The acousto-magnetic anti-theft system consists of three parts: One is the detector. Including transmitter and receiver two parts. The basic principle is to use the transmitting antenna to emit an alternating magnetic field to form an induction area between the transmitting antenna and the receiving antenna. Use the resonance principle of electromagnetic waves to search for valid tags within a specific range (that is, without decoding by the decoder).
The label exists), when a valid label appears, the alarm is triggered. The second is acousto-magnetic tags. It is accurately cut into the size of 58kHz from the disorderly arranged amorphous metal, which resonates with the polarizer through entering the detection area and reflects to the receiving support. The third is a decoder, which is a non-contact device that fails to decode soft tags.
When the cashier checks the cash, the electronic tag can be decoded without touching the degaussing area; or the integrated device of the decoder and the laser barcode scanner can complete the collection and decoding of the goods at one time.
