve the goal.

Another strategy was to test extensively and to list accepted tags for different product categories. That way, the supplier was no longer accountable but was forced to buy specified tags without a possibility for price competition.

Finally, when using TIPP, the supplier is accountable for performance, and also has all the tools needed for delivering and verifying it.

Tagged- Item Grading Makes Retail RFID Projects Easier

The Tagged Item Performance Protocol makes buying and selling tags easier. The idea is familiar with many goods, from engine oils to clothes. It is a lot easier for a buyer to purchase shoes of size 41 than to provide a list of different measures of the foot. And it is a lot easier for the supplier to produce, stock, and sell shoes with a few different sizes than to verify that the unique requirements of each customer are met.

Similarly: it is easier to buy and sell tagged items performing according to a grade S05B than to list and verify all relevant performance requirements individually. As a result, a retailer’s list of requirements could be, for example:

  • items to be tagged with UHF RFID tags with C1G2 protocol
  • tagged items following GS1 Format & Symbol Placement for the Electronic Product Code guideline with C1G2 protocol
  • performance according to GS1 TIPP S05B grade
  • coded with SGTIN-96.

Now there is no longer a need to describe in detail which RFID tags to use and how to place them. Also, the suppliers and tag providers don’t need to guess what the use case description means from an RF performance point of view. TIPP translates complex system-level requirements into simplified component level pass/fail verification that any vendor can handle themselves.

The Voyantic Tagged-Item Grading System is 100% aligned with the GS1 Tagged-Item Performance Protocol (TIPP). The system automates TIPP grade validation and testing and provides results quickly and easily. It also enables TIPP grade audits to be performed by anyone. The Voyantic Tagged-Item Grading System is available as a complete turn-key setup.
