• receiving at the processor of the portable terminal simplified settlement data and ID data from a settlement processing apparatus including a point of sale terminal configured to process the sale of goods, the simplified settlement data is derived from the settlement data and includes a transaction date;
• recording in a recording unit of the portable terminal the simplified settlement data in association with the ID data received from the settlement processing apparatus;
• displaying on the display unit of the portable terminal the simplified settlement data that has been recorded;
• in response to the user entering the command into the portable terminal requesting that the electronic receipt be downloaded to the portable terminal, generating a download command for downloading to the portable terminal the electronic receipt related to the simplified settlement data displayed on the display unit;
• generating, by the processor of the portable terminal, an address identifying a location of an electronic receipt server where the electronic receipt is recorded from the ID data recorded in association with the simplified settlement data;
• recording in the memory the electronic receipt downloaded from the electronic receipt server;
• and
• displaying the electronic receipt on the display unit of the portable terminal;
• wherein the portable terminal is configured to receive from a server memory of the electronic receipt server the electronic receipt stored in the server memory in association with the ID data in response to the user selecting the simplified settlement data displayed on the portable terminal corresponding to the electronic receipt, thereby saving storage space on the portable terminal because the electronic receipt, which requires more storage space than the simplified settlement data, is stored remotely on the server memory until the user requests the electronic receipt by selecting the corresponding simplified settlement data displayed on the portable terminal.
