Abstract: An inspection apparatus for optical inspection of a card insertion slot of a card reader. The apparatus includes a housing holding a magnifier lens assembly, the magnifier lens assembly being mounted through the housing, from a back face to a front face of the housing; at least two guiding elements, protruding outwards the front face of the housing; and at least two light sources located on a front side of the inspection apparatus. The inspection apparatus is further configured so that the at least two guiding elements, the at least two light sources, and an optical axis of the magnifier lens assembly are substantially contained in a same plane.

Abstract: A secure display device is designed to display on a screen a first set of information edited by an open operating system. A secure operating system resident in a dedicated circuit edits a second set of information. A filter allocates, independently of the open operating system, a first zone of the screen to the first set of information and a second zone of the screen to the second set of information. The zones and can have a non-zero intersection and any value. A real video memory is used for transferring the two sets of information to the screen under the sole control of the secure operating system so as to produce a secure display of the second set of information.
