Access control using license plate recognition is used today in a wide variety of areas, such as entrances to company premises, in security zones, petrol stations, parking garages or in fleet management. In addition to the obvious safety aspect, the comfort for the   driver also plays an increasingly important role.

The access control procedures using number plate recognition or vehicle license plate recognition are based on image processing methods. The digital or digitized images of a video camera are evaluated using complex algorithms based on license plate information so that the data then obtained can be automatically used for different applications.
