How to use Apple’s terrific document scanner in iOS 11 - The Verge | iPads, MakerEd and More  in Education | Scoop.it

If there’s a business card, receipt, or any other document you want to save or mark up, this tool makes getting it on your iPhone or iPad dead simple. If you’ve been using a third-party app for this purpose until now — and there are several great ones — you can probably uninstall it in favor of Apple’s own solution. That’s what I did, anyway.
