The composition of EAS system and How to Loss Prevention


How EAS system working


As you can see in the drawing at the top, the EAS system works like this: A tag or a label attached to a product responds to a specific frequency emitted by a transmitter antenna (usually one pedestal of the entry/exit gate). The response from the label or tag is then picked up by an adjacent receiver antenna (the other pedestal). This processes the tag response signal and will trigger an alarm when it matches specific criteria. The distance between the two gates, or pedestals, can be up to 80 inches wide. 

Usually, the principle of the EAS anti-theft system is testing the effective security tags or security labels in the antenna area, as long as there is a valid tag is detected, the antenna will alarm. So when the thief stole the goods which protected, the antenna will alarm. But the paid goods will not clarm because the cashier have a equipment which can decode the soft label or take down the hard tag, so the detection area will not appear the effective tags and labels, so the gates let it pass without an alarm.

Knowing the principles of the surveillance system, you can easily understand the EAS system.

Antenna: Antenna is essential, installed near the door, and continuously detecting the un-cancelled labels in the area. It alarms if it detects one. The paid items with decoded soft label or without hard tags will not start the alarm, so that alarming means there is unpaid goods will be taken out.

Hard tags: Hard tags are the most commonly used and most affordable tag solution. They have high sensitivity and can be reused, which ensures excellent protection performance and are low-cost, but highly cost-effective. Hard tags usually need to be attached to the goods using a pin and lanyard, or similar.

Tag detacher: After payment, the cashier will use a detacher to separate the tags and pin, so that those hard tags remain in the shop and can be used again. In this way, the paid goods will not start the alarm because there is no tag when they pass the door.

Soft label: Soft labels are mainly used for goods which can’t be protected by hard tags, such as electronics, boxes, etc. There is adhesive on the back of soft tags. You just need to paste the tag on the protected products, but be careful, it can’t go on top of any warning or other important information on the product. However, because it has a very strong adhesive, any attempt to forcibly remove it may cause surface damage to the goods making illegal activity obvious.

Label Deactivator: After payment, the Label Deactivator will decode soft labels so that they no longer set off the alarm, and the buyer can safely pass the anti-shoplifting antenna. The deactivation unit is placed next to the point-of-sale equipment for quick and easy checkout.

Generally the EAS system is composed of these elements. Special merchandise or more targeted items/projects may be different. If you need more information please contact us, we will be pleased to answer any questions.
