Evolution of organisms is one broadly accepted theory. Let me walk you through the many phases evolution has taken when it comes to RAIN RFID tag testing. How we got from RCS to TIPP and where are we heading?Read more →
I work as the CEO of Voyantic, a company that specializes in RFID test and measurement equipment. Since our systems are used by hundreds of companies around the world, we often come across cases where a customer needs our help to verify that their tags work as they should. This is a story about a case where things went wrong…Read more →
In October 2013, the management board of GS1 ratified EPC Gen2v2, a new version of the widely used Gen2 UHF RFID standard. Gen2v2 is backwards compatible with Gen2 but adds a number of new features for consumer privacy, authenticating tags and readers, tag memory management, and electronic article surveillance (EAS). These new features ease the adoption of RFID especially in application areas where the tag carries more information than only its identification. Let’s have a more detailed look at one new key feature of Gen2v2: authentication.Read more →
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?
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?Read more →
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?Read more →
