<p>A POS device (12-1, 12-2, 12-3) functioning as a store complex checkout apparatus reads an information storage medium (16-11, 16-12, etc) storing at least a product provision store code and a product code attached to products (14-11, 14-12, etc) of its own (e.g. 10-1) and other stores (10-2, 10-3) using a medium reading unit, refers to product master file information (22-1, 22-2, 22-3) and performs checkout when a product checkout processing unit identifies the code as its own store (e.g. 10-1) from information read from the information storage medium, and refers to corresponding master file information of another store (10-2, 10-3) and performs checkout if the product checkout processing unit identifies the code as the code of the other store, causing a transaction management unit (46) to generate and store transaction information including a store code and the product provision store code. Further, a store-to-store information send/receive processing unit (48) performs checkout processing for the transaction amount with a store checkout apparatus of other stores based on the transaction information. <IMAGE> <IMAGE></p> |
