QR Code

Seen those funky little QR (quick response) bar codes floating around and wondering how to scan them on your iPhone or iPad? QR codes are used to store useful information like web URLs, contact cards, e-mail addresses, etc… While QR reading isn’t built into a pre-installed iOS App, there are, of course, third-party apps for that.
