Impinj Extends GrandPrix Gen 2 RFID Solution to Item-Level Tagging

First RFID System to Enable One Infrastructure For Case and Item Tagging Worldwide

SEATTLE, Wash., February 21, 2006 – Impinj, Inc., the fabless semiconductor company whose patented Self-Adaptive Silicon® technology enables its high performance radio frequency identification (RFID) products, today announced the extension of its GrandPrix™ Ultra High Frequency (UHF) Gen 2 solution to include item-level tagging capability. Responding to increased demand from the global retail supply chain and other high-growth markets, Impinj has enhanced GrandPrix for tracking pharmaceuticals, apparel, CD/DVDs and many other high-value products.

Conforming to EPCglobal’s Gen 2 standard, GrandPrix is the first RFID system to provide a single infrastructure suitable for tagging items, cases and pallets, thus simplifying RFID installations and reducing system implementation costs without sacrificing system performance or functionality. Powered by Impinj’s industry-leading Monza™ Gen 2 tag chip and Speedway™ reader with monostatic antenna technology, the GrandPrix item-level tagging solution also comprises a suite of patented, small-footprint tag antennas optimized for challenging item types or stocking conditions. For example, GrandPrix includes customized tag antennas for garments, DVDs and other stackable items, and items containing liquid or metals.

“Impinj is the first company to bring all the benefits of Gen 2 RFID to item-level tagging with tags as small as 9.0 mm,” said Dr. William Colleran, president and CEO of Impinj. “Retailers want to implement RFID tags on items, cases and pallets using a single RFID infrastructure at all of their facilities worldwide, and we are delighted to be the first RFID systems provider to deliver the GrandPrix solution that meets all of those requirements.”

Impinj has shipped more than 50 million Monza RFID chips, key components of the GrandPrix solution, to companies worldwide.

Impinj will demonstrate its GrandPrix solution for item-level tagging at the RFID World conference in Dallas, on February 28 and March 1, 2006. For more information, visit www.shorecliffcommunications.com/rfid06/.
