摘要
Methods and systems are provided for controlling an RFID emission within an environment including a sensitive object whose operation may be affected by RFID emissions above a particular strength. An RFID reader of the system is configured to emit a reader signal, while a host is associated with the RFID reader and configured to define the strength of the reader signal. A guard tag is configured to receive the reader signal and, upon receiving the reader signal, emit a return signal to be received by the RFID reader. The host is further configured to, upon the RFID reader receiving the return signal, decrease the strength of the reader signal and/or change the direction in which the reader signal is emitted, preferably until no further reader signal is received by the RFID reader.
