Abstract
A non-contact-type access authorization reading device on an access control apparatus (1) reads an access authorization stored in a data carrier (9) received by an object (ski 7) which the user carries near the ground. The reading device has an antenna (11) disposed in the ground area and is connected to an evaluation unit which releases the access (2) upon reading of a valid access authorization. To provide the data carrier (9) with an access authorization, a copy-over data carrier (12) is acquired which stores a coding authorization for an access authorization. A copy-over reading device reads the coding authorization on the copy-over data carrier (12), and a coding device contactlessly codes the access authorization on the access authorization data carrier (9), the coding authorization being deleted after coding.
