What Is an EAS Security System? Why You Should Use it for Your Business

What Is an EAS Security System

There is a lot of technology available today that you can use to improve the security of your business and retail space. One such technology is the Electronic Article Surveillance (EAS) system. The EAS technology has been adopted mostly in retail spaces to help combat theft, inventory shrinkage, and shoplifting. This means it can provide your business with a reliable way of protecting your investment.

The EAS security system uses radio frequency technology, including both RF and AM systems, to detect the articles placed on the product labels, tags, or stickers as they are passed through gates or sensors. As such, the store owner can know if an unauthorized product is leaving the store and take the appropriate measures.

There is so much to learn about this type of system. Keep reading to get a better understanding of the EAS security system.

Components of EAS Security Systems

Components of EAS Security Systems

The EAS security system will only work because there are proper components in place that ensure the best performance. These components include EAS tags, antennas, activation and deactivation systems, and alarm systems.

EAS tags

The EAS tags are what you attach to the merchandise. They do come in many forms, depending on the application. We have the RFID, RF, and AM tags.

The RFID tags use radio waves to identify the tag, while the AM tags will use magnetostriction for the same job. Each tag type has different characteristics, which can determine where best to use them.

The placement of the EAS tags is quite important. They have to be discreet but still work amazingly as they are supposed to. This ensures they do not interfere with the customer experience of the user.

EAS antennas

The antennas are what make it possible for the tags to communicate with the security system. You can come across multiple types of antennas in the market. They include pedestal-style, concealed, and door-frame antennas. Each type of antenna works well for a specific application. Some businesses like to maintain a certain aesthetic, so they would keep the antennas concealed.

The antennas emit signals which interact with the EAS tags. If the item is passed through the detection zone, the antenna picks the signal, resulting in an alarm. Do not worry; the detection is mostly instant and accurate.

EAS Deactivation and Activation

The deactivation process is necessary at the point of sale so that the alarms are not triggered later when the customer passes through the antennas at the door. Cashiers will have specialized devices for deactivating the tags, allowing the customers to exit the retail store without any problems.

Some EAS tags can be reactivated where necessary. This feature means that the merchandise is always protected even after you purchase it. This can be vital, especially for returns or exchanged products.

EAS Alarming Systems

You will definitely need audible and visual alarms to make it easier to detect theft. Without an audible alarm, you would not know what the issue is. Expect sirens or beeps as the alarms, as they can attract attention. Such attention is what most people would want to avoid, thus being a good theft deterrent.

It is still possible to integrate with the existing CCTV and security systems in the retail space. This allows for additional monitoring, recording, and additional analysis if necessary.


How Does the EAS System Work

How Does the EAS System Work

As explained before, you will encounter two types of EAS security systems. They include RF or radio frequency detection and AM or Acousto-Magnetic (AM) detection.

During the detection phase, the RF systems will use the radio waves to communicate with the tags and antennas. As for the AM systems, they use magnetostriction for the same.

RF technology is mostly known for being more versatile and can be used with different existing technologies. Expect it to be effective at detecting the different tags. As for the AM technology, they are quite robust and would work well in places where RF interference might be prevalent.

False alarm reduction

As much as we aim to deter theft, the worst can be false detection. When someone goes through the EAS antennas at the door, they scan the tags to ensure they are properly deactivated. The companies setting up such systems ensure advanced filtering and signal analysis, reducing the chances of false alarm detection. As such, the shopping experience will remain better for the customers.


Applications of the EAS Security System

Applications of the EAS Security System

The EAS security system is loved mostly for its theft detection capabilities. That is why you are likely to find it in many stores for securing merchandise. Some notable places you would get such a system would be libraries, warehouses, convenience stores, and distribution centers.

Retail Spaces

The EAS security system is a big deal in the retail space. The most common application is to prevent shoplifting. This is a better way of ensuring there is no inventory shrinkage. Also, you can find that when people see signs of being monitored by technology, they do not try to steal. Such a warning makes it easier to run a store without worrying that someone might be looking to steal from you.

If you have an EAS security system installed correctly, it can improve the customer experience. This means they are assured of security while making it easy to detag the items at the purchase counter. There will be no unnecessary disruptions generally.

Libraries and Bookstores

It is always important that libraries safeguard books and media items, which can be easy targets for theft. One way would be tagging them with the EAS tags. This discourages theft and makes getting misplaced items in the same library or bookstore easy.

The system may also help with self-checkout systems. This means that you can always work independently at the checkout stage and not have to worry about giving the best customer service to the customers. The EAS system will provide the right balance between security and convenience.

Warehouses and Distribution Centers

As expected, we could not miss having the EAS system as part of the warehouses and distribution centers. They would mostly help with inventory control and management. This is done by deterring internal theft and further minimizing losses during the shipping or receiving processes. You can also get real-time tracking or monitoring of the merchandise as it moves from one section to another.

Another reason is that you also get to experience better supply chain security. The user can safeguard the goods throughout the logistics process. With this additional tracking, you can easily mitigate the risks associated with theft and enhance overall integrity.


Pros and Cons of EAS Security System

Pros and Cons of EAS Security System

The EAS security systems will give you a number of pros, which have made it possible for people to adopt them to various applications in the market. If you can use them correctly, the system will leave you with an effective system. Below are the pros you can expect with the system.


  1. The systems are cost-effective for many businesses. This is because you get a cheaper way of enhancing your security without spending so much on the system. Also, you can ensure there is no inventory shrinkage since the system can alert you in case of theft.

  3. You would also find it a bit easy to integrate with other existing security measures. We are talking about CCTVs, alarm systems, and access control units. This helps ensure you always have the best performance.


  1. Sometimes, you may encounter false alarms depending on how the system is set up. That is why you need to achieve a proper balance between sensitivity to theft detection and minimizing false alarms.
  2. Also, there can be some maintenance and upkeep costs associated with EAS systems. This is vital to ensure that the EAS system has long-term functionality and will always work well.
