Abstract: An electronic circuit, which includes: a printed circuit, at least one first electronic component and at least one second electronic component. The at least one first electronic component includes an interconnection face provided with electrical interconnections brazed on an external face of the printed circuit. The interconnection face is opposite the external face. The brazed electrical interconnections form at least one space between the interconnection face and the external face. The at least one second electronic component is brazed on the external face and is at least partly housed in the at least one space.

Abstract: A support element of a keypad included in a keyboard of a data input device. The support element puts at least one dummy key of a printed circuit board under pressure.

Abstract: A component for holding a magnetic reading head, and a slotted magnetic card reader comprising a magnetic card reader held by such a component. The holding device includes a single component having at least one perforated plane surface appreciably of the same length and same width as the rear face of the housing of the reading head. The reading head also has two surfaces perpendicular to the perforated plane surface that form two mutually parallel lateral uprights intended to grip the housing of the magnetic reading head, and at least one affixation point.

Abstract: Component for the protection of sensitive signals, corresponding device and method, wherein the invention relates to an electronic component that comprises: an envelope forming a package; a printed circuit board; and a plurality of balls integrated into a ball grid array (BGA); said printed circuit board comprising at least one circuit defining at least one guard ring.

Abstract: A terminal includes first and second communication modules for communicating with a personal device for performing transactions, called a transactional device. The first communication module includes a contact reading interface, and the second communication module includes a contact-free reading interface. The terminal also includes a detection module including: at least one transactional device position sensor, delivering an item of data representative of a position of a transactional device relative to the terminal; and at least one control module for controlling at least one communication module of the first and second communication modules, the at least one control module activating the communication module on the basis of the item of data representative of the position of the transactional device.
