FIELD: information technologies.
SUBSTANCE: portable data carrier contains carrier memory (12) for storage of data, containing biometric template (13) and set of commands (15), in compliance with which operation of portable data carrier is organised to perform the function that depends on the field of application, in which portable data carrier is used, and also communication facility (11) of carrier for contact-free reception and transfer of data. Portable data carrier is characterised by the fact that it additionally contains processor facility (16) of carrier to compare biometric template to biometric sample (23) received from external device (20), and by the fact that it is arranged with the possibility to perform process of acknowledgement with external device, and to perform specified function and transfer its result to outer device only in case, when biometric sample matches biometric template.
EFFECT: reliable and safe portable data carrier, which may be used as identification facility.
