Downgrading Your Spec Does Not Make a Quality Tag - Thoughts About RFID Quality
Published on by

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…

What Gen2v2 Security Offers for RAIN RFID Applications
Published on by

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.

This Doesn't Look Right - Should I Contact Technical Support?
Published on by

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? 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 result, it’s just like with your car. What’s wrong? Should I contact Voyantic Technical Support?

National UHF RFID Standards and RFID Performance
Published on by

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, and in China, a new UHF standard, GB/T29768-2013 has been recently published.

There are several chip and tag manufacturers working with these new standards. Why do these national RFID standards exist? And what does it mean for performance testing?

How to Improve Efficiency of the R&D Team in UHF Tag Design
Published on by

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 basic measurement you may use various methods and even a simple method 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 huge. So, where does the efficiency come from?
