FIELD: medicine.
SUBSTANCE: invention relates to devices for papillary pattern registration and can be used in systems of access limiting for identification of personality by finger prints. Device contains set of two prisms, each of which is located between light source and projection system and is optically connected with them, successively placed and optically connected to each other for each of the prisms light source, projection system and system of photoreceiving elements, electrically connected to processing unit. Prism sides, perceiving finger prints, are located relative to each other in such way, that their longitudinal symmetry axes cross at angle lying within the range 60-120 degrees, also there is a system for control of coincidence of pressed to prisms fingers of personality's left and right hands.
EFFECT: application of claimed invention allows to obtain possibility of simultaneous registration of prints of any coinciding fingers of personality's left and right hands with possibility to control finger coincidence.
