MMCC

MMCC (Mobile multi-coloured composite) is a 2-D bar code symbology intended for use with mobile devices, something like the QR code, but in color. It has a higher data capacity than most bar code systems, allowing for entire images or even videos to be stored. It was developed at Edith Cowan University in Western Australia. (Since the state of Western Australia is abbreviated WA, some web reports about this system mis-attribute it to the state of Washington, USA, which is also abbreviated WA.)
