Vöruverndarkerfi

Vöruverndarkerfi refers to a system designed to protect goods from theft or damage, particularly in retail environments. These systems are commonly found in stores selling electronics, clothing, and other high-value items. The primary goal is to deter shoplifters and alert staff if an item is being removed from the premises without proper deactivation.

The most common type of vöruverndarkerfi utilizes radio frequency (RF) or acousto-magnetic (AM) technology. Small tags, often referred to as security tags or labels, are attached to merchandise. These tags contain a device that resonates at a specific frequency when energized by an antenna placed at store exits. If the tag is not deactivated or removed by a cashier during a legitimate purchase, it will trigger an alarm.

There are two main types of tags: hard tags and soft labels. Hard tags are reusable plastic or metal devices that are usually attached with a locking pin. Soft labels are adhesive stickers that are typically destroyed or deactivated once removed. Deactivation is usually done at the point of sale using a special device that alters the tag's properties, preventing it from triggering the alarm.

Beyond RF and AM systems, other methods can be employed, such as video surveillance and security guards, though vöruverndarkerfi specifically refers to the tag-based electronic detection systems. The effectiveness of these systems relies on proper implementation, regular maintenance, and attentive staff who respond to alarms promptly.
