How do supermarkets use soft labels and hard tags to prevent thieves? Many of us know that there is an EAS system at the entrance of the supermarket. When we accidentally take unpaid items out of the supermarket, we will sound a harsh alarm. So, How is the alarm occured? Let us briefly introduce the composition of the electronic EAS system.
The supermarket EAS system is divided into soft labels system and hard tags system. The soft labels system is consisting of a detection antenna (composed of a transmitter and a receiver), a soft label and a decoder. When using this system, you can protect the goods by simply attaching a soft label to the item you are selling. Once someone has carried the tagged item out of the supermarket without payment, when the product passes through the detection channel, the detection antenna will detect the signal of the tag attached to the product, and an alarm sounds.
The hard tag system is different. It consists of a detection antenna, a detacher and various hard tags. When using the hard tag, buckle it on the product. Note that the hard tag cannot be removed by hand. After the customer pays, the salesperson can remove it with a detacher, otherwise it will be the same as the soft label. When the product with the hard tag passes the detection antenna, the antenna will also sound an alarm. Hard tag systems are more commonly used in supermarkets for all types of clothing, or shoe and hat stores and specialty stores. Hard tags are different from soft label, they can be used over and over again, saving money and convenience.
