Abstract
A switchable RFID tag comprising at least one RFID code circuit disposed on an adjustable member being adjacent to an antenna; wherein the adjustable member is arranged to be manipulated to move the at least one RFID code circuit into a communication position whereby the RFID code circuit is coupled to the antenna; and into an inactive position whereby the RFID code circuit is uncoupled from the antenna.
Claims24
A switchable RFID tag comprising
- at least one RFID code circuit disposed on an adjustable member being adjacent to an antenna;
- wherein the adjustable member is arranged to be manipulated to move the at least one RFID code circuit into a communication position whereby the RFID code circuit is coupled to the antenna;
- and into an inactive position whereby the RFID code circuit is uncoupled from the antenna.
A method for operating a switchable RFID circuit comprising the steps of:
- manipulating a tag plate having a plurality of RFID tags thereon between a communication position and an inactive position, wherein in the communication position, at least one of the plurality of RFID tags is arranged to couple with an antenna for communication, whilst the remaining RFID tags are shielded from the antenna.
