We have code in git that encodes arbitrary (but size-constrained) data as a redundant datamatrix barcode and shows it on the screen, and code that performs image analysis from a camera capture when one XO is pointed at another with such a barcode on the screen to decode the original data: <http://dev.laptop.org/git?p=projects/barcode;a=tree> The original purpose was to facilitate a physical public key exchange ("digital introduction") by holding two laptops up to one another. -- Ivan Krstić <[EMAIL PROTECTED]> | http://radian.org _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
