1. A radio frequency identification (RFID) tag system, the system comprising:
- a coupler/controller subsystem that wirelessly receives and transmits at least one user signal and at least one master signal; and
a memory electrically coupled to the coupler/controller subsystem, wherein the memory comprises a user portion for storing information contained in the at least one user signal and a master portion for storing information contained in the at least one master signal, and the master portion of the memory is unalterable by a user wherein the coupler/controller subsystem comprises a coupler having double-tuned electro-magnetic tank that is electrically coupled with two high-resolution frequency-filters, an antenna, a user controller and a master controller, wherein the antenna is electrically coupled to the coupler, the coupler is electrically coupled to the user controller and the master controller, the user controller is tuned to a user frequency that is used to transmit and receive the at least one user signal, the master controller is tuned to a master frequency that is used to transmit and receive the at least one master signal, and the master frequency is different from the user frequency.
