FIELD: physics, computer engineering.
SUBSTANCE: invention relates to methods and devices for making payment transactions using biometric parameters of a customer. In the method, during customer registration, at least three fingerprint copies are scanned and entered into a database, one of which is used during payment, the other when blocking (terminating) payment and the third for generating "alarm" commands, with assignment of a unique code associated with a bankcard or the bank account of the customer. The customer enters the payment sum at a terminal and places a finger on the scanner. The obtained fingerprint copy is identified from the database of customers and upon positive identification, a unique code and the payment sum are sent to the bank, where if there is sufficient balance on the account of the customer, the payment sum is deducted from the account of the customer and a payment confirmation is sent to the terminal. The device implements said method.
EFFECT: high reliability of customer identification and protecting the customer from forced payment.
