Abstract:
A passive remote programmer system for an induction type RFID reader having RF sensing means operatively connected to a microprocessor for reading tag identification data of RFID transponder tags powered by a sensing field of the reader and for verifying said identification data against stored identification data thereby to recognize the presence of authorized tags, said programmer system comprising:a hand held programmer unit housing an antenna, a plurality of dedicated RFID transponder tags each having a unique tag code, and a keypad having a plurality of keys each selectively operable for connecting a corresponding one of said dedicated RFID transponder tags to said antenna thereby to power the selected tag by induction in the said sensing field and enable the unique tag code of the selected tag to be read by the said RFID reader; andprogram means operative in cooperation with said microprocessor for executing a first action in response to recognition of tags presented through mere proximity to the reader in said sensing field, and a second action different from said first action in response to recognition of a said dedicated RFID transponder tag powered by operation of a key on said keypad, such that response of said RFID reader to said tags presented through mere proximity may be modified by operation of said keys on said keypad.
