Abstract
The present invention provides for a RFID tag assembly that is suitable for operation with at least one RFID reader assembly. The RFID tag assembly comprises, inter alia, an antenna member for transmitting and/or receiving an RFID signal, and at least one integrated circuit (IC) for processing the RFID signal and which is configured to communicate, alternatingly and sequentially in time, a first signal transmission and at least one second signal transmission, each defined by a plurality of predetermined signal transmission parameters, to the at least one RFI D reader assembly, utilising time-division multiplexing, wherein the at least one first signal transmission differs from the at least one second signal transmission in at least one of said plurality of predetermined signal transmission parameters.
