I Was Today Years Old When I Learned You Can Scan Documents on an iPhone Using the Notes App

Open the Notes app, which looks like a sheet of lined paper, by accessing it from your home screen.

Once you've clicked the Notes app icon and you have a new notes file open, locate and tap the "+" icon that can be found on the bottom middle of your screen. If your keyboard is on, it will appear in a bar right above the keyboard.

Note: If you don't see it, go to Settings->iCloud->Notes and turn that on. Then, once you go back to Notes, the "+" should appear.

Once you click the "+" icon, a list of options should appear. Choose "Scan Documents."

Once you hit "Scan Documents," a camera screen will appear. Point your phone camera at your document. It should automatically locate the document and highlight it in yellow (this can sometimes take a few tries at first — don't worry!). Once the document you want to scan is highlighted completely in yellow, it will automatically capture the document image or you can also tap the bottom white icon to do this. In my case, my document was easily detected and automatically scanned and saved.

The document will then be saved to that Note file, which can be easily accessed and sent as a message, email, or more. It's that simple!
