Abstract
An RFID reader configures each of a plurality of antennas operating in the RFID reader to operate in one of a first state and a second state, configures each of the plurality of antennas to operate in a first session and a second session and to operate in opposite states in the first session and the second session, and configures adjacent antennas or adjacent groups of antennas to operate in opposite states in the first session and the second session. During operation, each of the plurality of antennas is configured to read an RFID tag within a range of the antenna when a state of the RFID tag for the session in which the antenna is configured to operate matches the state in which the antenna is configured to operate and to switch the state of the RFID tag to the opposite state for each session.
