The one tool I use most often to scan documents, receipts, images, etc., is CamScanner. It is a wonderful app and after having started on it, I have forgotten where my regular flatbed scanner is.
CamScanner helps you scan, store, sync and collaborate on various contents across smartphones, tablets and computers. Use your phone camera to scan receipts, notes, invoices, whiteboard discussions, business cards, certificates, etc. Once scanned, you can crop and auto enhance the images to make the texts and graphics look clear and sharp. You can then share the images in a variety of ways.
The paid version also has a great OCR engine, which allows you to read / convert the images as text.
It also supports 3rd Party Cloud Storage Services, such as Box, Google Drive, Evernote, Dropbox, OneDrive.
Try it out – it could just be the solution for all your scanning needs.
