Abstract: A method of processing a purchase transaction includes generating a transaction file containing a product code, which is transmitted from a user computing device when an image of a product code identifier is captured by the user computing device, a first user ID of the customer, and an indicator of whether or not the customer has opted in to receive electronic receipts. The method further includes generating an electronic receipt based on the transaction file, storing a conversion table containing the first and second user IDs of the customer, converting the first user ID contained in the transaction file to the second user ID based on the conversion table, when the indicator indicates that the customer has opted in, and storing the electronic receipt in association with the second user ID. The electronic receipt is transmitted in response to a request for electronic receipts associated with the second user ID.

Abstract: A method of distributing purchase recommendations to a user terminal and tracking their effectiveness includes receiving an image of a product code captured from a user terminal at a store server through a wireless device, the store server connected to a first database from which the store server retrieves product information relating to the product code, the product information including one or more recommended products associated with the product, and a second database that tracks effectiveness of recommendations for each product, and transmitting the product information to the user terminal through the wireless device. The presence of at least one recommended product in the product information causes the self-registration program in the user terminal to display a user interface for accessing information about the recommended product on the user terminal and enable the store server to update the second database by tracking the user inputs made through the user interface.

Abstract: A method for unifying formats of electronic receipts, includes the steps of receiving, from a first processing device, first electronic receipt data in a structured data format, the first electronic receipt data containing a user ID and transaction content corresponding to one transaction, receiving, from a second processing device, second electronic receipt data in a non-structured data format, converting the received second electronic receipt data into the structured data format, the converted second electronic receipt data containing a user ID and transaction content corresponding to one transaction, and storing the first electronic receipt data in the structured data format and the second electronic receipt data in the structured data format in a table, each entry of the table containing a user ID and transaction content corresponding to one transaction.

Abstract: A server for providing nutrition data to a user includes a communication interface, a memory, and a processor. The server receives from a user device a request for nutrition information of food and drink purchased by the user and user identification. The server determines a time period of the requested nutrition information. The server retrieves receipt data corresponding to the user identification and determined time period. The receipt data includes a first data for identifying the food and drink purchased by the user. The server also retrieves nutrition data corresponding to the foods and drink purchased by the user. The server generates and sends to the user device an image data that includes the nutrition.

Abstract: A server for providing nutrition data to a user includes a communication interface, a memory, and a processor. The server receives from a user device a request for nutrition information of food and drink purchased by the user and user identification. The server retrieves receipt data corresponding to the user identification including a first data for identifying the food and drink purchased by the user. The server also retrieves nutrition data corresponding to the foods and drink purchased by the user. The server then calculates a revised nutrition value based on dividing a value of the nutrition data corresponding to the foods and drink purchased by the user by the person count number. The server generates and sends to the user device an image data that includes the revised nutrition value.
