How does the supermarket anti-theft eas system work? [Bohang China]
Regarding commodity barcodes, first of all, the same kind of products, such as a brand and packaged cigarettes, chewing gum, are common, and the barcodes are all the same. If you buy it from another store and bring it into the supermarket, you will definitely be suspected of stealing. This is for sure. Therefore, supermarkets are not allowed to bring such goods into the supermarket, they will remind you to save. How does the supermarket anti-theft eas system work? Regarding the bar code, it does not play an anti-theft role. It is developed to facilitate the management of goods in and out of the warehouse, the monitoring of the circulation field, and the process of financial inventory. It is to track all the goods from production to consumption (sold). process. It is also the role of giving a bar code to a product.
The characteristics of the sound magnetic supermarket anti-theft eas system are high anti-theft detection rate, almost zero false alarm, good anti-interference, and the protection export width can reach 3. 5 meters. There are two kinds of anti-theft labels, both for soft and hard. It can be protected and can be degaussed even if the system works normally even next to the POS cash register. Acoustic magnetic systems include vertical systems, channel systems and concealed systems. There are more than 10 models to choose from. They can be widely used in department stores, supermarkets, specialty stores, audio-visual stores, grocery stores, pharmacies, and also in Office building and other environments.
The radio system (Radio Frequency, RF) uses radio waves as the signal for transmitting and receiving, and the detection frequency range is 7. x~8. x megahertz. The big advantage of the radio system is that the system cost is very low and the installation is convenient. However, because the anti-theft tag is a toroidal coil type, the system is susceptible to interference from some items, such as electronic products such as cash registers, metal objects, etc., causing false positives or failures of the system.
The electromagnetic wave anti-theft system (Electromagnetic System) uses electromagnetic waves as a detection signal. The electromagnetic wave system has a small label, and the label price is also cheap, and the demagnetization can be repeated, but it is susceptible to false alarms due to the influence of magnetic or metallic substances. The width of the protected exit is generally around 0.9 meters. The system does not affect magnetic objects (such as audio tapes, video tapes, magnetic cards)
