Abstract
A tamper-resistant target wafer (10) for use in an electronic theft detection system has a housing formed with bulges (16 and 22) aligned with each other on opposite sides and which slope continuously downward toward the plane of the target wafer to minimize fulcrum leverage to a prying tool and to enclose a locking mechanism (38) in a manner such that it is protected from attack by plier-like tools.
