PURPOSE:To improve an operability viewed from a customer by checking a cipher code without performing a communication with a center by comparing the cipher code inputted at first with the cipher code inputted since the second time by a transaction device. CONSTITUTION:For example, at the time of the transaction in which a cipher code input is operated plural times such as a payment transaction after a balance inquiry, the first cipher code check is operated by a center 2, and the inputted cipher code is stored in a transaction device (for example, automatic money paying and receiving machine) 1. Then, at the time of receiving a transaction permission signal from a center 1 by the first communication with the center 2, the cipher code inputted at first is recognized as the correct one, and at the time of the input of the cipher code since the second time, the cipher code inputted by a customer is compared and collated with the stored cipher code. Therefore, at the time of the input of the cipher code since the second time, it is not necessary to communicate with the center 2 every time just like convention, an input response to the customer can be fastened, and the operability viewed from the customer can be improved. |
