Method and device for acquiring biometric data

A device for collecting biometric data, in particular finger prints, the device having an optically active detector for recording a surface of body areas, and a light source is provided, characterised in that the device has at least one identification arrangement for the superficies finger surface, and characterised in that the identification arrangement for the superficies finger surface comprises at least one or several deviation mirrors, the deviation mirrors being arranged concentrically to an idealized longitudinal axis of the finger, and to image the finger region decisive for the data collection from nail to nail and in an arc angle segment of at least 180° of a circumference of the superficies finger surface, and characterised in that the device has a supporting surface for the hand or the fingers, and in the supporting surface a line sensor is provided which extends over the complete width of the hand, and characterized in that there is relative movement between the line sensor and the hand for recording the hand or finger lines, further characterized in that a sequence of narrowly striped picture segments is produced;

• and a groove is provided in the supporting surface to separate the line sensor and the surface of the hand.
