9. An RFID tag detection system comprising:
-
an antenna arranged to transmit a tag request and receive a tag response; a memory comprising a set of executable instructions; and a processor communicatively coupled with the memory and the antenna and arranged to execute one or more instructions of the set of executable instructions, execution of the one or more instructions by the processor causes the processor to cause the antenna to transmit a predetermined number of RFID tag requests and to determine that an RFID tag is either a not of interest tag based on receipt of tag responses from the RFID tag less than the predetermined number of RFID tag requests transmitted or a tag of interest. - View Dependent Claims (10, 11, 12, 13)
