ABSTRACT : The invention relates to cards which can be used as parking cards, as bus tickets, and for similar purposes. The cards are provided with strips which bear different parameters (day of the month, month, hour, minutes, etc.), the continuity of the strip being easily dis- ruptible by the application of a mechanical force (such as scratching or the like). The spots which have to be revealed can be covered by a star-shaped figure, of material which can be scratched off, and which is part of the strip. Disruption of the continuity provides a clearly visible indication of the desired parameter and cannot be restored. A number of colors can be used for indicating different parameters.
