1. A method for transferring a set of data using a color image, the method comprising the steps of:
dividing the set of data into a group of two or more data chunks; assembling a color barcode image encoded with the set of data, wherein the color barcode represents a superposition of black-and-white two dimensional (2D) -barcode images, one black-and-white 2D-barcode image for each of said data chunks; displaying the color barcode image on a color display of a sending device; capturing a color image of the displayed color barcode image with a camera of a receiving device; filtering the captured color image to obtain a series of black-and-white images; processing each of the obtained series of black-and-white images to extract corresponding black-and-white 2D-barcodes; decoding each of the extracted black-and-white 2D-barcodes to obtain corresponding decoded data chunks; and combining the obtained decoded data chunks into a received set of data.
