A parking system includes at least one first, near-field broadcasting device emitting a first radio field and at least one second, near-field broadcasting device emitting a second radio field. The system operates at least one access device. The first near-field broadcasting device transmits a first access data record, which is a function of a second access data record transmitted by the second near-field broadcasting device. An evaluation device identifies an associated access device in the system based on an evaluation of the functional relationship between the first access data record and the second access data record.
