Abstract: An example disclosed method for authenticating a radio frequency identification (“RFID”) tag includes receiving a first signal including a first transponder identifier associated with the RFID tag; receiving a second signal including a second transponder identifier, wherein the second transponder identifier is associated with a different transponder than the first transponder identifier; and determining, with circuitry, whether the second transponder identifier is associated with the RFID tag.

Abstract: An encoding module and related systems and components are provided. The encoding module includes a plurality of encoding elements arranged in an array of columns and rows and one or more switching elements configured to selectively connect the encoding elements to a reader. The connection of the encoding elements may be based on the location of a targeted transponder disposed among multiple adjacent transponders to ensure the selective communication with the targeted transponder only. The module is configured for various types and locations transponders to be used within a system, such as a printer-encoder. Each encoding element may include a loaded conductive strip comprising a loop shape portion and a shield that corresponds to the loop shape portion. In another embodiment, an access control system having an encoding module with the plurality of couplers and an access card having a plurality of transponders corresponding to the couplers is provided.
