Systems and methods for using radio frequency identification as an adaptive alarm threshold

摘要

Systems and methods for operating an Electronic Article Surveillance (“EAS”) system. The methods comprise: detecting movement of a plurality of security tags in a facility using Radio Frequency Identification (“RFID”); identifying which security tags of the plurality of security tags are moving towards an exit of the facility or are in a surveillance zone; determining a number of the identified security tags that are coupled to unsold objects; comparing the number to a threshold value; and causing the EAS system to issue an alarm when the number is greater than or equal to the threshold value.
