Electronic commodity anti-theft systems (EAS) come in a variety of forms and deployment scales to meet specific business security needs. There are eight factors to consider when choosing an EAS system for your retail environment:

First, the detection rate

The detection rate refers to the average detection rate of non-degaussed tags in all directions in the monitoring area. It is a good performance indicator to measure the reliability of the EAS system. A low detection rate often means a high false alarm rate. For the three most commonly used technologies in EAS systems, the benchmark average detection rate of the most recent acousto-magnetic technology is above 95%, that of RF systems is 60-80%, and that of electromagnetic is 50-70%.

Second, false positive rate

Tags from different EAS systems often cause false alarms. Labels that are not properly demagnetized can also cause false alarms. A high false alarm rate makes it difficult for employees to intervene in security incidents, which creates conflicts between customers and stores. Although false alarms cannot be completely ruled out, the false alarm rate is also a good indicator of system performance.

Third, anti-interference ability

Interference will cause the system to automatically issue an alarm or reduce the detection rate of the device, and the alarm or no alarm has nothing to do with the anti-theft label. This can happen in the event of a power outage or high environmental noise. Radio frequency systems are particularly vulnerable to such environmental interference. Electromagnetic systems are also susceptible to environmental interference, especially magnetic field interference. However, since the acousto-magnetic EAS system is computer-controlled and uses unique resonance technology, it exhibits extremely strong resistance to environmental interference.

Fourth, shielding

Metal shielding can interfere with the detection of security labels. This role includes the use of metal items, such as food wrapped in metal foil, cigarettes, cosmetics, drugs, and metal products such as batteries, CD / DVD, hairdressing supplies, and hardware tools. Even metal shopping carts and shopping baskets can block security systems. Radio frequency systems are particularly susceptible to shielding, and large metal objects can also affect electromagnetic systems. Acousto-magnetic EAS systems are generally only affected by all-metal products, such as cooking utensils, because they use low-frequency magnetoelastic coupling, which is very safe for most other products.

Fifth, strict security and smooth flow of people

A robust EAS system needs to consider store security needs and retail flow requirements. An overly sensitive system affects shopping mood, while a less sensitive system will reduce the profitability of the store.

Sixth, protect different types of goods

Retail goods generally fall into two categories. One category is soft goods, such as clothing, footwear and textile goods, which can be protected by reusable EAS hard tags. The other category is hard goods, such as cosmetics, foods and shampoos, which can be protected by EAS disposable soft labels.

Seventh, EAS soft tags and hard tags-the key is applicability

EAS soft tags and hard tags are an integral part of any EAS system. The performance of the entire security system also depends on the correct and proper use of the tags. It is important to note that some labels are susceptible to damage from moisture and some cannot be bent. In addition, some labels can be easily hidden in a box of merchandise, while others can affect the packaging of the merchandise.

Eighth, EAS nail remover and demagnetizer

The reliability and convenience of the EAS nail remover and degausser is also an important factor in the entire security link. The advanced EAS degausser uses non-contact degaussing to maximize the efficiency of the cash register and speed up the passage speed of the cash register channel.
