As a gathering place for daily necessities, supermarkets bring convenience to people's lives, but also face the universal problem of theft. How to solve this problem, the following editor recommends that you use supermarket anti-theft labels.
1. The classification of anti-theft hard tags is divided into frequency, which can be divided into radio frequency (8.2MHZ) hard tags and acoustic magnetic (58KHZ) hard tags. Match the frequency of the anti-theft door installed at the entrance of the passage. When the anti-theft hard tag of the same frequency passes through the passage, it will trigger the anti-theft door alarm. According to the internal structure, the shape of the built-in coil of the radio frequency hard tag is generally more round or square. The size of the coil depends on the size of the tag. The larger the coil, the more sensitive the detection, the wider the detection distance, and the easier it is to be detected when passing through the channel. Acousto-magnetic hard tags generally have a built-in magnetic rod that is more "long" or "rod". The size of the magnetic rod depends on the size of the label. The larger the magnetic rod, the more sensitive the detection and the wider the detection distance. When passing through the channel The easier it is to be detected.
2. How to use anti-theft hard tags
Both radio frequency hard tags and acoustic magnetic hard tags can be used with anti-theft nails or anti-theft wire ropes. Lightly buckle the anti-theft nails or anti-theft wire ropes on the anti-theft hard tags through the product and do not fall off. They can be opened with a lock opener. Some The anti-theft hard tag can be used directly if it comes with an anti-theft nail or steel wire rope.
