GOODS SALE DATA PROCESSOR AND CONTROL METHOD THEREOF

摘要

A goods sale data processor performs a process of registering goods to be transacted. Reserved registering information to be reserved is stored. The reserved registering information to be reserved is updated and stored in a storage unit when the registering process is reserved, the registering process is being performed, and when the updated reserved registering information is notified from another goods sale data processor. The updated reserved registering information is notified to another goods sale data processor when the processor reserves the registering process. When the registering process is requested to restart, the selection of the reserved registering information used to restart the registering process out of the reserved registering information stored in the storage unit is received and the registering process is restarted using the selected reserved registering information.
