PROBLEM TO BE SOLVED: To provide a telephone banking security system which can have an access to the bank service in a simple operation while improving the banking security. SOLUTION: A customer can always carry an aural signal transmitter 10. The information given from a bank is previously inputted to the transmitter 10 and then can be easily taken out by the customer in the aural signals. When a telephone circuit is connected to the bank, the customer puts the transmitter 10 close to the receiver of a telephone 8 to transmit the aural signals to the bank via the telephone circuit. At the bank side, the collation of the received information is carried out. Then the bank service is offered to the customer if the coincidence of collation is confirmed. In such constitution, an access operation is facilitated to a bank and no problem occurs for the banking security even though the bank access operation is viewed by a third part. Thereby, the telephone banking safety and reliability can be improved. |
