  • Patent number: 4695845
    Abstract: A theft-detection wafer attachment system that increases the tamper-resistance of theft-detection wafers used in the retail apparel industry includes a disc-like theft-detection wafer of the type having a central projection for receiving a tack-like fastener and a concentric ridge that surrounded the projection. A shield member is mounted over the projection and includes a counterbore for receiving a tack-like fastener. The outside diameter of the shield member is less than the diameter of the concentric ridge to eliminate the opportunity to use the ridge as a fulcrum for prying the secured fastener from the wafer. Additionally, the counterbore receives the head of the fastener to deny access to the fastener head with a prying tool. The exposed portions of the shield member are preferably formed with tapered surface to prevent gripping with conventional gripping tools.
