PROBLEM TO BE SOLVED: To link an input system of commodity data with an electronic receipt system.SOLUTION: A support server accumulates commodity data on a sales commodity determined by a commodity code input from an information terminal in association with a first ID identifying the information terminal. The support server transmits the accumulated commodity data together with the first ID to a processing device, which is a settlement object, determined by data identifying a processing device input from the information terminal. The processing device settles commercial transaction by input of payment data to the commodity data and generates an electronic receipt obtained by digitizing receipt data showing details of the settled commercial transaction. In the case where the electronic receipt received from the processing device is associated with the first ID, an electronic receipt server stores the electronic receipt associated with the first ID.SELECTED DRAWING: Figure 1 |
