| 摘要 |
The invention concerns a reading head (80) for reading or authenticating a magnetic code or signature (79), comprising a source of magnetic field (81) arranged for magnetising the signature magnetic elements (E1, E2, E3) while reading, and at least a first (82) and second (85) magnetoresistive components arranged on either side of the source of magnetic field (81) along a reading axis (A1A1'), for sensing non-volatile magnetic elements and slightly volatile magnetic elements. |
