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.

Abstract: A method for assisting the use of an electronic transaction device. The method includes activating an assisted mode, the activation of the assisted mode being triggered by a detection of a placement of a data entry assistance accessory on a touch screen of the electronic transaction device.

Abstract: A device for entering data, which is configured to be laid down on a touchpad of a terminal. The device for entering data includes an appreciably parallelepiped-shaped plate. The plate includes an upper face, at least one part of which includes a keypad-forming matrix of entry zones, and a lower face. The lower face includes, for each key of the keypad on the upper face, at least one contact zone electrically connected to a corresponding key on the upper face.

Abstract: A system of data entry includes a touch panel of a terminal and a data-entry device to be placed on the touch panel. The touch panel includes a matrix of electrodes having nodes and is managed by a control unit configured carrying out cycles of capacitive scanning and measurement of variance of capacitance of the nodes relative to reference values, detecting meaningful touches on the touch panel and recalibrating reference values. The device includes a plate having a lower face for placing the device on the touch panel; and an upper face with a matrix of entry zones having a thickness enabling a detection of a finger by the touch panel; a flat contact pad electrically conductive and fixedly attached to the lower face; and a network of conductive tracks stretching over at least a part of the upper face and being electrically connected to the contact pad.

Abstract: A magnetic stripe reader includes at least one first sensor and one second sensor respectively delivering a first temporal signal and a second temporal signal proportional to a flux of a magnetic field of the magnetic stripe traveling before the first and second sensors during reading of the stripe by the reader. The first and second sensors are disposed at a pre-determined distance from each other in a sense of travel of the stripe during the reading.

Abstract: A keypad for an electronic data-entry device. The keypad includes: a plurality of keys defining a layer of keys; a connection printed-circuit board having a key-press detection portion having an external face oriented towards the layer of keys and an internal face opposite the external face; for each key of the layer of keys, an interconnection element and at least one pair of contacts on the connection printed-circuit board, the interconnection element being intended for making the electrical connection of the contacts of the pair of contacts when the associated key is pressed. The connection printed-circuit board is a flexible printed-circuit board further including a connecting portion forming a fold beneath the internal face of the key-press detection portion, and the pair of contacts is disposed on the internal face.

Abstract: A system for detecting an intrusion in an electronic device. The system includes at least one optical sensor connected to at least one security module of the electronic device. The optical sensor and the security module are configured to detect a variation in light intensity measured by the optical sensor as compared with a reference light intensity associated with at least one pre-determined light source inside the electronic device. The variation in light intensity represents a risk of intrusion into the electronic device.
