EAS stands for Electronic Article Surveillance. It is a cost effective anti-shoplifting system that permits your staff to focus on customers and not have to worry about displayed merchandise walking out the door. EAS systems work by attaching an electronic device, called a "tag" or "label", to the displayed merchandise. If merchandise bearing the electronic device passes by an antenna installed at the store entrance, an alarm sounds alerting your staff that unpaid merchandise is leaving the store.
When a customer brings his or her selection to the cash counter to pay for the item to be purchased, the sales clerk removes the tag from the item or deactivates the label on the item so that the alarm will not sound when the customer leaves the store with the paid for merchandise. EAS technologies are radio frequency (RF), acousto-magnetic (AM) and electromagnetic (EM).
