Abstract
Methods and systems of processing transponder signals received from transponders to identify the transponders are provided. A first signal including a first code and a first identifier may be received from a first transponder. The first identifier is written to the first transponder by an RFID writer when the first transponder is placed proximate to the RFID writer, and the first identifier is used to associate transponders with a first user. A second signal including a second code and the first identifier may be received from a second transponder. The first identifier is also written to the second transponder by the RFID writer when the second transponder is placed proximate to the RFID writer. The first and second transponders are associated with the first user based on receiving the first identifier from both the first and second transponders.
