Testing Requirements of NFC/RAIN RFID Dual Frequency Labels in Production
Published on by

There are applications, where fast data collection and high read distances of RAIN RFID (UHF) tags fulfill the overall application requirements only partially. Especially the missing capability of a consumer to easily access the tag contents limits the usability for marketing, product information and authentication purposes. A NFC tag would remove that limitation but also induce additional costs and complexity to the label finishing stages: double encoding and possible data compliance verification between these two tags. Interestingly the first IC chip with both high frequency (HF) and ultra-high frequency (UHF) communication interface was launched in 2015. In this text I will take a closer look at the quality aspects of dual interface tags: How do you verify that each tag produced meets its specification?

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…

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?

How to Optimize the Cost of Quality for UHF Tags?
Published on by

When talking about high-end RFID performance testing solutions, I sometimes face the situation, where my customer is struggling to find room for the investment in their budget. After some return on investment (ROI) calculation the situation typically looks much brighter.

If we look at the overall quality cost structure in UHF tag manufacturing, I would dare to claim that in many cases even a single batch of poor quality can justify the ROI for decent RFID test equipment. The challenge here is though that the costs of being able to provide good and consistent quality are directly addressed to the production, whereas the costs induced from poor quality are inconspicuously scattered all around the corporate structure.

Where do I base the claim? Let me show you!

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?
