Magnetic head for payment terminal
The invention relates to a magnetic reading head to be mounted in a terminal, said head having a generally rectangular parallelepiped shape and comprising a face for reading data coming from a magnetic stripe, said face comprising at least one component for reading data coming from a magnetic stripe. According to the invention, such a magnetic reading head comprises at least one flexible printed circuit board for protection against electromagnetic disturbances, said flexible printed circuit board being positioned on at least one face different from said reading face.
1. A magnetic reading head to be mounted in a terminal, said magnetic reading head having a generally rectangular parallelepiped shape and comprising a reading face for reading data coming from a magnetic stripe, said reading face comprising at least one component for reading data coming from the magnetic stripe, said magnetic reading head comprising at least one flexible printed circuit for protection against electromagnetic disturbances, said at least one flexible printed circuit being positioned on at least one face different from said reading face.
2. The magnetic reading head of claim 1 , wherein said at least one flexible printed circuit board covers three faces of said magnetic reading head.
3. The magnetic reading head of claim 1 , wherein said at least one flexible printed circuit board covers four faces of said magnetic reading head.
4. The magnetic reading head of claim 1 , wherein said at least one flexible printed circuit board covers five faces of said magnetic reading head.
5. The magnetic reading head of claim 1 , wherein said at least one flexible printed circuit board is constituted by an electromagnetic shielding.
6. The magnetic reading head of claim 5 , wherein said electromagnetic shielding is a Faraday cage.
7. A payment terminal comprising at least one set of components for reading data coming from a card comprising a magnetic stripe and comprising a magnetic reading head, the magnetic reading head comprising a generally rectangular parallelepiped shape and comprising a reading face for reading data coming from the magnetic stripe, said reading face comprising at least one component for reading data coming from the magnetic stripe, said magnetic reading head comprising at least one flexible printed circuit for protection against electromagnetic disturbances, said at least one flexible printed circuit being positioned on at least one face different from said reading face.
8. The payment terminal of claim 7 , wherein said magnetic reading head is positioned within an aperture of a first lateral wall and wherein a second lateral wall is situated facing the first lateral wall to define a slot for the insertion of the card comprising the magnetic stripe, said second lateral wall comprising at least one electromagnetic isolation device positioned so as to be facing the reading face of the magnetic reading head.
9. The payment terminal of claim 8 , wherein said at least one electromagnetic isolation device takes the form of a flexible printed circuit board with a width and a height at least equal to a corresponding width and a corresponding height, respectively, of the reading face of the magnetic reading head.
