Abstract
A portable data carrier () comprises an executable training module () which provides in a memory () of the data carrier () a reference model (; M) for the biometric recognition of a user of the data carrier () by a recognition module (), whereby a biometric comparison vector () which lies within the acceptance range (A) of the reference model (; M) is accepted by the recognition module () as coming from the user. In so doing, the training module () defines the reference model (; M) by model nodes (P, P-P) which are formed from biometric reference vectors (; N) in each case coming from the user, whereby a new model node (P, P-P) is added to the reference model (; M) when the associated reference vector (; N) lies outside the acceptance range (A) of the reference model (; M).
