If it is an ordinary apple, not ridge magnetic strip, the security gate will not alarm.
Question 2: How does the supermarket barcode do anti-theft? Ordinary paper barcodes are not magnetic and do not have anti-theft features.
Now the large supermarkets, most of the goods in the production of a paste the anti-theft labeling process.
Supermarket anti-theft tags have a variety of acoustic magnetic, radio frequency, hard tags, soft tags, through the composite processing of some of the labels with barcodes at the same time can also have anti-theft function. Zhuhai Hanbo anti-theft labels to remind you, please do not deliberately destroy the supermarket anti-theft accessories.
Problem three: how to supermarket anti-theft? Supermarket anti-theft there are three main means, 1, supermarket monitoring 2, supermarket loss prevention 3, supermarket anti-theft access control equipment
Supermarket monitoring: supermarkets and shopping malls will now be installed to monitor the closed-circuit electrical appliances, installed in the supermarket entrances and exits, the main channel, the corner
and so on. Supermarkets are generally specialized with the loss prevention office, there are people responsible for watching the monitor screen at all times to see the supermarket
dynamic.
Supermarket loss prevention: Supermarket loss prevention has a specialized loss prevention department, but also the security department, the purpose is to prevent the loss of supermarkets
loss. General supermarket entrances and exits, cash registers, gates, security channels, staff channels have loss prevention security personnel. Supermarkets
also equipped with plainclothes loss prevention, specializing in supermarkets within the brake customers to catch the thief.
Supermarket anti-theft door with supporting equipment: Supermarket anti-theft door with magnetic anti-theft labels, affixed to the goods, if not
demagnetized by the cash register, will trigger the security door alarm.
Yiante supermarket anti-theft
Question 4: How do you get the anti-theft system in the supermarket First of all, the current market mainstream supermarket anti-theft system is only three kinds of radio frequency system, acoustic magnetic anti-theft system, electromagnetic wave system.
Principle of operation:
○ radio frequency system
Radio system (Radio Frequency, RF) using radio waves as a transmitter-receiver signals, detection of the frequency range of 7.x ~ 8.x megahertz. Transmitted signals are radio signals, with cell phones, radio is the same signal, just a different frequency. The biggest advantage of the radio system is that the system cost is very low, easy to install. But because of its anti-theft tags for the ring coil type, so the system is susceptible to some items of interference, such as cash registers and other electronic products, metal objects, etc., resulting in false alarms or non-reporting of the system.
The radio system has soft and hard two kinds of labels, can protect most of the items in the mall. The distance between the two supports is generally not greater than 0 9 meters, usually used in only one import and export of the mall. Radio system has a vertical and channel type two, used to protect department stores, clothing stores, supermarkets and so on.
○ acousto-magnetic system
The tuning fork only in the case of the same frequency of oscillation caused by *** vibration. Acousto Magnetic system (Acusto Magnetic) is the application of this physical principle, to achieve almost zero false alarm operation, fixed in the goods on the Acousto Magnetic system tags into the system's detection area, will produce *** vibration, but only in the receiver to receive four consecutive *** vibration signals (every 1/50 seconds once), before issuing an alarm.
Acousto-magnetic system is characterized by high anti-theft detection rate, almost zero false alarms, good anti-jamming, protection of the exit width of up to 3.5 meters, there are two kinds of soft and hard anti-theft tags, most types of goods in the mall can be protected, but also repeat the demagnetization, even next to the POS cash registers, the system is still able to work properly.
Acoustic magnetic systems include vertical systems, channel systems and hidden systems of different types, there are more than 10 types of models to choose from, can be widely used in department stores, supermarkets, specialty stores, video stores, grocery stores, drugstores, but also can be used in office buildings and other environments.
○Electromagnetic System
Electromagnetic System (Electromagnetic System) uses electromagnetic waves as the detection signal.
Electromagnetic system of the label is the smallest, the label price is cheap, can be repeated demagnetization, but easily affected by magnetic or metallic substances and produce false alarms. Protection of the exit width is generally around 0 9 meters. The system will not have an impact on magnetic items attack such as audio tapes, video tapes, magnetic cards).
The new generation of channel electromagnetic wave system is a software-controlled electronic anti-theft system, the use of digital processing technology and demagnetization system, cash register monitoring, closed-circuit television monitoring system into one. The use of rapid demagnetization board, can be repeated demagnetization, the system cost is high. Electromagnetic wave system has two kinds of vertical and channel type. Application environment in libraries, bookstores, audio stores, hotels, supermarkets and so on.

Question 5: How to prevent theft in large supermarkets is commonly used EAS anti-theft program,
in foreign countries have a more mature history of application,
According to the experience of Hangzhou Meister Intelligent Technology,
is usually Using RF or acoustic magnetic series of products,
including hard and soft tags, self-tagging tags, decoders, nailers, anti-theft antennas, etc.
Supermarket merchandise with tags, if the cash register does not decode or remove the tag,
take the door antenna near the antenna will be sensed by the alarm.
Question 6: What is the best way to prevent theft in the supermarket? The concept of barcode
Barcode or barcode (barcode) is the width of a number of black bars and blanks, in accordance with certain coding rules, to express a set of information graphic identifiers. A common barcode is a pattern of parallel lines made up of black bars (referred to as bars) and white bars (referred to as blanks) of widely varying reflectivity. Bar code can be marked out items of the country of production, manufacturer, commodity name, date of production, book classification number, mail starting and ending locations, categories, dates and many other information, and therefore in the circulation of goods, library management, postal management, banking system and many other areas have been widely used. Detailed supermarket merchandise anti-theft solutions
First, the demand for analysis
With the growing popularity of apparel chain stores and self-service supermarkets in the country, the phenomenon of lost merchandise is also becoming increasingly serious, how to prevent theft of merchandise, to protect the security of the shopping mall has been the concern of an increasing number of retailers. Shopping mall electronic anti-theft system (EAS) a change in the traditional way, such as people to people, technology-based defense, because of its ability to effectively prevent the loss of goods, improve economic efficiency, has gradually been recognized and accepted by the majority of businessmen, and the application of the Chinese market is becoming more and more widespread.
Most of the world's large retailers use electronic anti-theft devices. In Beijing, Shanghai, Guangzhou, Shenzhen and other commercially developed shopping malls in major cities are installed EAS system. EAS has become the mainstream of the supermarket anti-theft and trend!
Second, the shopping mall electronic anti-theft system classification and performance indicators comparison:
There are four main technologies in the EAS system, respectively, radio frequency, electromagnetic, acoustic magnetic, radio frequency identification. Due to the electromagnetic and radio frequency products are inexpensive, and their labels are usually permanently affixed to the goods or commodity packaging; and microwave and acoustic-magnetic labels to be more expensive, most of the general supermarkets will choose electromagnetic and radio frequency. So to electromagnetic and radio frequency description.
Radio frequency
Mainly by the detector, decoder and electronic tags composed of three parts, auxiliary equipment and lock opener.
Electronic tags are divided into soft tags and hard tags, soft tags lower cost, directly adhered to the harder goods, soft tags can not be reused; hard tags a one-time cost of soft tags higher, but can be reused. Hard labels must be equipped with a special nail picker, mostly used for clothing soft, easy to penetrate the goods. Decoder is mostly non-contact equipment, there is a certain decoding height, when the cashier cashier or bagging, electronic tags do not have to contact the demagnetization area can be decoded. There will also be decoder and laser barcode scanner synthesized into a device, to achieve the goods collection and decoding a one-time completion of the work of the cashier to facilitate the work of this way must be and laser barcode supplier to match, to exclude the mutual interference between the two, improve the sensitivity of the decoding. Detectors are generally for the mall entrances and exits or cashier channel at the detection system devices. After receiving the correct amount of money payable by a customer for the purchase of a product, the cashier can neutralize the label affixed to the product and authorize the product and legally leave a designated area. Undecoded merchandise taken out of the mall will trigger an alarm when it passes through the detector device (mostly door), thus alerting cashiers, customers and mall security to deal with it in a timely manner.
Electromagnetic system
Mainly consists of anti-theft antenna, demagnetizer, magnetic stripe; auxiliary and magnetic stripe detector components.
Comparison of performance indicators:
1. Detection rate:
Detection rate refers to the unit number of valid tags in different directions through the detection of different locations in the region of the number of alarms.
Wireless radio frequency: for daily necessities, radio frequency system due to its soft tag for the ring coil type, if the protection of goods on the tin foil or metal components, the loss of the alarm effect, the comprehensive report
low alarm rate. Generally 60-80%;
Electromagnetic system: As the consumables used for the magnetic stripe, by the foil or small metal components do not have much impact, the alarm rate can be large 95% between.
2, the ability to resist metal interference:
The most serious impact of metal shielding is the radio/radio frequency RF system, which may be radio/radio frequency in the actual use of one of the main limitations of the performance. Electromagnetic wave system will also
affected by metal objects, when large pieces of metal into the electromagnetic wave system detection area, the system will appear downtime phenomenon, when the metal shopping carts, shopping baskets pass by, the goods inside
even if there is a valid label, but also because of the shielding and does not produce alarm.
3, the width of protection:
Malls need to consider the protection of the anti-theft system width, so as not to narrow the width between the supports, affecting the customers in and out. Moreover, shopping malls hope that the entrances and exits are spacious.
Electromagnetic systems are generally installed width of 75-120 cm, RF 90-160 cm
4, the protection of the type of goods: ...... >>
Question 7: How does the anti-theft alarm at the entrance of the supermarket work? To know that all the goods in the supermarket can not be 100% of all the goods to do processing. Can do 5% is considered good. Even if you do deal with, the goods may also be stolen, so the first thing to do is to set up a loss prevention concept for supermarket management, loss prevention work is actually psychological tactics, and will not be discussed here. As for the anti-theft principle of the anti-theft device will not make further explanation, because the supermarket will have to test it to prevent theft, said too white, the supermarket's alarm is equal to the white installed. But we can put a lot of use out, such as soft tags, supermarkets can let suppliers of goods in the packaging on the wear it built-in, customers to the cash register to pay at the same time, the cash register is equipped with a decoder (demagnetizer) built into the soft tags inside the lift off. If there is no cash register to deal with the goods, when passing through the security door will be issued when the alarm prompts.
Question 8: how to take down the supermarket anti-theft magnetic buckle? Anti-theft buckle to open the method,
Method 1: find a magnet and magnetic buckle lock contact (magnetic buckle raised) slightly shaking the magnetic buckle so that the steel beads can be fully in contact with the magnet to pull out the steel pin, pay attention to the magnet and the lock contact do not pull out the steel pin, because if the steel beads if there is no magnet attraction will only pull the more tight. Try to pull out the steel pin after full rotation.
Method 2: the previous steps and the same as above, the magnet and the lock contact with the magnet buckle hand slightly with a little force to the magnet tapped and then rotate the magnetic buckle, and then use your fingernails to pull out the steel needle. Because of the supermarket magnetic buckle for a long time recycling use, some of the steel beads have not so smooth each other, or on the rust. The sensitivity has decreased.
Method 3: Violent demolition, violent demolition is actually very simple just need to burn the location of the lock cylinder, is raised that piece of tool to open a small gap out of the spring, and then the steel needle up on the table to knock a few times, gently pull out the steel needle on the ok. If it is not convenient to use fire to burn the location of the lock cylinder in the removal of the buckle with pliers clamp buckle edge is easy to open the buckle, because the edge has a small piece of hollow.
Question 9: How to unlock the supermarket anti-theft buckle? Anti-theft buckle inside a magnetic coil, LC oscillator principle. When the anti-theft buckle into the immobilizer protection zone, the immobilizer senses the magnetism, it began to alarm. Experts explain the principle of unlocking the anti-theft buckle (attached) locking principle: the nail on the rod has two pairs of small grooves (attached) (schematic drawing only one of the pairs of grooves), when the nail from the bottom of the anti-theft buckle inserted, the buckle in a few small steel balls will slide to the nail on the groove of the location of the grooves; and the steel balls on top of the ring at the top of the spring under the pressure of the iron ring to firmly stuck in the groove they are in. So that the nail from the bottom again ***, ordinary brute force is impossible to do. How to unlock the Linzhang Haojiaoduo supermarket anti-theft buckle unlocking principle: the use of professional locksmith (also known as the nail, composed of magnetic ring and magnetic core, the combination of the two to form a vortex magnetic force, the magnetic force is concentrated in the center of the locksmith, pulling force up to 8500GS, through the strong locksmith so that the small UFO anti-theft buckle can be easily opened), you take the invoice to the shopping mall where you purchased the goods at the time, to find the help desk to help take it down! It's done. Shopping malls are equipped with a powerful lock opener. Then introduce the tips of the netizens themselves should be able to have a strong magnet, if not, you can wrestle with the anti-theft buckle, this method may damage the anti-theft buckle, thicker strong clothes will not be damaged (thinner is also fine), my is a thin sweater, success. There are still wire coils inside the anti-theft buckle. My solution: because there is no strong magnet, and do not want to fall hard, so use a blade to pry open a slit, and pry open with a word change cone. Perfectly removed.
Question 10: How to prevent theft of supermarket goods? The current use of anti-theft tags. In the cash register is through demagnetization to kill the anti-theft tags so that it does not alarm
