What is EAS? How does EAS System Work?

According to statistics, the global retail industry loses more than $30 billion annually due to theft. The loss of merchandises and books has seriously damaged the interests of the retailer. So how to prevent shoplifting and protect commercial interest is attracting more and more attention from retailers.

The below information can help you learn more about EAS system. If you understand it and applicate our loss prevention solutions , things will move in a better direction.

What is EAS?

EAS (Electronic Article Surveillance) is a technical method for preventting shoplifting. The first EAS system based on RF technology was invented by Arthur Minasy in 1966. Today, EAS is still the most popular and effective retail security system.

How does EAS Work?

EAS security system usually consists of three components:

Antennas are usually installed at the exits and entrances of stores. There is a detection area between the antennas. They can detect any passing active tags and emit alarms.

Security tags are attached to every commodity that needs protection. The staffs should correctly remove hard tags or deactivate soft labels at the checkout.

Detacher is a tool for staff to remove those reusable hard tags. Deactivator is used to deactivate soft labels. The type of the detacher depends on the type of tag.

Types of EAS System

RF system (frequency: 8.2MHz)

The RF transmitter continuously emits a signal with a frequency of 7.5~8.5 MHz. When an active tag is close to the transmitter, a resonant signal is generated here. The tag reflects this signal to the receiver. The receiver will issue an alarm after processing this signal.

About 50% of retailers in the global retail sector choose RF systems because of its good performance and affordable price.

AM system (frequency: 58KHz)

AM transmitter emits electromagnetic waves at a frequency of 58 kHz. When a tag with a frequency of 58KHz enters the antenna detection area, cross resonance occurs. Then the tag will gain energy from the antenna. And the energy accumulated will be reflected receiver after four consecutive times. After AM receiver processes, it will generate a current signal and then issue an alarm.

The AM system has more stable performance and more aesthetics. As a result, about 35% of retailers around the world choose AM systems.

EM system (frequency: 1~2MHz)

The EM transmitter and receiver form a closed loop magnetic field. When the EM tag enters the detection area, it will magnetize and generate a weak current signal. After EM receiver processes the signal, it will generate a DC drive horn alarm.

The EM tag has the right size and low price. So EM system is still very popular in the library, bookstore, etc.

Four Advantages of Installing EAS

  1. Firstly, it can reduce theft.
  2. Secondly, the EAS security system itself is also a deterrent to thieves.
  3. In addition, it can reduce employees and can reduce many unnecessary expenses.
  4. Not only that, it can improve the store environment and give customers a better shopping experience.
