ABSTRACT:
A security system for electronic circuits (e.g. electronic circuits contained within a secure POS terminal) is provided that is both more tamper resistant, and tamper responsive and less expensive than the prior art epoxy potting. This is achieved by inserting an electrical connector between a first and a second circuit board contained within a case of the POS terminal. The first and the second circuit boards are any type of circuit board known in the art, including both not limited to, rigid circuit boards, flexible circuit boards, printed circuit boards, etc. If the case is opened the connector no longer provides an electrical connection between the first and the second circuit boards, triggering a tamper detection circuit. In some embodiments of the invention, a flexible conductive film is wrapped around the circuit boards and the connector. If a tamperer attempts to penetrate the case of the POS terminal to disable the tamper detection circuit, the circuit on the flexible security film is interrupted, in turn triggering the tamper detection circuit. As a result, the secure POS terminal of the present invention overcomes the limitations of prior art potted terminals. By eliminating the potting process, in fact, the cost of manufacturing the terminal is reduced and there is no need for a special ventilation system. In addition, the circuitry within the terminal can be accessed for repair and maintenance purposes.
