INTACTA.CODE

INTACTA CODE is a bar code symbology designed to store a large amount of data, with built-in compression, encryption, and error correction. It also has a randomization system, so that apparently no two INTACTA codes for the same data are identical, which is supposed to provide security or authentication or something of the sort.
