OPENTAG is an RFID development platform for advancing ubiquitous electronic tagging of items and people. With OPENTAG, we break through the barrier of application-specific and proprietary RFID product engineering by developing our own tag and associated firmware. An OPENTAG can adapt to varying demands as a tagged item moves through its life cycle from manufacturing to supply-chain to retail to consumer to disposal. OPENTAG is security conscious and privacy friendly.
