Abstract: A memory card reader body includes proposed, on an internal face, a receiving recess to receive a memory card connector. The receiving recess has electrically conductive tracks forming a protective mesh for the memory card connector. The conductive tracks are such that they also extend on an external face of the memory card reader body through vias passing through the internal and external faces.

Abstract: A method for managing, by device, a matrix of keys, including at least one line and at least two columns, each key making short circuiting a line and a column when pressed. The method includes a sweeping phase, including, for each line: writing a predetermined logic value in the line; and for each column, reading a logic value in the column and comparing the read logic value and the predetermined logic value. For each line processed: the writing step is carried out during a predetermined time interval. For each column, the reading step is carried out during a first portion of the time interval. The sweeping phase further includes, for each column, writing the predetermined logic value in the column during a second portion of the predetermined time interval. The predetermined time interval is equal to the sum of the durations of the first and second portions.

Abstract: There is proposed a method of managing an array of keys by a device, each key pressed short-circuiting a row and a column of the array. During at least part of a time slot lying between two successive iterations of a sweep phase, the device performs a first protection mechanism, including reading a logic value on at least one row or column, and detecting an attempted illicit sweep as a function of the logic value read, and/or a second protection mechanism, including writing an arbitrary logic value, equal to or different from the predetermined logic value, on at least one row or column, so as to prevent an attempted illicit sweep.

Abstract: A protection device is provided, which includes a detection circuit for detecting a short-circuit between at least two output branches of a magnetic reading head. Each of the output branches is able to convey a signal read by the reading head on a track of a magnetic card and the detection circuit is able to detect a short-circuit during the reading of at least one track of a magnetic card.

Abstract: A device is provided for logging data in Braille. The device includes a touch-sensitive surface and is configured to detect a plurality of pressures on the touch-sensitive surface, wherein the plurality of pressures form a Braille character, construct an image formed from the points associated with the plurality of pressures; and recognize the Braille character based on an analysis of the image.

Abstract: A portable device is provided, which includes a touch screen and at least one area bearing reference information, referred to as a reference area, which can be identified by detecting a variation in the surface state on the device.

Abstract: A universal electronic payment terminal base comprising an application and transaction microprocessor (4), with its power supply source (8) and being capable of receiving information identifying memory card holders, and a reader (6) of these cards controlled by the microprocessor (4). The source (8) also serves for programming the cards and delivers a voltage at most equal to the smallest of the programming voltages required. Between the low weight source (8) and the reader (6) a voltage booster (51) is provided for boosting the voltage to a constant level higher than the largest of the programming voltages, and a step by step voltage dropper (53) controlled by a variable cyclic ratio pulse generator (36).
