ABSTRACT:
In one embodiment, a system for communicating with an RFID tag is provided that includes: a capacitive encoder adapted for placement in proximity of the RFID tag and operable to transmit a first operating signal to the RFID tag for communicating with the RFID tag; wherein the capacitive encoder is further operable to transmit to the RFID tag a second operating signal adapted to excite the RFID tag such that RF radiations from the RFID tag to adjacent RFID tags are nullified.
