Vehicle RFID Tags - Big Benefits with Some Challenges
Published on by

Electronic Vehicle Identification (EVI) tags are a perfect match to RAIN RFID (UHF RFID) technology. Once a vehicle is tagged, the possibility to identify the vehicle remotely enables a lot of applications and services. While the vehicle tagging is of high interest, it is not the easiest task. In the past few months I have worked with some vehicle tagging projects and learned that the application requires some special attention from technology providers.

RAIN RFID Tag Read Range: Opinion or Fact?
Published on by

Creating a tagging solution for passive RAIN RFID tags to a particular application starts with understanding the application specific requirements. That involves plenty of process engineering, but also typically discussions around the expected read range between tagged items and reader antennas. The read range is impacted by several factors and many start the cooking process by looking at the properties of RAIN RFID tags.

Battery Assisted Passive (BAP) Tags - Do You Know Your Reader Receiver Sensitivity?
Published on by

One of my customers in Taiwan is developing battery assisted passive (BAP) tags. He called me recently and asked why the read range that they reach with their RFID reader is only a quarter (1/4) of the distance that they measure with their Tagformance RFID measurement system. I answered him with another question: “Do you know your reader receiver sensitivity…?”

RFID, Love or Die
Published on by

Dear reader, my name is Lluis Bueno, and I love RFID. Do you? I belong to the Spanish company NextPoints, and I have met hundreds of professionals and companies working in the RFID market without any passion for the technology… and most of them are not working in the RFID market anymore. So, why is love required for RFID business to survive?

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?

Tagged-Item Grading Helps Retail UHF RFID Projects
Published on by

Retail and the retail supply chain are among the biggest 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 different applications: logistics tracking, inventory count, RFID EAS, POS, and so on. I have been involved in a number of 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?

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?

Why UHF RFID Tag Developers Should Use Wide Band Performance Testing
Published on by

RFID reader frequencies are controlled by governments and limited to narrow frequency bands that vary around the world. When the performance of an 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 good visibility into UHF RFID tag performance. Read more about wide band testing and what it reveals from UHF RFID tag performance!
