Abstract: Card holder, especially for plastic cards with readable data unit, such as credit cards and/or smart cards, with externally hinged covers (1, 2) made of a rather rigid material constituting the walls of the card holder as each of the covers (1, 2) at or near the ends which are not hinged together, has at least one mutually conjunctive locking mechanism (4) to hold the card holder locked when it is not being used. The card holder has, two paired, mainly identical, holding devices (5, 6) at opposite sides, said holding devices (5, 6), preferably, being hinged together with the covers (1, 2), and having a number of paired, opposing holding surfaces (11, 12) to enclose an area along the side edges of cards of the above mentioned type. The holding surfaces (11, 12) are mainly parallel to each other both when the card holder is open and closed.
