I frequently lecture in RFID training events and every now and then a question comes up from RFID users and system integrators: “When buying RAIN RFID tags, what should we ask from suppliers, and what should we tell to the potential supplier?”. I asked the same question from some RFID tag manufacturers and spiced the answers up with my own experiences and collected the following summary from the answers.Read more →
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?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 →
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!Read more →
Majority of the UHF inlay designers have already come to realize that the right measurement solutions are the key factor for seeing all you need on the UHF inlay performance. There’s not much of those guys anymore, who run around with the tags, checking with a reader how far you can go until the tag can’t be read anymore. Not only is this kind of measurement inaccurate, but also doesn’t give any indication on what kind of changes are necessary for the next iteration in the design. Now I’m happy to see the tag manufacturers are widely adopting the performance testing also in production quality assurance. So from design to production - why should you measure tag performance?Read more →
