How well do you know your RFID tags?
Testing, Measurement, and Encoding Systems for RAIN RFID and NFC.


NFC Tapping - Smartphone Performance Comparison
Published on by

中文版 Chinese version I recently visited an NFC forum meeting where I listened to industry presentations and discussed with many NFC industry experts. User experience, user expectation, and physical level interoperability of various NFC devices came up frequently. This prompted me to finish this article, a draft version was written already while ago. I tested a few smartphones for NFC tapping user-friendliness and dug a bit deeper on the factors affecting the user experience. Three NFC Application Types When I think of NFC, I think of three very different application types and different experiences with them. Smart card: Think of a hotel ... Read more →

Using TIPP Tagged Item Performance Protocol Outside Retail
Published on by

RAIN RFID is being adopted increasingly in several industries such as automotive manufacturing, healthcare, and pharma. Because of the growing number of implementations, there is an increasing need for a solution that helps to scale up the implementations. One of the bottlenecks seems to be specifying RAIN tag performance in a way that enables the use of tags from several manufacturers in a system. Need for performance specification or for a method to classify tags comes up more and more frequently in industry meetings. The good news is that pioneering industries have solved these questions earlier, and there are working solutions ready for adoption.

Testing Against RFID Immunity Makes Medical Devices Future Proof
Published on by

Tightening cost, quality of care and efficiency requirements are some of the drivers that highlight healthcare as one of the strongly growing RFID application areas. RFID improves patient safety, raises operational efficiency and reduces shrinkage. To remove possible RFID related risks and uncertainties, a new test standard was created, describing methods for testing Medical Electric Equipment and System Electromagnetic Immunity against RFID readers.

When Buying Tags - Ask the Right Questions
Published on by

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.

RAIN RFID Speeds Up Season Cycles of Apparel Value Chain
Published on by

I had the pleasure of attending a networking event of Americas Apparel Producers’ Network - AAPN a few weeks ago. The presentation topics and discussions ranged from lighter reminiscences of past gatherings to hard core statistics around today’s retail.

As a take-away I thought a grim view was painted of the main stream apparel value chain of brand owners and retailers. This traditional apparel retail value chain seems slow and rigid; and is definitely challenged by online sales and vertically integrated fast fashion companies. Recently I’ve also heard presentations from a couple of vertically integrated retail chains – with focus on their RAIN RFID projects. Those stories painted a more positive view of the retail value chain.

Read on to see how these two opposite forecasts might merge.

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, UHF RFID, EPC RFID, ... - Confused by the Different Names?
Published on by

I am frequently lecturing to RFID users and technology providers about quality and performance in RFID. Every now and then a question about the terminology comes up. RFID technology has developed through several paths and as a result there are a lot of names and definitions for RFID. A beloved child has many names, says a Finnish proverb. Understanding the different points of view in naming and the origins of the terminology help to understand the many names.
