Impinj launches long-range field rewritable RFID



     The US-based ''self-adaptive Silicon'' producer, Impinj Inc., has announced its first long-range field re-writable RFID tag product, named ''Zuma'', which will be ready for shipment in June 2004.

     Zuma enables RFID users to write data to tags at long range, enhancing the functionality and value of RFID deployments in the supply chain. Available immediately for pilot programmes to validate performance, functionality, and compliance with EPCglobal standards, Zuma uses tags that employ Impinj''s patented Self-Adaptive Silicon technology to provide the following benefits:


     Long range writability, which makes field tag writing viable and cost-effective.
     Lockable, rewritable memory, which improves supply chain efficiency by providing accurate, secure data when and where required.
     A ''kill'' feature, which addresses consumer privacy concerns by providing the ability to quickly and permanently destroy tag-based information.

     "The Zuma system will turbo-charge an already exciting market," anticipates Dimitri Desmons, Impinj''s director of RFID products. "The response from customers who have had early access to it has been extremely positive."

     Zuma''s long-range rewritability enables OEMs to develop RFID pilot deployments quickly and cheaply because their implementations can more closely mimic existing barcode systems. Better still, information can be written to the same tag at any point in the supply chain, where additional bar code labels are typically used today. This article is copyright 2004 UsingRFID.com.

     Many applications such as passport control, transportation and industrial automation have already benefited from the read/write features of older RFID systems. "Reliable, field re-writability will be a key feature for the future of RFID adoption," said Christopher Boone, programme manager for retail/wholesale/CPG research at IDC. "Using tag memory to access localised data from tags and to write new data to tags at the edge of the RFID network will provide additional value."
