Why do Japanese supermarkets seldom use anti-theft systems but use adhesive tape to identify sold goods?

Adhesive tape is low in cost. The anti-theft system is composed of detection access control, anti-theft label consumables, and cashier decoding equipment. Instead of labeling and alarming, it is used as a complete set. Both Walmart and Watsons use the acoustic magnetic system (58KMz) in developed countries. Relatively high

The other is that the anti-theft label consumables are relatively the most expensive. The use effect and equipment stability are the best. Most supermarkets in China use radio frequency systems. This system has been around for many years. There are many disadvantages, but the cheapest, use this clothing store. It’s still good, the supermarket! Product coverage is around 60%

　　 Another supermarket site is not well managed, it is easy to cause false alarms.
