One practical advice is to only hold the tag close to the reader that is being written. In such cases, the tag must be written again or, for example, the tag can be moved closer to the reader to improve the communication link. It is also possible that a specific tag is lost from the reader’s field and doesn’t reply at all. If a tag doesn’t have enough power to perform writing it may send back a message indicating that the power level is not sufficient or that writing was only partially done. The desired outcome is, of course, that the writing is successful. The writing procedure has several possible outcomes. Without singulation, the write operation is performed on a randomly selected tag. By singulating a specific tag, you can be sure that you are writing on the correct tag. When initializing the writing procedure, the tag in question is singulated against the desired memory bank contents, usually the EPC bank. We start out with discusses the actual tag writing.

This article discusses matters related to UHF RFID tags and tag writing, as well as provides tips to how to succeed in both writing and reading UHF RFID tags.Ī practical guide to UHF RFID tag writing This optimizes the product benefit as well as data security.Once the decision to adopt RFID in the company’s operations has been made, there are a number of things that needs to be considered. It is therefore more efficient to store only the EPC on the chip and store additional information in a cloud. At the same time, a high read range is needed for pulse readings. "The trend is to keep RFID tags as small as possible and to embed them discreetly in products.
"In the textile industry, it is not necessary to store additional data on the chip," explains Emmanuel Arène. Embedded in the product, the tag is not visible from the outside." High-performance and Miniaturized RFID Tags for the Textile Industry "The tag withstands high temperatures and multiple wash cycles. The design significantly increases flexibility," Emmanuel Arène points out. "The E-Thread™ tag is particularly robust, as the tag does undergo the production process and remain functional until the end of the product's life. RFID integration takes place directly during the manufacturing process of the end products. The design of E-Thread™ tags enables UHF RFID integration into textiles and clothing, ropes, cables, hoses, and tubes. Track & Trace Solutions for the Entire Product Life Cycle However, the tag itself is far more flexible and robust than conventional RFID tags. The result: reading and writing the tags is possible with standardized antennas and readers. The impedance of the antenna matches the chip, providing a superior reading performance even in harsh customer environments. The base chip is adapted by connecting the antenna directly to the chip in a proprietary assembly process.

These are compliant with international requirements in terms of protocols and ISO guidelines. "The form factor of the E-Thread™ tag is very different from conventional tags or labels," explains Emmanuel Arène, Co-founder, Chairman of the Board and CEO, Primo1D. The storage capacity is 96 to 128 bits according the the EPC Gen2 V2 protocol standard. This miniaturized UHF RFID tag is then wrapped in a textile yarn.
E-Thread™ offers a unique design for RFID tags: the chip is directly connected to the two strands of the antenna.
