How supermarkets use soft labels and hard labels to guard against thieves, many of us know that there are anti-theft systems at the entrance of the supermarket, and when we take the goods out of the supermarket out of the supermarket, the sound of a piercing alarm will be sounded. So what did this alarm sound come from? Today we have a brief look at the components of the commodity electronic security system.

In fact, the EAS system used in supermarket security system is divided into soft label system and hard label system.

The so-called soft tag system is an anti-theft system made up of detecting antennas (transmitter and receiver), soft tags and decoder. When using this system, we can achieve the purpose of protecting commodities by putting soft labels on the products sold. Once someone has unpaid goods with labels out of the supermarket, when the goods pass through the detection channel, the detection antenna will detect the signal on the label on the commodity and send out the alarm.

When we buy the merchandise normally, the salesperson will decode the anti-theft tag after checkout, and this product will be able to pass the antenna safely. This label is disposable, mainly used in shopping malls, such as large supermarket cultural products.

The hard label system is different. It consists of a detection antenna, an unlocking device and various hard labels. When you use hard labels, you should buckle them on the goods. Note that hard labels can not be removed by hand. When the customer pays, the salesman can use the unlocking device to remove it, otherwise it will be the same as the soft label. When the product with hard label is detected by the antenna, the antenna will also send out the alarm. Hard labelling systems are more commonly used in all kinds of clothing in supermarkets, or shoes and hat shops and specialty stores. Hard labels are different from soft labels. They can be used repeatedly, saving money and convenience.
