iPad as Scanner

The Notes app which is native to your iPad has built in scanning abilities. All you need to do is create a new note and then use the + sign at the bottom right to choose Scan Documents. You can then use the Share icon at the top right to send that Note with the scanned images through an email, to Google Drive, or other connected applications or services. The link below provides more detailed instructions and screenshots for the process:
