Abstract
A radio frequency identification (RFID) system used to perform electronic article surveillance comprises a RFID tag and a RFID reader. The RFID tag is affixed to an object, and the RFID reader, having a plurality of antennas, is in radio frequency (RF) communication with the RFID tag. The plurality of antennas are arranged to have a spatial relationship with one another to monitor and communicate with the RFID tag such that a likelihood of a security breach of the RFID tag is determined. Determining the likelihood of the security breach is based, at least in part, on a signal strength of a read of the RFID tag at each antenna relative to the plurality of antennas.
