How does the supermarket use soft label and hard label to prevent thieves?

Many of us know that there are anti -theft systems at the entrance of the supermarket. When we accidentally bring the unpaictable goods out of the supermarket, we will sound harsh. So, what did this siren sound? Let's briefly understand the composition of the commodity electronic anti -theft system today.

The EAS system, which is practical for supermarket anti -theft systems, is divided into soft label system and hard label system.

The so -called soft label system is a anti -theft system composed of detecting antennas (composed of transmitters and receivers), soft labels and decoders. When using this system, as long as a soft label is attached on the selling goods, the purpose of protecting the product can be achieved. Once someone brings the labels without paying out of the supermarket, the product will detect the signal of the label posted on the product when the commodity is detected through the detection channel, thereby issuing a alarm sound.

When we buy goods normally, the salesperson will decode the anti -theft label after checkout, and this product can safely detect the antenna. This label is used at one time and is mainly used in shopping malls such as large supermarket cultural supplies.

The hard label system is different. It is composed of detecting antennas, unlocking device and various hard labels. When using hard labels, it is deducted on the product, and the hard label cannot be taken down with the hard label. When the customer pays, the salesperson can use the unlocker to remove it, otherwise the same as the soft label, when the product with a hard label is detected by the antenna, the antenna will also make alarm sound. The hard label system is more commonly used in various types of clothing in supermarkets, or shoe, hat shops and specialty stores. Different things from hard labels and soft labels can be repeatedly used repeatedly, saving money and convenient.
