How is the supermarket mall anti theft 20

There are three types of anti-theft measures in supermarkets.

The first type, the magnetic buckle is an obvious buckle on the commodity.

You have to use special tools to take it down.

Second, magnetic nails are things that can be hit on clothes and leather shoes, and they basically require special tools like the above.

The third kind, the soft magnetic barcode is a kind of barcode that is pasted on the original barcode, but he has soft magnetism, and it will be found as soon as he goes out.

Fourth, the inside sees you taking something and follows you and catches you.

In fact, they are all magnetic things, and they will call the police when they pass through that door, and there is no principle, and they are very simple.

If you want to steal it, just remove those external things and take them out carefully.

It's not enough to do less.

How good it is that people can be free.

The metal frame at the door plays the role of alarm, if you buy the goods and do not pay, it will be found, and then the police; There is a product called EAS anti-theft system, which is specifically for store anti-theft of goods, and the anti-theft buckle or label is attached to each product, etc., once you don't pay, there is no decoding, and as soon as you go out of the door, it will be very capable of triggering the alarm sound of the metal frame, so it is best not to use that crooked brain!!

The anti-theft antenna is mainly composed of a transmitting antenna and a receiving antenna, and a radio signal is transmitted from the transmitting antenna to the receiving antenna, so that a radio-magnetic field scanning area is generated between the transmitting antenna and the receiving antenna. The actual principle of the anti-theft tag is an LC oscillation generator (refers to the parallel connection of the inductance coil and the capacitor), which is made with a special process to produce a radio signal like the anti-theft antenna, due to the oscillation of this radio signal, the electromagnetic field scanning area between the anti-theft antenna changes a change, that is, the use of this change to make a signal that can produce an alarm. There are two types of detectors, one is the transmitting antenna and the other is the receiving antenna.

The anti-theft buckle and white paper you said are actually the same principle, with the button signal strong point door distance can be installed, and the "white paper" is actually called "soft tag" to limit the door distance in between.

Fight all hands and give points boss!

。。Supermarket things have labels, and everything has a barcode, they have a barcode scanner, when things into the warehouse, all are magnetized, when you go out to pay, they can be demagnetized, demagnetized things through the metal frame you said will not react, otherwise it will automatically start the anti-theft system

If you want to steal, throw away the package and only take the contents, and you may not be discovered. Haha, I'm guessing ha, whether it's true or not, no one has tried it

You're not afraid of getting caught, are you?

The right way does not go down the wrong path.

Such a situation is better not to be subtle! Ay!

Install anti-theft system software and hardware: such as soft tags, hard tags, burglar alarms. Paste warning signs in places where goods are likely to be stolen:

Shopping mall theft is also a crime, so please don't defy the law. Install monitoring systems, monitors, and display valuable and stolen goods in a more visible position. Train salespeople on anti-theft knowledge.

1. Install anti-theft system software and hardware: such as soft tags, hard tags, and anti-theft alarms.

2. Paste warning slogans in places where goods are easy to be stolen: Stealing in shopping malls is also a crime, please do not defy the law.

3. Install monitoring systems and monitors, and display valuable and stolen goods in a more obvious position.

4. Train salesmen on anti-theft knowledge.

The barcode anti-theft of the supermarket is an electronic label (not all products are brought), the front is a barcode, the reverse side of the self-adhesive is a miniature coil, has been made into one, the barcode electronic label is divided into soft labels and hard labels, the cost of soft labels is low, directly adhered to the more "hard" goods, soft labels can not be reused;

Hard tags have a higher one-time cost than soft tags, but they can be reused, and hard tags must be equipped with a special nail extractor, mostly used for soft and easily penetrating items such as clothing.

Decoding requires a decoder, the decoder is mostly a non-contact device, there is a certain decoding height, when the cashier collects or bags, the electronic tag can be decoded without touching the degaussing area.

There is also a device that synthesizes the decoder and the laser barcode scanner together, so that the collection and decoding of goods can be completed at one time, which is convenient for the work of the cashier.

The detector is generally a detection system device at the entrance and exit of the shopping mall or the cash register channel. After receiving the correct amount due from a customer for a product, the cashier can authorize the product to legally leave a designated area by neutralizing the label affixed to the product.

When undecoded goods are taken out of the mall, an alarm will be triggered when they pass through the detector device (mostly in the shape of a door), so as to remind the cashier, customers and mall security personnel to deal with it in a timely manner.
