Mobile terminal, weighing device, POS terminal, non-transitory computer-readable medium, sales processing system, and sales processing method

A weighing device, comprising:

• a platform on which a product sold by weight is placed to be weighed;
• a display:
• a controller that:
• causes the display to display:
• a first display region that displays first information for a first customer using a mobile terminal, and
• a second display region that displays second information for a second customer not using the mobile terminal, wherein
• the first display region and the second display region are adjacent to each other on a same screen;
• receives an instruction from at least one of the first and second customers via the display;
• and
• a transceiver that establishes the intercommunication with the mobile terminal, wherein
• once the controller receives the instruction to use a weighing function of weighing the product without use of the mobile terminal, or
• once the controller detects that the product is placed on the platform,
• the controller:
• prohibits establishing the intercommunication and then starts weighting of the product sold by weight, and
• permits establishing the intercommunication after the weighting is completed.

A non-transitory computer-readable medium (CRM) that stores instructions that cause a computer to function as a mobile terminal that comprises a storage, a camera, and a display, the instructions causing the computer to:

• acquire a type of a product sold by weight;
• establish intercommunication with a weighing device that weighs the product;
• acquire, from the weighing device, a weight value of the product;
• register, in the storage, product information including a name of the product, the type of the product, and the weight value that is acquired from the weighing device and corresponds to the type of the product;
• and
• cause the display to display on a same screen:
• a first display region that displays an image of the product captured by the camera;
• a second display region that displays a list including a line indicating the registered product information and a price of the product;
• and
• a third display region that displays a current registration status, wherein
• the first display region, the third display region, and the second display region are arranged in this order from an upper part to a bottom part of the screen, and
• with respect to the product whose image is displayed in the first display region but whose weight value has not been acquired, the computer causes the display to add a highlighted line in the list displayed in the second display region, and to display, in the highlighted line, a name of the product requiring weighting and a message informing a user that the weighing is being required.

A non-transitory computer-readable medium (CRM) that stores instructions that cause a computer to function as a weighing device that comprises:

• a platform on which a product sold by weight is placed to be weighed;
• and a display, the instructions causing the computer to:
• cause the display to display,
• a first display region that displays first information for a first customer using a mobile terminal, and
• a second display region that displays second information for a second customer not using the mobile terminal, wherein
• the first display region and the second display region are adjacent to each other on a same screen;
• receive an instruction from at least one of the first and second customers via the display;
• establish the intercommunication with the mobile terminal;
• and
• once the controller receives the instruction to use a weighing function of weighing the product without use of the mobile terminal, or
• once the controller detects that the product is placed on the platform,
• prohibit establishing the intercommunication and then start weighting of the product sold by weight, and
• permit establishing the intercommunication after the weighting is completed.

A sales processing system, comprising:

• a mobile terminal;
• a weighing device that weighs a product sold by weight;
• and
• a POS terminal that performs settlement, wherein
• the mobile terminal comprises:
• a transceiver that establishes intercommunication with the weighing device;
• a processor that:
• acquires a type of the product,
• causes the transceiver to acquire, from the weighing device, a weight value of the product, and
• registers, in a storage, product information including a name of the product, the type of the product, and the weight value that is acquired from the weighing device and corresponds to the type of the product;
• a camera;
• and
• a display, wherein
• the processor causes the display to display on a same screen:
• a first display region that displays an image of the product captured by the camera;
• a second display region that displays a list including a line indicating the registered product information and a price of the product;
• and
• a third display region that displays a current registration status, wherein
• the first display region, the third display region, and the second display region are arranged in this order from an upper part to a bottom part of the screen, and
• with respect to the product whose image is displayed in the first display region but whose weight value has not been acquired, the processor causes the display to add a highlighted line in the list displayed in the second display region, and to display, in the highlighted line, a name of the product requiring weighting and a message informing a user that the weighing is being required,
• the weighing device comprises:
• a transceiver that establishes intercommunication with the mobile terminal, and
• the POS terminal:
• comprises a display, and
• causes the display to display information, obtained via the mobile terminal, on the product of which the weight value has not been acquired.

A sales processing method, comprising:

• acquiring, with a mobile terminal, a type of a product sold by weight;
• establishing, with the mobile terminal, intercommunication with a weighing device that weighs the product;
• transmitting, from the weighing device to the mobile terminal, a weight value of the product;
• registering, in a storage of the mobile terminal, product information including a name of the product, the type of the product, and the weight value that is transmitted from the weighing device and corresponds to the type of the product;
• causing a display of the mobile terminal to display on a same screen:
• a first display region that displays an image of the product captured by a camera of the mobile terminal;
• a second display region that displays a list including a line indicating the registered product information and a price of the product;
• and
• a third display region that displays a current registration status, wherein
• the first display region, the third display region, and the second display region are arranged in this order from an upper part to a bottom part of the screen, and
• with respect to the product whose image is displayed in the first display region but whose weight value has not been acquired, the causing includes causing the display to add a highlighted line in the list displayed in the second display region, and to display, in the highlighted line, a name of the product requiring weighting and a message informing a user that the weighing is being required;
• and
• performing, with a POS terminal, settlement of the product based on the weight value.
