Abstract

An electronic device has an opening for up to two data carrier devices or, respectively, chip cards with row-type contact surfaces positioned alongside one another. The devices or, cards are stackable over one another in offset fashion. In a region of the terminal side lying opposite the plug opening it comprises two rows of contact springs lying next to one another, said rows being spatially offset upwards by the height of a card, and also offset in the insertion direction in a manner corresponding to the card offset. The resilient ends at the plug side of these contact springs respectively contact the contact surfaces of inserted data carriers from above.
