Description

Digital receipt issuing system and method{SYSTEM AND METHOD FOR ISSUING DIGITAL RECEIPT}

The present invention relates to a system for issuing a digital receipt, and in particular, an extension that enables the issuance, storage and management of a digital receipt including a payment amount through text or e-mail, not in a form printed on paper when purchasing a product. It relates to a digital receipt issuing system and method that provides the service.

In general, when there is a transaction relationship between goods, services, and assets in daily life, paper receipts or confirmations are exchanged and used as evidence of transaction behavior with each other.

However, since most receipts are issued in the form of a printed paper, there is a risk of loss, and in the case of individuals, most of them are discarded even if the receipt is issued after payment.

In addition, since current receipts are provided in various sizes and shapes depending on the issuer, it is difficult for consumers to systematically check and manage consumption details.

In particular, as a result of analyzing the status of credit and debit card payments through 13 VAN (payment agency) companies, it was found that paper receipts issued in 2018 amounted to 1.48.89 billion and the issuance cost of about 11.9 billion won. Including large-scale affiliated stores such as department stores that exchange payment and approval details directly with card companies without going through VAN, it is estimated that approximately 103.1 billion KRW is incurred annually for issuing paper receipts, and greenhouse gas emissions and garbage emissions are 2 respectively. It can be seen that there are 2,893 tons and 9358 tons, which incur considerable social costs due to the issuance of paper receipts.

In order to improve this problem, various types of digital receipts have recently been proposed that can replace paper receipts using mobile terminals such as mobile phones or smart phones possessed by most people.

According to the known digital receipt service method, the issuing server receives payment information from the POS device through the Internet network, and extracts the identification code of the customer terminal installed with a dedicated application to identify the transaction party and the customer terminal, and the transaction details are included. The generated digital receipt is generated and sent to a dedicated application in the form of a push message.

However, according to the known digital receipt service method, there is a disadvantage in that the service is possible only when a dedicated application capable of receiving and displaying digital receipts is previously installed on all customer terminals.

In addition, the known digital receipt service method provides only a function of simply receiving and storing an issued digital receipt, and there is a limitation in that it cannot provide any useful function using a digital receipt.
