Introduction

Have you ever wondered how security tags work when you’re shopping? The small but powerful devices deter shoplifting in shops. If someone tries to take something without paying, the tag sends a signal that alarms a security system. So, how is it done? In this article, we’re going to explain security tags in easy language so that anyone, from children to experts, can understand them.

What Are Anti-Theft Tags

Anti-theft tags, or security tags, are small devices that are put on merchandise in a store. Security systems use them to check if a person is shoplifting. If a person attempts to exit a store without taking off or deactivating the tag, it triggers a warning signal.

Types of Anti-Theft Tags

Stores use different security tags based on their product offerings. The most common of these are:

• Magnetic Security Tags – Opened using a special magnet at checkout time.
• Radio Frequency (RF) Tags – The signals that security gates receive.
• Acoustic-Magnetic (AM) Tags – Stronger and used on more objects.
• Ink Tags – If removed roughly, they spill ink on the product.

How Do Magnetic Security Tags Work

Magnetic security tags are used in a large number of clothing stores. There is a lock that is opened using a special magnet only. Here is their working process:

• Tag is applied: The store’s employee places the tag on the product.
• Security Checkpoint: The store has security gates that can detect active tags.
• Alarm Activation: The gates also activate an alarm when a tag is not removed.
• Removal at Checkout: The cashier strips off the tag using a magnet after purchase.

How Do RF and AM Security Tags Work?

Both RF (Radio Frequency) tags and AM (Acousto-Magnetic) tags work based on signals that security systems can detect.

Radio Frequency (RF) Tags

• Work by sending signals between security gates and tags
• Operate at 8.2 MHz, making them great for small products.
• Used in grocery stores, clothing shops, and bookstores.

Acousto-Magnetic (AM) Tags

• Use 58 kHz frequency, more difficult to block.
• Work well on packaged goods, apparel, and electronics.
• Have a higher detection range than RF tags.

How Do Security Alarms Work With Anti-Theft Tags

Stores use Electronic Article Surveillance (EAS) systems that involve security antennas that are mounted at exits. The security antennas receive active tag signals. An active tag that has not been deactivated will trigger an alarm.

How Security Alarms Work:

• Customer walks toward the exit with an active tag.
• The security system detects the tag’s signal.
• If the tag is active, a ring is sounded.
• Store security continues to check the product.

Deactivating RF and AM Tags

• Cashiers use a deactivation pad to disable the tag’s signal.
• The item is swiped over the pad to hide detection.
• Removing Magnetic Security Tags
• These need a strong magnet to dislodge the pin.
• Only store employees have such tools.

Why Are Retailers in Need of Anti-Theft Tags

Using security tags helps stores in many ways:

• Prevents Theft: Deters shoplifters from stealing
• Saves Money: Avoids losses of stolen goods.
• Keeps Stores Secure: Helps monitor valuable products.
• Improves Customer Experience: Honest shoppers shop without worry.

Conclusion

Now you know how anti-theft tags work and why retailers apply them to their merchandise in their stores. The security tags using RF, AM, and magnetic technologies deter shoplifting and protect their stores.
