This can be done with the scan button on the document page in the app. External factors may influence the scan performance; such as light and light reflections, quality of the transfer form, type of device... It is best to keep these things in mind. The better the circumstances, the better the result. Furthermore, you should focus on the part of the transfer where the readable date (amount, recipient data, statement) are noted. When the scan corners turn green on the screen, you know that your device is positioned correctly. Scanning is very easy, certainly once you've got the hang of it.
