EAS signal transmission mode is mostly analog, but in the global digital wave, both acoustomagnetism and radio frequency inevitably follow the footsteps of digitalization, and a series of products of DSP (Digital Signal Processor) have been developed. Simulation technology is easily disturbed by various electromagnetic fields, especially when the distance between detection gates is long, which will lead to more false positives and false negatives. The accuracy of digital products in signal acquisition and processing is improved, which avoids the interference of many environmental and human factors on EAS equipment and greatly improves the detection width of EAS. And DSP collects and processes all kinds of signals in real time through software. Due to some inevitable problems in software design, various DSP products on the market are not perfect. Therefore, although DSP is the development direction of EAS in the future, users should not be blindly superstitious. With the passage of time, DSP technology will become more and more perfect, and the type, quantity and inventory of products sold can be directly known through EAS decoding process, which is the direction of EAS technical efforts.

At present, the anti-theft function of electronic articles is relatively simple, mainly due to the consideration of commodity anti-theft, and its installation is also set and wired as a single system. However, the next development of EAS will definitely jump out of the existing single commodity management mode, organically integrate with CCTV monitoring and anti-theft alarm system, and realize the integration of commodity anti-theft, access control attendance, logistics management, monitoring and other functions.

With the popularity of electronic goods monitoring and the maturity of commodity prevention concepts of many chain retailers, commodity labels will be more and more favored by many businesses. The so-called commodity identification means that manufacturers put electronic labels in commodities or in the packaging of commodities during the production process. For retailers, the labeling of goods saves the trouble of manual labeling, and the electronic label is hidden in the interlayer of cardboard or in the product label (this hidden electronic label is also called the source label), which is not easy to be found and destroyed, which can better prevent the occurrence of internal thieves and external thieves, and at the same time, open-shelf sales increase the unit sales area and profit. For manufacturers and packers, adding a label to the production line will not have any impact on product performance; The open-shelf sales of goods have greatly increased the supply; At the same time, it can prevent external electronic labels from covering the original description text of the product, and maintain the integrity of the graphics and commodity information of the original packaging. Although the source label increases the cost of manufacturers, it also increases the market competitive advantage of products because of the characteristics of anti-theft labels.

The security industry has always advocated the organic combination of technical defense and civil air defense, and EAS, which is mainly used in the commercial field, is no exception. EAS can't overcome the problems of false positives and false negatives. The retail industry is facing customers who come to shop, so it is particularly important and sensitive to deal with the alarm when the equipment appears. As an EAS supplier, when providing training for users, it is necessary to explain various possible accidents to users, so that businesses can be confident in handling alarms. As a retailer, we should further improve the quality training of employees, deal with all kinds of alarm situations as humanely as possible, and reduce the emotional harm of false alarm to customers; As a customer, we need to understand the limitations of technology, cooperate with merchants to check and reduce unnecessary disputes and troubles.
