A data input device intended to be affixed to a capacitive touch screen of a terminal includes: a substantially parallelepipedal plate including a lower surface, which is substantially planar, for affixing the device to the touch screen, and an upper surface including an array of input zones that form a keyboard and are configured to enable a finger of a user to be detected by the touch screen when the device is affixed thereto; and at least two contact pads, which are electrically conductive and arranged on the lower surface, and each electrically connected to means for discharging, towards the outside of the touch screen, electric charges concentrated at the contact pads when the device is affixed to and held on the touch screen.

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.

The invention relates to an electronic system comprising a casing consisting of at least first and second casing portions and containing a device for detecting the substitution of the first casing portion. The device comprises a first integrated circuit intended to be fixed to the first casing portion and a second integrated circuit intended to be fixed to the second casing portion. The second circuit is adapted to transmit to the first integrated circuit successive random or pseudo-random digital signals (R). The first integrated circuit is adapted to return to the second integrated circuit, for each digital signal, the first encrypted signature (S) from said digital signal. The second integrated circuit is adapted to determine a second encrypted signature (S') from said digital signal and to detect a substitution of the first casing portion if the first and second encrypted signatures are different.

The invention relates to an electronic circuit comprising: a first random-access data storage element, a processing module designed to delete the first storage element, and an access terminal which is connected to the processing module and receives a first power signal supplied by a first power source external to the electronic circuit. The circuit also includes a second random-access storage element in which a key is stored, said key being used to encrypt the data and a second power source which is built into the electronic circuit and supplies a second power signal to the processing module. The processing module is designed to detect an unauthorized access attempt by comparing the first and second power signals and to delete the key when the processing module is powered by the second power source.
