Mondex is a smart card electronic cash system which was originally developed by National Westminster Bank in the United Kingdom and subsequently sold to MasterCard International. Mondex launched in a number of markets during the 1990s, expanding from an original trial in Swindon, UK to Hong Kong, Guelph, and New York. It was also trialled on several British university campuses from the late 1990s, including the University of Edinburgh, University of Exeter (between 1997 and 2001), University of York, University of Nottingham, Aston University and Sheffield Hallam University.
The Z notation was used to prove security properties about Mondex, allowing it to achieve ITSEC level E6, ITSEC's highest granted security-level classification.
