This is a project to automate invoice reading.
There is a government program ("Sua Nota tem Valor") created to make everyone aware of the importance of demanding invoices or receipts, as well as to encourage participation in social control and the application of public resources. More information about program here.
To join the program you have to input your invoices into an app. The way you can do it is using a scan feature availabe in app.
Quite often the scan feature is not able to recognize the number of invoice and I have to input it manually what takes more time and effort. This situation discourages my participation in the program.I also identify that other people has this issue in app reviews:
Create a solution using python to automate invoice reading making possible to input its number in the app
