[0002] With the rapid development of Jingdong and Taobao, online shopping has become the mainstream trend of shopping, but it has brought some problems, especially paper invoices, which will inevitably lead to a huge amount of paper for traditional paper invoices, in addition to maintenance of billing equipment , management personnel and invoice storage, lost and red letter invoice management and other costs, resulting in waste of environmental resources and social resources

Therefore, the existing problem is that the existing invoices are basically printed on paper, resulting in a waste of social and environmental resources. Users hope to provide electronic invoices to reduce resource waste and save costs.

Although there is also technology to provide electronic invoices in the market, electronic invoices refer to electronically stored payment vouchers issued and obtained by units and individuals in the process of purchasing and selling goods, providing or receiving labor services, and engaging in other business activities. But it is basically a picture similar to a paper invoice, which is easy to be tampered with by picture processing software, and has no anti-counterfeiting function at all.
