5 QR Code Readers for iPhone

QR codes are popping up everywhere in the U.S. In case you aren’t familiar with the tech, a QR code is a type of barcode which is square and is made up of a complicated pattern of black and white dots. You can find them in magazines, on business cards, and even on billboards. When read with a camera and the right software, the code magically becomes a phone number, a URL, contact information and more.
