Abstract

PURPOSE:To slash communication cost by deciding whether identification data that a center device transmits is the same as stored identification data and transmitting stored update data to a POS terminal equipment. CONSTITUTION:The decision is made whether the identification data which is transmitted from the POS terminal equipment 1 together with transaction data and identifies contents of data required for transaction processings is the same as the identification data which is stored in the center device 2 and identifies contents of data required for transaction processing. Only if they disagree, the data which is stored in the center device 2 and required for transaction processing is transmitted to the POS terminal equipment 1. Hence update data can be transmitted only to the POS terminal requiring modification without providing a control table controlling the data that the POS terminals require for transaction processing. Thus the communication cost can be slashed.

Even within the system, there are POS terminal devices with poor control parameters.

By the way, the above-mentioned control parameters need to be updated if the operating mode of the system is changed during the process. However, in conventional POS systems, the data stored in the POS terminal device is updated by simply sending update data from the center device, so the update data is sent to all POS terminal devices. . With this, there is no need to change the control parameters.
Since data will also be sent to the OS terminal device, there will be waste. In order to eliminate this waste,
It is conceivable to create a management table, %, B2, for managing the establishment date and death number of each POS terminal device in the center device, but this has the problem of requiring time and effort.

Therefore, the present invention has been made in order to solve the above-mentioned problems, and provides a transaction processing device that allows updating of control parameters only for those that require changes in the control parameters of a POS terminal device. The purpose is to provide the following.
