How to choose a good quality acoustic magnetic anti-theft tag?

Acoustic magnetic anti-theft tags are widely used for the anti-theft of goods in supermarkets and retail stores. The quality of the tags directly affects the anti-loss efficiency of shopping malls. At present, there are many kinds of products in the domestic market. How to choose a good quality acoustic magnetic anti-theft tag? We believe that it is necessary to choose from the following three aspects:

• 1. Reliable alarm performance
  Alarm performance, as the most important indicator of acoustic magnetic anti-theft tags, mainly depends on the antenna detection distance and frequency. Therefore, in the procurement process, products with accurate frequency and good alarm distance should be selected.
• 2. Good demagnetization performance
  The typical application scenario of acoustic magnetic anti-theft tags requires that the product has good alarm performance before passing through the cash register, and no longer has alarm capability after being processed by demagnetization equipment. Therefore, when choosing, you should choose products with good anti-attenuation ability, that is, it is not easy to demagnetize during storage, but can completely lose the alarm capability after being processed by standard demagnetization equipment.
• 3. Stable quality
  Acoustic magnetic anti-theft tags are used in large quantities for a long time in the retail process, so the stability of batch products and the stability of product performance between different batches are particularly important. Therefore, when choosing a partner, priority should be given to manufacturers with a high degree of production automation, large supply volumes, and advanced technology.
