Problems solved by technology

[0002] Shopping cards or point cards are used in many real-life scenarios, such as supermarkets, bakeries, etc., but traditional shopping cards have natural disadvantages. Physical shopping cards need to write the balance into chips (NFC, etc.), and then make them into physical cards. High production cost and cumbersome process
In addition, most of the shopping cards are anonymous. Once lost, they cannot be reissued, causing economic losses to the cardholders. Moreover, only the company can see the detailed records of the shopping card consumption records, and the flow of funds is opaque.

Abstract

The invention discloses a shopping card implementation method based on a block chain. The invention relates to the technical field of block chain shopping cards. According to the technical scheme, thetechnical problems that an entity shopping card is high in manufacturing cost and unclear in fund flow direction are solved, the key point of the technical scheme is that the physical identity and the digital identity of an enterprise are mapped and written into a block chain through an intelligent contract, the block chain shopping card similar to non-homogenized tokens is issued, and the blockchain shopping card can be additionally issued and can also be used for self-transaction. According to the block chain shopping card, the cost is saved, and an entity card does not need to be manufactured; the shopping card is easy to manage and use and not easy to lose, a cardholder uses the digital wallet to manage the shopping card, a two-dimensional code is generated during use, and the shopping card cannot be lost forever as long as the cardholder backs up his own wallet private key safely.

Description

technical field [0001] The present disclosure relates to the technical field of blockchain shopping cards, in particular to a blockchain-based shopping card implementation method. Background technique [0002] Shopping cards or point cards are used in many scenarios in real life, such as supermarkets, bakeries, etc., but traditional shopping cards have natural disadvantages. Physical shopping cards need to write the balance into chips (NFC, etc.), and then make them into physical cards. The production cost is high and the process is cumbersome. In addition, most of the shopping cards are anonymous. Once lost, they cannot be reissued, causing economic losses to the cardholders. Moreover, only the company can see the detailed records of shopping card consumption records, and the flow of funds is opaque. Contents of the invention [0003] The present disclosure provides a method for realizing a shopping card based on blockchain, and its technical purpose is to provide a bloc...
