A data carrier, such as a security card or bank card is disclosed having a stripe of machine readable markers formed on it. The markers (10, 12, 16, 18) are different colours, and more precisely, different spectra. By passing light through the markers and detecting the spectrum of a marker, information represented by different spectra can be decoded.
