The world might be going high tech, but try telling that to Indian student Sainul Abideen, who has apparently demonstrated how to encode 256Gbyte of data on an A4 sheet of paper.
The article at TechWorld says that Abideen prints multi-coloured geometric patterns onto the paper, which can be read back by a suitable scanner.
Files such as text, images, sounds and video clips are encoded in "rainbow format" as coloured circles, triangles, squares and so on, and printed as dense graphics on paper at a density of 2.7GB per square inch.
Abideen, who has just finished his Masters degree in Kerala at the MES College of Engineering, Kuttipuram, has named the process “Rainbow Technology”. He imagines using small pieces of card to store data which can be read by a scanner included in a laptop or desktop PC.
It's like data cards and punched paper tape all over again.
