  • Publication number: 20210166212
    Abstract: A commodity sales processing system in an embodiment includes a first server, configured to connect to a customer information terminal via a first network, and a second server, configured to connect to a store code reading apparatus. The first server associates a first unique code for the customer information terminal with a second unique code for the store code reading apparatus. The second server registers products in a sales transaction associated with the second unique code. The products are identified by a commodity code read by the store code reading apparatus and then received by the second server via the second network. The first server is configured to transmit, via the first network, product information for the products registered in the sales transaction to the customer information terminal associated with the first unique code.
