Byte Card and UK trials

The forerunner of Mondex E-Purse was the BYTE Card. Byte card was the pilot conducted at the Goodmans Fields Data centre of NATWEST bank. We will try to show the general time order of these cards and the Mondex early trials.
Special thanks go to the systems inventor David Everett (Patents holder), Chris Potts, Nick Walling, and Bill Reding, as well as fellow collector David Strømstad.

We have also had donated to the Card Museum, the important collection of Ian Simmons (RIP), who also held patents for Mondex development. See our section under Industry supporters for his BIO:
