What is the EAS commodity anti-theft system

EAS anti-theft system: EAS (Electronic Article Surveillance), also known as electronic goods theft (theft) system, is currently widely used in large retail industry, one of the commodity safety measures.
In the global EAS industry due to different system design and separation of four kinds of system equipment
1, RFID system (all called: radio frequency identification system; low frequency 125K, high frequency 13.46M UHF: 900MH)
2, AM system (all known as: sound and magnetic products anti-theft system frequency: 58KHz)
3, RF system (all called: radio frequency system frequency: 8.2MHz and individual others)
4, EM system (all known as: electromagnetic wave anti-theft system frequency: 1-2MHz) and our company involved in AM (sound and magnetic anti-theft system) RF (radio frequency anti-theft system) EM (electromagnetic anti-theft system) three anti-theft system, we will These three systems on the line to explain in detail.

EAS system consists of three parts: editing
Detector, Deactivator, and Electronic Label and Tag. Electronic tags are divided into soft labels and hard tags, soft label costs are low, directly attached to the "hard" goods, soft labels can not be reused; hard tags one-time cost is higher than the soft label, but can be reused. Hard tags must be equipped with a special nail device, used for clothing class soft, easy to penetrate the items. Decoder is mostly non-contact equipment, there is a certain degree of decoding, when the cashier cashier or bagging, the electronic label without contact with the demagnetization area can be decoded. There are also decoder and laser bar code scanner together with the equipment, so that goods collection and decoding one-time completion to facilitate the work of the cashier, this way and the laser bar code suppliers must be matched with the exclusion of the two Mutual interference, improve the decoding sensitivity. Uncoded goods away from the mall, after the detector device (mostly for the door), will trigger an alarm, to remind the cashier, customers and shopping malls security personnel in a timely manner
EAS anti-theft system main working principle editor
When the customer to buy things to leave the need to pay, the cashier or other special responsible staff will be on the product of the hard (soft) label or additional signs, with the decoder decoder, take down, so that customers can successfully purchase the goods through the door Of the detector, did not take down is pass.
The principle of the workflow:
1. Attach the label to the product
2. In the supermarket, shopping malls, clothing stores and other export channels, install the detector.
3. After the payment of goods through a dedicated decoder solution down, passed.
4. When unpaid goods are exported, the detector detects the label and sends an alarm to intercept the goods.
