Abstract

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.

Claims

1. A magnetic stripe reading device comprising:

a magnetic head assembly including;

a mounting element defining a circumferential anti-tampering enclosure; and

at 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; 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 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.

2. A magnetic stripe reading device according to claim 1 and wherein said protective layer and said at least one anti-tampering contact array are both located on the same plane.

3. A magnetic stripe reading device according to claim 2 and wherein said protective layer surrounds said at least one anti-tampering contact array.

4. A magnetic stripe reading device according to claim 1 and wherein said protective layer surrounds said at least one anti-tampering contact array.

5. A magnetic stripe reading device according to claim 1 and also comprising anti-tamper circuitry coupled via said flat cable to said protective layer and to said at least two electrical contacts and providing a tampering alarm indication when said at least two electrical contacts are not in galvanic contact and when said at least one protective grid is compromised.

6. A magnetic stripe reading device according to claim 5 and wherein said flat cable is also provided with protective grids extending along first and second opposite flat surfaces thereof and coupled to said anti-tamper circuitry, thereby surrounding at least a portion of said cable including elements which carry said electrical signals from said at least one information reading sensor.

7. A magnetic stripe reading device according to claim 1 and wherein said flat cable is also provided with protective grids extending along first and second opposite flat surfaces thereof, thereby surrounding at least a portion of said cable including elements which carry said electrical signals from said at least one information reading sensor.

8. A magnetic stripe reading device according to claim 1 and wherein said protective layer and said flat cable are integrally formed.

9. A point-of-sale device comprising:

a housing defining a keypad array location at which an array of keys are located and a display location at which a display is located;

a magnetic card reader assembly associated with the housing and including a slot and magnetic stripe reading device, said magnetic stripe reading device comprising;

a magnetic head assembly including;

a mounting element defining a circumferential anti-tampering enclosure; and

at 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 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 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.

10. A point-of-sale device according to claim 9 and wherein said protective layer and said at least one anti-tampering contact array are both located on the same plane.

11. A point-of-sale device according to claim 10 and wherein said protective layer surrounds said at least one anti-tampering contact array.

12. A point-of-sale device according to claim 9 and wherein said protective layer surrounds said at least one anti-tampering contact array.

13. A point-of-sale device according to claim 9 and wherein said magnetic stripe reading device also includes anti-tamper circuitry coupled via said flat cable to said protective layer and to said at least two electrical contacts and providing a tampering alarm indication when said at least two electrical contacts are not in galvanic contact and when said at least one protective grid is compromised.

14. A point-of-sale device according to claim 13 and wherein said flat cable is also provided with protective grids extending along first and second opposite flat surfaces thereof, thereby surrounding at least a portion of said cable including elements which carry said electrical signals from said at least one information reading sensor.

15. A point-of-sale device according to claim 9 and wherein said flat cable is also provided with protective grids extending along first and second opposite flat surfaces thereof and coupled to said anti-tamper circuitry, thereby surrounding at least a portion of said cable including elements which carry said electrical signals from said at least one information reading sensor.

16. A point-of-sale device according to claim 9 and wherein said protective layer and said flat cable are integrally formed.
