Abstract
This invention relates to a method and apparatus for deactivating EAS markers. The device utilizes deactivating magnetic fields created by energizing electrical coils to deactivate electronic article surveillance markers. It consists of housing having an internal structure holding an electrical coil arrangement. The coil arrangement comprises two electrical coils that are arranged essentially coplanar, arranged side-by-side. A third electrical coil is arranged such that each of its windings wraps around both the first and said second electrical coils. Current flowing through the coils generates a composite deactivating magnetic field above the housing. This deactivating magnetic field allows deactivation of a tag swept in any orientation, and does not require the tag to come into physical contact with the deactivating device. Flush mounting conserves space, allowing for ease of merchandise movement over the counter. A distinctive sound indicates the presence and deactivation of the label.
