Claim 7

A transaction safety system according to claim 3, wherein the special code is included when necessary in the transaction data which is needed for processing a deposit transaction using a passbook, and wherein said discriminating portion determines whether the special code is included in the transaction data which is input for the deposit transaction.

Claim 8

A transaction safety system according to claim 2, wherein the output portion includes a printing device, operatively connected to said controlling means, for printing a result of the transaction onto a passbook, said printing device printing the result of the transaction based on text output by the processing device and sent via the subscriber's telephone line.

Claim 9
