A method for determination of the authorisation of a person to use a portable data support (10), with a checking device (32) is disclosed. A biometric feature of the authorised person is used by the checking device (32) to reproduce a data support code also stored on the data support (10) on a utilisation occurring. The data support code (DTK, CV) is formed by modification of a reference data set (BIOR) derived from the biometric feature. The data support code (DTK, CV) unequivocally assigns the data support (10) to a present authorised person. As the biometric feature is only used in modified form it is not possible to simulate a data support (10) merely with knowledge of the biometric reference data set (BIOR). |
