EAS AM Soft Label AM005

Working method of anti-theft system

Electronic labels are divided into anti-theft soft labels and anti-theft hard tags. Anti theft soft labels are also called anti-theft stickers, and anti-theft hard tags are also called anti-theft buckles, which are often used in clothing and supermarkets. The cost of anti-theft sticker is low, which is directly adhered to the “hard” goods, and the soft label can not be reused; The one-time cost of anti-theft buckle is higher than that of soft label, but it can be reused. The anti-theft buckle must be equipped with a special detacher, which is mostly used for soft and penetrating articles of clothing. Most deactivators are non-contact devices with a certain decoding height. When the cashier checks in or bags, the electronic label can be decoded without touching the degaussing area. There are also devices that combine the decoder and the laser bar code scanner, so that the commodity collection and decoding can be completed at one time to facilitate the work of the cashier. This method must cooperate with the laser bar code supplier to eliminate the mutual interference between the two and improve the decoding sensitivity. The detector is generally a detection system device at the entrance and exit of the mall or the cashier channel. After receiving the correct payment from a customer for a commodity, the cashier can authorize the commodity and legally leave a designated area by neutralizing the label pasted on the commodity. When the uncoded goods are taken away from the mall, the alarm will be triggered when they pass through the detector device (mostly door shape), so as to remind the cashier, customers and mall security personnel to deal with them in time.

Anti theft detection steps

• 1. Attach the anti-theft soft label to the commodity.
• 2. Install EAS Anti-theft Antenna Systems at the outlet channel or cashier channel of the mall.
• 3. After payment, the goods pass through a special deactivator to invalidate the label decoding or unlock and remove the label.
• 4. When unpaid goods (with labels) pass through the exit, the doorway detector detects the labels and sends an alarm to intercept the goods from going out.

The so-called acoustic magnetic system (AM) uses the resonance phenomenon generated by the tuning fork principle to realize almost zero false alarm operation. When the frequency of the transmitted signal (alternating magnetic field) is consistent with the oscillation frequency of the acoustic magnetic label, the acoustic magnetic label is similar to the tuning fork, which will cause resonance and produce a resonance signal (alternating magnetic field); When the receiver detects 4-8 consecutive (adjustable) resonance signals (once every 1 / 50 second), the receiving system will send an alarm.
The acoustic magnetic system is characterized by high anti-theft detection rate, almost zero false alarm, no shielding by metal tin foil, good anti-interference and wide protected outlet (the maximum width of a single system can be protected is 4m).

Precautions for the use of anti-theft labels in supermarkets

• 1. Before selecting the supermarket anti-theft label, first determine the frequency of the anti-theft door. (acoustic magnetic, radio frequency, electromagnetic)
• 2. After confirming the frequency, select the supermarket anti-theft label of the corresponding frequency.
• 3. The frequency of Dr anti-theft label is acoustic magnetic (AM), disposable and can not be reused.
• 4. Special acoustic magnetic degausser shall be used for degaussing small and easy to steal goods pasted in the mall.
• 5. Do not stick the supermarket anti-theft label on the place where the goods are printed with important instructions. If the anti-theft label is forcibly removed, the surface of the goods will be damaged.
• 6. Dr anti-theft label can be used on most metals and is not easy to be shielded by supermarket metal shopping cart.
