Radio-frequency identification (RFID) specialist Impinj has devised a way to make it easier for manufacturers and stores to put RFID tags on shirts, CDs and other consumer items, a move that should please corporations but could raise the hackles of privacy advocates.

The company has extended the reach of its GrandPrix RFID product suite with a new set of tags. GrandPrix consists of a reader, RFID tags and software. The tags used in the current GrandPrix suit are designed to go on pallets and crates. The tags—which rely on electromagnetic propagation for communication—can be read about 30 feet away. The antenna’s length is about 3.5 inches.
