Abstract: A portable electrical power supply device includes a battery, cables and a female connector to which is attached a cover aimed at attaching the connector to the battery. This cover notably attaches the female connector and the battery as such. This gives a compact, consistent and rigid assembly. No separate handling operations need to be planned to insert the female connector into the male connector and insert the battery into its housing. Besides, in at least certain embodiments, the rigid cover is shaped so that it does not take up a volume greater than that of the battery without a cover.

Abstract: A payment terminal includes a slot for inserting a magnetic memory card. A general display plane of the terminal, formed by a keyboard and/or a terminal screen, forms a non-zero angle with a general positioning surface of the terminal. The bottom plane of the insertion slot of a magnetic memory card is appreciably parallel to the plane on which the terminal is positioned.

Abstract: A housing of a terminal is formed by at least one lower cover and an upper cover. The housing the lower cover and upper cover are fixed together in an articulated manner, the articulated fixing being able to take up at least one position closing the housing and a position opening the housing, in which the lower cover and upper cover are joined together.
