System and method for detection of near moving radio frequency identification (RFID) tags

A non-transitory computer-readable device having instructions thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:

• determining, by a processor of an EAS system, a chatter score of a RFID identification of an RFID tag that generated a quantity of RFID readings above a predefined threshold at one or more RFID readers, wherein the chatter score corresponds to a metric representing RFID tag activity;
• selecting, by the processor of the EAS system, the RFID identification based at least in part on the chatter score being below a chatter score threshold;
• determining, by the processor of the EAS system, that the RFID identification corresponds to a RFID tag in motion;
• and
• triggering, by the processor of the EAS system, an alarm based on a determination that the RFID tag identified by the RFID identification is not authorized to leave a controlled area associated with the one or more RFID readers.

An electronic article surveillance (EAS) system, comprising:

• a plurality of reader devices;
• a RFID tag associated with a RFID identification;
• a memory storing instructions thereon;
• and
• at least one processor coupled with the memory and configured by the instructions to:
• determine, by a processor of an EAS system, a chatter score of a RFID identification of an RFID tag that generated a quantity of RFID readings above a predefined threshold at one or more RFID readers, wherein the chatter score corresponds to a metric representing RFID tag activity;
• select the RFID identification based at least in part on the chatter score being below a chatter score threshold;
• determine that the RFID identification corresponds to a RFID tag in motion;
• and
• trigger an alarm based on a determination that the RFID tag identified by the RFID identification is not authorized to leave a controlled area associated with the one or more RFID readers.
