Abstract
A set of wireless devices can be coupled together using a radio frequency identification (RFID) system. The system includes an RFID writer for writing a unique identifier to an RFID tag stored in a transmitter device. The unique identifier can then be used to identify a wireless signal sent from the transmitter device to a receiver device. The receiver may also include an RFID tag, and the two devices may share a secret encryption key for use in creating an encrypted link between the transmitter and receiver. Virtual links may also be established at a distribution center by writing an address through a closed box into each device RFID. One or more RFID writers may be used to verify the identifier written to the RFID tags, carry out quality control checks, and track products to prevent inventory leaks and verify that sold products are certified.
