Method for securing data communications between a data medium and a vehicle and a system for monitoring the operation of a vehicle

摘要

A data medium 2 which e.g. is necessary for the use of a vehicle contains personal and other data which can be deposited onto the data medium in a data communications device (8) remote from the vehicle. In a data communications device (26) fixed to the vehicle, personal data can be inputted. A readout of the other data e.g. budget data or for the electronic anti-theft device which must be overridden, takes place only if the comparison in the vehicle of the inputted personal data and the personal data stored on the data medium is positive.
