One of the common security barriers to reducing shoplifting and improving store security is a security tag or label.
These tags, along with magnetic detachers, form animportant part of an Electronic Article Surveillance (EAS) system.
With neodymium magnets integrated into their locking mechanism, security tags ensure improved protection and deterrents against theft.
In this brief guide, we will explore how neodymium ring magnets are utilized in security tags, their locking mechanisms, and the impact they have on reducing theft.
But first of all, let’s understand the function of security tags.
What is the Function of Security Tags?
Security tags serve as small “signal transmitters” that are attached to items in retail stores, signaling the presence of a protected item when it passes through a specific range of EAS antennas. The primary purpose of security tags is to discourage shoplifters and initiate an alarm if an unauthorized removal is attempted.
What are the Types of Locking Mechanisms in Security Tags?
Security tags commonly employ two types of locking mechanisms: mechanical locks and magnetic locks. Mechanical locks typically involve a physical mechanism that requires a specific tool or force to open, while magnetic locks utilize the power of magnets to secure the tag.
The Role of Neodymium Ring Magnets in Security Tags:
Neodymium ring magnets, known for their exceptional strength, play a vital role in the effectiveness of security tags.
The choice of magnetic strength depends on the desired level of security and the difficulty of removing the tag without a detacher.
The neodymium ring magnet is typically embedded within the security tag, forming the magnetic lock mechanism. The strong magnetic force holds the tag firmly in place, making it challenging to remove without the corresponding detacher.
Neodymium magnets are ideal for this purpose due to their high magnetic field strength and small size, ensuring a secure attachment that is difficult to tamper with or circumvent.
How Neodymium Magnets are used for Security Tags?
The white tags are equipped with two metal strips and a tiny, weak magnet. They use magnetostriction, which is the property of ferromagnetic materials to change shape when exposed to a magnetic field.
Stores have sensors near doorways that emit and receive a weak magnetic field. When an active anti-theft tag (not demagnetized) enters this zone, it oscillates and the sensor detects the magnetic wave changes, setting off an alarm.
During the checkout process, cashiers use a device equipped with a neodymium magnet to demagnetize the anti-theft tag. Demagnetizing the tag prevents oscillation from occurring, thus silencing the alarm. Conversely, the tag can also be reactivated by magnetizing it with a neodymium magnet, allowing it to be used again for future protection.
What are the Benefits of Neodymium Ring Magnets in Security Tags?
The use of neodymium ring magnets in security tags offers several advantages. Firstly, their strong magnetic force provides a reliable and robust locking mechanism that deters theft attempts. The difficulty of removing the tag without a detacher adds a layer of security for retailers.
Furthermore, neodymium ring magnets are compact, allowing for easy integration into security tag designs without adding excessive weight or bulk. This ensures that the tags remain inconspicuous and do not interfere with the shopping experience.
The Future of Neodymium Ring Magnets in Security Tags
As technology continues to advance, neodymium ring magnets are likely to play an even more significant role in enhancing store security. With ongoing research and development, it is anticipated that neodymium magnets will become even stronger and more efficient, providing an increased level of protection against theft.
The Bottom Line:
Neodymium ring magnets have revolutionized the effectiveness of security tags in reducing shoplifting incidents.
Their powerful magnetic force, compact size, and secure locking mechanism make them an ideal choice for deterring theft and improving store security.
By incorporating these magnets into security tag designs, retailers can enjoy the benefits of enhanced protection, reduced losses, and increased customer confidence.
