Magnetic stripe reading device

摘要

A magnetic stripe reading device including a magnetic head assembly including a mounting element defining a circumferential anti-tampering enclosure and at least one information reading sensor having output contacts, a protective layer including at least one protective grid and at least one anti-tampering contact array including at least two electrical contacts, at least one resiliently deformable conductive element arranged to selectably provide a galvanic interconnection between the electrical contacts, a closure element fixed to the assembly in a secure orientation to displace the deformable conductive element into galvanic interconnection contact with the electrical contacts, whereby tampering with the closure element causes the deformable conductive element to break the galvanic interconnection contact and a flat cable coupled to the output contacts, to the protective layer and to the electrical contacts and carrying electrical signals useful for providing a tampering alarm indication when the electrical contacts are not in galvanic contact.

1. A magnetic stripe reading device comprising:
a magnetic head assembly including:
a mounting element defining a circumferential anti-tampering enclosure; andat least one information reading sensor having output contacts, said at least one information reading sensor being mounted in said mounting element; a protective layer including:
at least one protective grid; andat least one anti-tampering contact array including at least two electrical contacts; at least one resiliently deformable conductive element arranged to selectably provide a galvanic interconnection between said at least two electrical contacts of said at least one anti-tampering contact array; a closure element fixed to said magnetic head assembly in a secure orientation such that said closure element displaces said at least one resilient deformable conductive element into galvanic interconnection contact with said at least two electrical contacts of said at least one anti-tampering contact array, whereby tampering with said closure element causes said at least one resilient deformable conductive element to break said galvanic interconnection contact with said at least two electrical contacts of said at least one anti-tampering contact array; and a flat cable coupled to said output contacts of said at least one information reading sensor and carrying electrical signals provided thereby and also coupled to said protective layer and to said at least two electrical contacts and carrying electrical signals useful for providing a tampering alarm indication when said at least two electrical contacts are not in galvanic contact.
