Impinj, NEC TOKIN and NEC Partner to Deliver High Performance Gen 2 RFID Readers in Japan

Derivatives of EPCglobal-Certified Speedway(TM) Reader Meet Japanese Radio Frequency Regulations

Impinj, Inc., the number one supplier of Gen 2 Radio Frequency Identification (RFID) chips and readers, and NEC TOKIN Corporation, located in Sendai City, Japan, today announced an agreement to co-develop RFID readers for the Japanese market.

Under the agreement, Impinj will adapt its Speedway(TM) Gen 2 RFID readers to conform to Japanese radio frequency regulations. NEC TOKIN will develop and market its own brand of RFID reader products based on the Speedway platform for the Japanese market. The agreement also includes a partnership with NEC Corporation, NEC TOKIN's parent company. NEC will offer the "Powered by Impinj" readers, with NEC's "RFID Manager" middleware, as part of its systems integration business. The middleware manages the electronic product code (EPC) information streaming from the readers and sends the data on to warehouse and enterprise management systems. The companies' first joint deployment will be an installation at NEC's Personal Products Co., Ltd., the PC manufacturer, in Yonezawa.

Impinj's Speedway reader received the EPCglobal Gen 2 standard certification mark and has been successfully installed in large North American retail and distribution environments that require RFID technology to improve supply chain efficiency. Speedway exhibits unprecedented levels of performance and was recently demonstrated to support item-level RFID tracking for pharmaceuticals, apparel, CD/DVDs and many other high value products.

"NEC TOKIN is very pleased to be able to make Impinj's world-class RFID reader technology available to Japanese customers," said Takeji Takeda, General Manager of Access Devices Marketing Division at NEC TOKIN Corporation. "RFID technology is very important to many leading retail and product companies and we look forward to helping those customers, beginning with NEC Personal Products Co., improve their supply chain efficiency with new RFID products."

"Impinj's collaboration with NEC TOKIN is very exciting for the global RFID market," said William Colleran, president and CEO at Impinj. "Our partnership allows us to make the highest performance and highest quality RFID readers available to Japanese companies in a number of important market sectors."
