Anti-theft tags belong to EAS technology and are used to identify anti-theft soft tags or anti-theft hard tags (reusable) through detection systems placed at the entrances and exits or cashier passages of shopping malls and supermarkets.
If the soft label is not degaussed or the hard label is not taken, the alarm device will issue an alarm when passing through the system.
Supermarket anti-theft soft tags and supermarket anti-theft hard tags use the principle of magnetic induction to prevent theft.
