Abstract
An apparatus for reading authorization cards with a bar code has a housing with an insertion slot for inserting the card and at least one reading head in the housing for scanning the bar code in a line perpendicular to the insertion direction of the card. The space in the housing is formed to be so long that the card is insertable further beyond the scan line of the reading head by a path (d) that is greater than the distance (c′) between the leading edge of the card and the end of the bar code field facing away from the leading edge. This permits reading of cards with different lengths (a) and different positions (c′) of the bar code field.
