Acoustic-magnetic labels are used for preventing thefts of certain goods in stores, hypermarkets and supermarkets. Typically, protective labels are flat, that allows them not only stick to the surface of goods, but also place inside the package. In appearance, they don't not differ from usual labels (on them can also been applied false bar code, etc.), which provides a high-grade security. Such acoustic-magnetic labels are disposable, remove them without damage is very difficult, so at the cash register such labels are simply deactivated by special equipment. There are different types of anti-theft labels which are used in stores, acoustomagnetic, radio frequency, etc. In any case, such labels will not allow to stay unnoticed when carry unpaid goods outside the store.
