How does the insertable AM ​​security label work?

The insertable AM security label is a technology commonly used in retail and commodity theft prevention. This label uses specific physical principles to protect commodities from theft. The following is the working principle and related characteristics of the insertable AM security label:

1. Basic Principle

AM security labels are based on acoustomagnetic technology and are usually composed of the following main components:

Oscillator: There is an oscillator inside the label that oscillates at a specific frequency (usually around 58 kHz) to generate an acoustomagnetic signal.

Magnetic material: The label contains magnetic material, usually a specific alloy that can respond to external magnetic fields.

Antenna: There is an antenna in the label for transmitting and receiving signals.

2. Working process

The working process of the insertable AM security label can be divided into the following steps:

Signal emission: When the label is placed in the monitoring area (such as the entrance and exit of a supermarket), the monitoring system will continuously emit acoustomagnetic signals of a specific frequency.

Signal response: If the label is in the monitoring area, the oscillator in the label will receive the signal and start to oscillate. At this time, the magnetic material in the label will resonate and reflect back a signal of a specific frequency.

Detection signal: The receiver of the monitoring system will monitor the signal reflected by the tag and compare it with the preset signal. If a valid signal is detected, the system will determine that the product has an unremoved security tag.

Alarm system: When the monitoring system detects an unremoved tag signal, it will trigger the alarm system, and the alarm will sound to remind the staff to deal with it.

3. Features and advantages

Concealment: Insertable AM labels are usually designed to be small and concealed, not easy to be found, and can effectively prevent theft.

High reliability: AM technology has strong anti-interference ability and is not easily affected by other electromagnetic signals.

Reusability: AM security tags are generally reusable, and merchants can remove the tags through a dedicated decoder after each sale, which is convenient for management.

Various shapes: Insertable AM tags have a variety of shapes and sizes, which can be selected according to the needs of different products.

4. Application scenarios

Insertable AM security label are widely used in the retail industry, especially for the anti-theft protection of high-value goods such as clothing, cosmetics, and electronic products. In addition, AM tags can also be used in the fields of book theft prevention in libraries and exhibit protection in museums.

5. Removal and management

In order to effectively manage AM security tags, merchants usually equip them with special removers. When customers purchase goods, cashiers use removers to remove the security function of the tag to ensure that the goods can be taken out of the store smoothly.

Insertable AM security label are an effective anti-theft solution that monitors unremoved tags through acoustic and magnetic technology, providing efficient security protection.
