Abstract
A method for creating an enhanced RFID tag. A longer range RFID tag and a relatively shorter range credential are proximately co-located in the same container. The longer range RFID tag is cryptographically bound to the shorter range credential by storing, on the longer range tag, signed data which includes indicia of the shorter range tag. The longer range RFID tag requires authorization via an authentication server to grant access to data stored in the enhanced RFID tag.
