A business card having a QRC image, and method and system for transferring business card information from a QRC to a mobile communication device is disclosed herein. This matrix of cross-hybridization potentials may be determined experimentally by repeating a microarray experiment with each of the targeted genes individually present to determine the cross-hybridization of that targeted gene to each probe, or alternatively, computational models of hybridization may be employed. Two sets of links are used and the two sets are associated via spur gear engagement.
