allowing it to achieve ITSEC level E6, ITSEC's highest granted security-level classification. Card types In many countries the electronic purse was issued on a dual-application card, implementing two or more uses within a single card. In some instances, the Mondex card was issued alongside a regular credit card, allowing transactions to be made either with money stored in the Mondex wallet or via the traditional credit card. Other dual application uses included a user card in a private health service - holding personal health records and other details in cases of emergency; and a club membership card, containing special discounts and benefits.

It was operated entirely through a computer, and enabled a similar feature set to the electronic wallet when using its companion software.
