Here, the control parameters are, for example, data for designating which digit of the data read from the credit card is a credit member number when performing credit processing, and a product indicating a merchandise that can be handled. It is a code or a customer code of a defective card, and also includes information for switching whether to register only the quantity or the quantity and the amount of money depending on the type of the card when performing the registration process.

[Problems to be Solved by the Invention] Although some of the above-mentioned POS terminal devices have been used since the beginning of installation of the POS system, there are some that are added or updated thereafter. As described above, in the POS terminal device installed later, the above-mentioned control parameters may be slightly changed, and one POS system has POS terminal devices having different control parameters.

By the way, the above-mentioned control parameters need to be updated when the operating mode of the system is changed midway. However, in the conventional POS system, the storage data of the POS terminal device is updated by simply sending the update data from the center device, so
Update data will be sent to the POS terminal. In this case, the data is transmitted to the POS terminal device that does not need to change the control parameter, which is wasteful. In order to eliminate such waste, the center device
Although it is conceivable to provide a management table that manages the respective installation dates and terminal numbers of the POS terminal devices, there is a problem that it takes time and labor.

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