EAS-Electronic Article Surveillance
- EAS has evolved over the years and has its roots in the EM (Electro-magnetic) range of products, the system generally comprised of Posts (units located at the door that trigger and alarm is something is taken) a deactivator or re-activator and labels.
- The first sites were Libraries, the thin label had advantages, was flat, very discreet, but the downside is it didn’t work on metal/liquid, and the posts were 750mm apart, not an ideal width for a retailer.
