Abstract
In a method for recording reference fingerprint data for a person, at least two fingerprint images are recorded that depict at least partially different areas of one and the same finger of the person. Data from these images is stored in at least two alternative sets of reference fingerprint data that are to be used in checking the identity of the person. This method makes it possible to use a small sensor that only records partial fingerprints, both when recording reference data and when verifying, without the person having to make repeated attempts during the verification in order for the sensor to record the same area on the finger both when recording reference data and during the verification. In addition, a method is described for checking identity, in which method the fact is utilized that there are alternative sets of reference fingerprint data, and devices for carrying out the methods.
