"Electronic Cash" by DigiCash is a new concept in payment systems. It combines computerized convenience with security and privacy that improve on paper cash. It adds value to any service involving payment. And it's versatility opens up a host of new markets and applications.

"Electronic Cash" is not just a step on the way to tomorrow's payment system technology. It is that technology, and it's here now. DigiCash works with payment system and service providers in all phases of electronic cash innovation. We help you develop and refine the concept, and we see it through every step to final implementation. We're the experts.

We're the experts first of all because our technology is unique - and we invented it. But we're also world-class experts in our fields. The DigiCash team brings together top cryptographers and payment-system specialists with some of Europe's best software and hardware specialists. DigiCash is young but experienced, innovative but here to stay. Wherever value is exchanged, between business, government, customer, client, or citizen, electronic cash is the medium of choice. For computerized payments over the phone, the user needs only our special software. Road toll payments can be made from moving vehicles - in less time than it takes a car going 200 km/h to travel a single meter. And users can pay directly at a counter, kiosk, or phone booth with current smart-cards as the platform; with the pocket-size card readers we’ve developed, they can even make payments to each other.
