The system can also contain information database about the transactions made with cards (6), interface (10) working as an intermediary in providing information on available payment terminals and their geographical position, location module (14) providing the system with the information on terminal locations and calculation module (3) calculating the time-spatial distance of the current transaction from the previous transaction made with the same card via payment terminal or the spatial distance between the payment terminal in which the |
