Abstract
In a device for access control, the authorizations are stored on tickets in the form of a barcode. A reader unit is connected to an evaluating unit and controls devices that signal and/or block access. The reader unit has an insertion zone for a ticket wherein the insertion zone is larger than a ticket dimension. A multidirectional laser scanner scans the entire insertion zone in several lines oriented at an oblique angle relative to one another. The device can be used with different ticket formats such as air-travel tickets and check cards.
