QR Codes! What the heck is a QR Codes?
I know that is what some of you are thinking right now. Well here is the Wikipedia answer to that: QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional bar code).
The QR code was invented in Japan by the Toyota subsidiary Denso Wave in 1994 to track vehicles during manufacture. It was designed to allow high-speed component scanning. It has since become one of the most popular types of two-dimensional barcodes and has completely invaded the web and mobile devices.
