Abstract
A magnetic card reader comprising a groove for shifting of a magnetic card and a magnetic read head mounted on a first printed-circuit board so as to enable reading of a magnetic stripe of the magnetic card. The magnetic read head has a tunnel magnetoresistance sensor called a TMR magnetic sensor positioned in a recess of a side wall of the groove.

A magnetic card reader comprising:
- a groove configured to enable shifting of a magnetic card in the groove;
- and
- a magnetic read head mounted on a first printed-circuit board so as to enable reading of a magnetic stripe of the magnetic card, wherein said magnetic read head comprises a tunnel magnetoresistance sensor called a TMR magnetic sensor positioned in a passage recess of a side wall of said groove, said side wall taking the form of a wall made of dissipative plastic at least partially overlaying said first printed-circuit board, said first printed-circuit board comprising at least one electrostatic discharge track in contact with said side wall.
A magnetic card reader comprising:
- a groove configured to enable shifting of a magnetic card in the groove;
- and
- a magnetic read head mounted on a first printed-circuit board so as to enable reading of a magnetic stripe of the magnetic card, wherein said magnetic read head comprises a tunnel magnetoresistance sensor called a TMR magnetic sensor positioned in a recess of a side wall of said groove, and wherein said side wall is formed at least partially by said first printed-circuit board, said recess being a blind recess of said first printed-circuit board.
A magnetic card reader comprising:
- a groove configured to enable shifting of a magnetic card in the groove;
- a first printed-circuit board;
- a magnetic read head mounted on the first printed-circuit board so as to enable reading of a magnetic stripe of the magnetic card, wherein said magnetic read head comprises a tunnel magnetoresistance sensor called a TMR magnetic sensor positioned in a recess of a side wall of said groove;
- and
- at least one electrostatic discharge track comprised on said first printed-circuit board and positioned in said recess, about said TMR magnetic sensor.
