Intelligent Form Filling System of Original Invoice Voucher Based on WeChat Applet

In the process of personal financial reimbursement, for the problem that the original invoice vouchers cannot be retained and the reimbursement information cannot be managed, a system for personal original invoice stub management and automatic entry of financial reimbursement information is designed and implemented. The front end uses a WeChat applet, and the basic information of the invoice is extracted by scanning the QR code of the invoice picture. The back end uses a lightweight framework based on Python Flask combined with vue.js to process business logic and the original voucher picture and information storage of the invoice, which realizes the separation of the front end and back end.
