one of the commodity security measures widely used in the large-scale retail industry. EAS system is
mainly composed of three parts: detector, deactivator and electronic tag. Antenna is installed in the exit of

alarm. Therefore, when customers enter the store, it is easier for you to make eye contact with them and
