Abstract: The device for checking electronic cards includes a base in which conductive nails are arranged pointing upwards, and a cover, also fitted with nails pointing downwards in the closed cover position. The cover is mobile in horizontal translation between an open position and an intermediate position. The device can also include a vertical translation mechanism capable of bringing the nails arranged in the cover closer to the nails arranged in the base so as to allow contact of the nails on the two faces of an electronic card. The invention also relates to a method of opening and a method of closing such a device.
