SUBSTANCE: system includes a payment processing system adapted to convert a protected account number into the real account number of the user in response to the payment processing system receiving a request to authorise a transaction, which contains the protected account number. The payment processing system determines the real account number of the user associated with the protected account number, and also verifies that the request to authorise the transaction is associated with a non-contact type of a wireless transaction. The method is realised by the system described above.
EFFECT: high security when making financial transaction owing to use of protected account numbers from portable non-contact user devices.
