The invention concerns a holder 2 for an identification card, on whose front side an interchangeable identification card 1 can be inserted. A spring-loaded yo- yo 5 is secured to the back side of the holder 2 placed so that the yo-yo 5 remains partly or entirely invisible when the card with the holder is viewed from the front. When the yo-yo is integrated with the card holder, it forms a small, easily portable and easily manipulable unit which can be moved away from the user into proximity of the code reader of the electrical lock without undoing the suspension. <IMAGE>
