Supermarkets have added anti-theft features, making it impossible for thieves to make a move
Abstract：The anti-theft goods in the supermarket were stolen. Many supermarkets use supermarket anti-theft tags. However, based on the detection signal methods they employ, these tags can be roughly classified into systems such as radio systems and electromagnetic wave systems.

(Acoustic-Magnetic System)
The tuning fork can only cause resonance when its oscillation frequency is the same. The Acusto Magnetic system precisely applies this physical principle to achieve almost zero false alarms. When the acoustic-magnetic system label fixed on the product enters the detection area of the system, resonance occurs, but an alarm is only triggered after the receiver receives four consecutive resonance signals (once every 1/50 second).
The characteristics of the sound-magnetic system are high theft detection rate, almost zero false alarms, good anti-interference performance, and the protected exit width can reach 3.5 meters. It has both soft and hard types of theft tags, and can protect most types of goods in the shopping mall. Moreover, it can be repeatedly demagnetized, and the system can still work normally even when placed beside the POS cash register.
The sound magnetic system includes various types such as vertical system, channel system and concealed system. There are over 10 different models available for selection, and it can be widely applied in department stores, supermarkets, specialty stores, audio-visual stores, grocery stores, pharmacies, and also in office buildings and other environments.
(2) Radio system
The radio frequency (RF) system uses radio waves as the transmission and reception signals. It detects electromagnetic waves within the frequency range of 7.4 - 8.8 MHz, with a center frequency of 8.2 MHz. It causes interference at 8.5 MHz due to the tags, thereby triggering an alarm. The major advantage of the radio frequency system is that it has a very low system cost and is easy to install. However, because its anti-theft tags are of the ring coil type, the system is susceptible to interference from some items, such as electronic products like cash registers and metal objects, which may cause false alarms or non-alarm situations.
The radio system has two types of labels - soft and hard - which can protect most of the items in the shopping mall. The distance between the two supports should generally not exceed 0.9 meters and is usually used in shopping malls with only one entrance and exit. The radio system comes in two types - vertical and channel - and is used to protect department stores, clothing stores, supermarkets, etc.
