How Do EAS Labels Work?

Electronic article surveillance, or EAS, is a type of technology that prevents shoplifting. EAS is most often used in anti-theft systems in retail stores but can also be found in libraries and office buildings. EAS usually involves three components:

  • At least one electronic antenna
  • A deactivator or detacher
  • An electronic tag

The antenna is typically found in EAS system pedestals installed at a store’s entrances. Though tags used to only be available in clunky form factors with limited applications, today you can use EAS labels that come in a range of shapes and sizes. Suited to high-volume, low-value merchandise like books, CDs, hardware, non-perishable groceries, cosmetics and pharmaceuticals, EAS labels are available in both acousto-magnetic (AM) and radio-frequency (RF) systems.

How EAS Labels Work

EAS labels work the same way EAS tags do: they stay in constant communication with a store’s EAS system and trigger an alarm to sound if they pass the EAS pedestals without being properly deactivated. Unlike EAS tags, EAS labels are essentially flat stickers and can be easily and quickly adhered to products.

The adhesive side of an EAS label has a printed circuit that contains all the technology needed to make it work with an EAS system. The only requirements are that the printed circuit must remain undamaged, and the EAS label must be placed on a flat surface and not folded or bent.

It is recommended that you avoid sticking the EAS label on or near metallic items, as to not disturb the printed circuit. Just like EAS tags, you only need one EAS label per item.
