Abstract
In a bi-directional embodiment, an authorization transpondercoupled to the mobile devicetransmits an interrogating message, which includes a UIDassociated with the mobile device, to a nearby wireless key. The wireless key compares this received UIDwith the one or more UID'sstored on the wireless key, and if a match is detected, sends the wireless key's UID or encrypted variant thereof to the interrogating authorization transponder. On receiving the UID from the wireless keyand determining that it matches the authorization transponder UID, a command is sent from authorization transponderto mobile deviceenabling some or all operations of mobile device. In a uni-directional embodiment, one or more UIDare periodically transmitted from a wireless keyto a receiverin authorization receivercoupled to the mobile deviceto be controlled, wherein the UIDfrom the wireless keyis compared to a UIDassociated with the authorization receiver. On receiving the one or more UIDfrom the wireless keyand determining that it matches the authorization receiver UID, a command is sent from authorization receiverto mobile deviceenabling some or all operations of mobile device. Yet another embodiment of the invention controls access to data on a passive mobile device, such as that data stored on the magnetic stripe of a transaction card, by authorizing the card readerto read additional card data when the UID on the card matches a UID of a nearby wireless key. Upon reading a UID from the card, the card reader interrogates a wireless key for its UID, and compares these two UID's. If the two UID's match, authorization for further data transfer from and to the card is given.
