Abstract: A card holder for carrying a card and movable between card hiding, showing and protruding configurations. The card holder includes a casing defining a front aperture and a card slit, and a front cover for selectively covering the front aperture. In the card hiding configuration, the front cover obstructs the front aperture and the card is entirely contained in the casing. In the card showing configuration, the front cover is retracted from at least part of the front aperture and the card is entirely contained in the casing. In the card protruding configuration, part of the card protrudes from the casing through the card slit.

Abstract: A card holder for securely linking together an identification card to a validation card so as to prevent fraudulent removal of the identification and validation cards once the latter have been inserted into the card holder. The card holder defines a generally flat and hollow casing. The identification card is adapted to be secured within the casing so that it can be visualized through a window aperture formed therein. A carriage component defining a carriage slot is slidably mounted within the casing inner volume over the first card. The carriage slot is provided with protrusions adapted to cooperate with corresponding notches formed in a marginal upper segment of the validation card for securing the latter to the carriage.

Abstract: A card holder for securely linking together an identification card to a validation card so as to prevent fraudulent removal of the identification and validation cards once the latter have been inserted into the card holder. The card holder defines a generally flat and hollow casing having a casing front wall, an opposed casing rear wall, a casing top wall, an opposed casing bottom wall and a pair of casing side walls. The casing front wall has a window aperture extending therethrough. The casing bottom wall has a bottom wall slot extending therethrough. The first card is adapted to be secured within the casing so that it can be visualized through the window aperture. A carriage component defining a carriage slot is slidably mounted within the casing inner volume over the first card.
