Do you have experience in developing a mobile application for scanning documents?

Question

Mobile development

Now there are many mobile applications with which you can take a picture of a document and it will be like a scanned one.

The coolest thing for my taste is Scannable from Evernote.

I want to build a similar solution into my mobile application, but not to reinvent the wheel, but to take a ready-made SDK for scanning documents using the phone's camera.

Has anyone dealt with a similar task?
What SDKs did you use?
Are there any free solutions for this task?

I googled solutions like this:
