Download How to Scan QR Codes on the iPhone with Scan App – QR codes are those weird looking pixelated boxes you see at some retailers, events, and even some ads. The idea behind them is that you scan the QR Code, to which you will then be provided information about whatever it is you?re scanning, whether that?s jumping to a website, seeing a message, getting a coupon, or some similar action. Some Android phones ship with a QR code reader installed from their provider as part of a suite of preinstalled applications, but iPhones never do, which means to scan a QR code on an iPhone you?ll have to visit the App Store first. We?ve tested a handful, and the best app for scanning QR Codes on the iPhone (or iPad or iPod touch, for that matter) is called Scan. Appropriately named, Scan is a small free download and it?s lightning fast to use.
