EAS

The electronic item monitoring system EAS is mainly used to prevent theft of goods. The system mainly relies on RFID technology, and RF cards usually have a memory capacity of 1 bit, which can be in two states: on or off. When the RF card is activated and approaches the scanner at the store exit, the system will detect and trigger an alarm. To prevent false alarms, sales personnel may use specialized tools or magnetic fields to disable the RF card or damage its electrical characteristics when the product is purchased. In addition, the EAS system also has various technologies, including microwave, magnetic field, acoustic magnetic, and radio frequency, etc.
