When selling RAIN RFID tags: wouldn’t it be great to prove that the proposed tag is the best possible for the customer’s application; and not just send out loads of free samples hoping that customers test them accurately? And when purchasing: wouldn’t it be great to have comparable data of how each tag works in your application instead of “our tags are the best ones, you can trust us” statements?
Guess what: it is possible, and in most cases, the salesperson or buyer just needs to know what to ask. Tag developers have a lot of characterization data ready. Read on to see how to leverage that data following the 3-step approach!
What do you do if, one morning, a new light with some strange symbol is suddenly lit on your car’s dashboard? You probably pull over and start browsing the car owner manual. You may be a little worried. Did I do something wrong? Can I fix this myself, or does the car need to be serviced? How long will I need to survive without my car?
In the same way, your Tagformance, the RFID test system that you typically use every day may have a problem you need to solve. You may already be an experienced user, or maybe you have just recently started to work with the system. When a new error message pops up or you get unexpected measurement results, it’s just like with your car. What’s wrong? Should I contact Voyantic Technical Support?
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.
Retail RFID seems to get the most limelight in the RFID industry at the moment. And that is not surprising because of its huge tag volumes and growth rates. But many other sectors are benefiting from RFID use as well. One of my personal favorites is the aerospace industry. To serve this industry, an ecosystem of RFID technology providers has emerged. Besides, the ecosystem has generated business opportunities for the supporting industry.
ISO 18000-63 (6C, EPC Class 1 Gen 2) has been by far the most used UHF RFID standard for several years. There have been some competing standards such as Tagidu, IP-X (tag-talks-only), and ISO18000-62 (6B), but they are nowadays rarely used in new applications. However, new RFID standards still emerge: for example, in Brazil, SINIAV has created a protocol aimed for vehicle tracking applications. In China, a new UHF standard, GB/T29768-2013, has been recently published.
Several tag manufacturers work with these new standards. Why do these national RFID standards exist? And what does it mean for performance testing?
I saw my first combined UHF RFID-NFC apparel label at a trade show several years ago. I remember wondering what the reason for this combination was. After all, UHF RFID is primarily used in the business-to-business world of retail: supply chains, inventories, point-of-sale, etc. NFC, on the other hand, is used in the business-to-consumer interface: in retail, primarily brand enhancement. Could there be a reason to combine these two technologies?
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 have 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?
Being responsible for sales of RFID performance measurement solutions, I’ve had the privilege of meeting with several companies and their design professionals around the world using very different methods for measuring UHF tag performance. Which is the best method then? I’d say it depends on your requirements – for a single essential measurement, you may use various methods, and even a simple technique can be sufficient. However, if you are looking for a way to improve the throughput and efficiency of your R&D team in tag design, the differences in methods are enormous. So, where does the efficiency come from?
RFID reader frequencies are controlled by governments and limited to narrow frequency bands that vary around the world. When the performance of a UHF tag is evaluated, focusing only on the narrow reader frequency bands is misleading. I have seen in several RFID projects, how the tag performance in field conditions is different from what is expected, leading to delayed projects and expensive re-planning. Testing in a wide frequency band is needed to get the correct information about and excellent visibility into UHF RFID tag performance. Read more about wideband testing and what it reveals from UHF RFID tag performance!
One of the hot topics at this year’s RFID Journal Live! trade show in San Diego was passive RFID sensing. The show featured several new sensor products from companies like RF Micron, Smartrac, Phase IV Engineering, Farsens, and many others. But what is passive RFID sensing all about? And should you already be working with it?
