It consists of detection antenna (transmitter and receiver), decoder and soft tag. When in use, as long as the soft label is attached to the goods, the purpose of protecting the goods can be achieved. When someone tries to steal goods with labels, after the goods pass through the detection channel, the detection antenna will detect the label signal on the goods, and at the same time send out an alarm sound to remind the security personnel in time, so as to achieve the purpose of anti-theft. When purchasing normally, the clerk decodes the anti-theft label after checking out, and the customer can pass "safely". The soft label system is mainly used in shopping malls such as books, audio-visual products, washing products and cultural goods, and the soft label is disposable.

Hard tag system: consists of detection antenna, lock opener and various hard tags. When in use, the hard tag is buckled on the commodity (it cannot be removed by hand), and after the customer pays, the salesperson will remove the hard tag with the lock opener, otherwise, when the commodity with the hard tag passes through the detection area of the detection antenna, an alarm will also be given. Hard label system is widely used in all kinds of clothing, shoes and hats stores and specialty stores. Hard labels can be reused.
