15. A method of performing radio frequency identification (RFID), comprising the steps of:
-
moving a plurality of resonant structures proximate with an RFID reader, the plurality of resonant structures having a first configuration of locations and frequencies; reading a reader configuration code using the RFID reader, the reader configuration code corresponding to at least one resonant structure of the plurality of resonant structures; retrieving a reader configuration file corresponding the reader configuration code, the reader configuration file containing information regarding a second configuration of location and frequencies; configuring the RFID reader according to the second configuration; reading an identification number using the RFID reader, the identification number corresponding to the first configuration and the second configuration; retrieving client information corresponding to the identification number; and moving the plurality of resonant structures away from the RFID reader. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
