Method for allocating a mobile record carrier to a fixed data station.

摘要

A mobile data carrier, e.g. an IC identification card used as a key card for vehicles. Locks, has a memory region that is protected and stores a pseudo random code. A second region has a memory used to store a secrete code. When used for the first time a stationary data station responds to the pseudo random code by producing a new secret code that is then entered into the memory. The card is read inductively and operates the lock when the code is identified.
