Topics and discussions on anti-theft of commodities are carried out everywhere. I think that in addition to merchants should add university law, use legal weapons to protect themselves, and law enforcement agencies to increase law enforcement, it is very important that businesses should be good at applying modern electronic technology and related management methods to protect their own interests.
Commodity Electronic Anti-theft System (EAS) has been introduced in Shenzhen in 1993, and has experienced 7 years of development and application history in China. In the past 7 years, the application of this technology by merchants can be said to have a reputation. Many businesses agree that their anti-theft effect can indeed reduce the loss of goods; at the same time, some businesses believe that: on the one hand, the system equipment investment is too high, and the actual effect is not cost-effective compared to the equipment investment; on the other hand, the product quality and performance are unstable, often There are some situations that are very embarrassing and passive for businesses. From customer complaints, to courts and media exposure. In general, the application of this technology is rapidly gaining popularity, and has become an indispensable facility for certain types of shopping malls. Now, the whole country has applications except Tibet. Before we buy EAS equipment, we should first understand the anti-theft effect of EAS. From the perspective of crime prevention, the main effect of EAS is its deterrent effect, so that people who have the idea or idea of ​​stealing should not try the law by themselves. The deterrent effect should account for about 70% of the actual total effect; the other 30% effect is that EAS can intercept those who try the method.
How should merchants purchase electronic anti-theft systems (EAS)? We believe that it can be considered from the following aspects.
 1 System design
After it became clear that 70% of the anti-theft effect of EAS came from deterrence, the best anti-theft effect and price ratio could be achieved by selecting the correct system design scheme according to the mall layout and format. Generally speaking, convenience stores, specialty stores, specialty stores, including apparel stores, audio-visual stores and other shops with a business area of ​​several hundred square meters, adopt the method of total export detection and protection. Large-scale comprehensive supermarkets, shopping malls, warehousing malls, etc., are suitable for the use of cashier channel detection and protection, similar to the installation of elephant Carrefour stores. Both methods can control the input of anti-theft for the unit business area, including the input of equipment and loss prevention personnel within a certain range, and the deterrent effect of anti-theft can be significantly increased. According to our experience, the investment of EAS anti-theft equipment per square meter of business area is controlled within 100 yuan. The larger the business area, the lower the equipment investment cost.
2 Important indicators to measure the performance of EAS equipment
The physical technologies used by EAS are divided into three most common types: radio frequency technology, acoustomagnetic technology, and electromagnetic technology. But not every physical technology is perfect, they all have their inherent advantages and disadvantages. The system's detection rate and false positive rate of tags are the two most important indicators to measure the performance of the technology and equipment. The detection rate refers to the detection ability of the EAS detection antenna to a certain size label within the design installation width. The field distribution of the detection antenna is not uniform, and the detection rate of the normal system should be above 85%. The concept of false alarm rate has always been relatively ambiguous. The explanation that is usually more suitable for shopping malls is: the number of false alarms caused by the environment or non-anti-theft tag objects in a unit time under normal use conditions of the detection antenna. In daily real life, objects with physical characteristics similar to electronic anti-theft tags can often be found, and when the object passes through the detection antenna, it will inevitably generate false alarms. In terms of the false alarm rate, shopping malls are often the most susceptible to misleading from equipment suppliers. In any technical EAS, the false alarms cannot be zero.
3 Technical advancement
To improve the absolute index of the EAS detector: that is, the detection rate is high, and the false alarm rate is low, at present, only EAS, which truly has intelligent digital technology, can meet the requirements. The technology uses high-speed A / D conversion of analog signals received by the EAS antenna, and computer processing of the digital signals, using artificial intelligence to identify the characteristics of electronic tags. Only EAS with this intelligent digital technology can be used in various electromagnetic environments, which can reduce false alarms while increasing the detection rate of the system. Currently, only a few companies in the world own the technology. What is very gratifying is that at the Beijing International Commercial Facilities Exhibition on March 21-23, 2000, Shenzhen Pronomar took the lead in launching products of this technology in China. This brings good news to our entire retail industry in terms of loss prevention.
  4 Price factors
The price of EAS equipment is a very important factor. Now, more and more self-selected shopping malls have considered EAS as a necessary facility, and they are also very concerned about the investment of EAS equipment and the return of the actual anti-theft effect. Now, Shenzhen Pronomar Company launched the EAS equipment leasing plan for chain business enterprises, which can meet the needs of most chain business enterprise customers for commercial loss prevention facilities. It is also a concrete manifestation of the company's corporate purpose of contributing to the domestic retail industry.
5 System technology compatibility
When we choose EAS equipment, don't forget its compatibility. There are two aspects to note here: First, if we are a commercial chain company, we must pay attention to the EAS equipment with the same physical characteristics for each store. This will bring convenience and benefits to future label purchases, system maintenance, and upgrades. Second, when shopping malls use EAS equipment, one of the most important expenses is long-term purchase of consumable materials. We must remind all merchants to pay attention to the choice of EAS technology compatibility, to avoid the monopoly of the anti-theft label market, and the increased cost of the anti-theft label.
 6 System comprehensive supporting capacity
When choosing an EAS supplier, one must consider its system's comprehensive supporting capabilities. Because the entire EAS system, in addition to the detector, also includes a soft tag decoder, hard tag unlocker, and various types of soft and hard tags. If the performance of the soft tag decoder is not good, the soft tag may not be accurately killed, which may cause an alarm when the customer detects the antenna through the EAS, causing embarrassment and disadvantage to the customer and the merchant. The decoding speed of the soft tag decoder is also a comprehensive consideration. A good soft tag decoder should have the characteristics of scanning frequency bandwidth, high decoding height and fast decoding speed. Soft labels are still mainly imported, and domestic production of some physical technology soft labels is still in progress, and their performance needs to be substantially improved. Shopping malls should pay attention to the phenomenon of sub-charging. The performance indicators of hard tags are often overlooked. When purchasing, pay attention to its tensile strength and Q value, and whether the steel nail is easy to be rotated out (mainly for slotless optical nails). Hard labels with poor quality are more likely to be destroyed. Therefore, when selecting an EAS equipment supplier, its comprehensive system supporting capabilities should be considered.
 7 Product standards and quality systems
The EAS industry is a small but emerging industry. Some manufacturers, especially some domestic manufacturers, often ignore their product standards and quality systems. The products they produce have neither product standards nor quality assurance. Who dares to use such products? When we choose EAS, we can no longer blindly listen to suppliers introduce themselves. We must examine their product standards and quality systems, including the quality system for engineering installation.
8 Experienced and long-term stable quality service system
Merchants who have used EAS know that EAS is an item with relatively high service requirements. The equipment does not work properly, which immediately increases the loss of goods. False alarms on the device range from embarrassment to customers and from serious consequences to merchants such as customer complaints, media exposure and legal proceedings.
As the saying goes: three-point equipment, seven-point management; how to make good use of EAS, formulate a set of correct EAS application processing solutions, and form habits, all of which require businesses to complete under the guidance of experienced EAS equipment suppliers. Under the guidance of a professional and experienced supplier, it is possible to avoid conflicts between many customers and stores in the future. A large, experienced and service provider can bring us a sense of security and trust. The continuous and effective training and service provided by the supplier to the mall loss prevention staff will enable the role and effectiveness of EAS to be maximized, thereby bringing good economic benefits to the merchant. This is exactly the purpose of our purchase of EAS.
