Designing a Full Duplex Transceiver to Improve the Detection of Low Cost Resonators Used in Electronic Article Surveillance

Electronic Article Surveillance systems, which are used to help retailers detect shoplifted items, suffer from two major problems. First, the systems often fail to detect EAS tags/labels that are present within the ‘detection zone’ of the gate. Secondly, false detection indications when EAS tags/label are not present within the ‘detection zone’ of the gate. As a result of the unreliability, many of these systems are powered off by the retailer and only provide a visual deterrent to shoplifters. From some samples that INEO has conducted at a number of shopping centers, we estimate that as many as half of these systems are not powered on. The goal of this project is to improve EAS
detection technology to encourage more widespread use of these systems which will benefit retailers and consumers by reducing costs due to shoplifting.
