> Mondex was a smart card electronic cash system, implemented as a stored-value card and owned by Mastercard.
> Mondex allowed users to use its electronic card as they would with cash, enabling peer-to-peer offline transfers between cards, which did not need any authorization, via Mondex ATMs, computer card readers, personal 'wallets' and specialized telephones. This offline nature of the system and other unique features made Mondex stand out from leading competitors at the time, such as Visa Cash, which was a closed system and was much closer in concept to a traditional payment cards' transactional operation.
