1. Overall System
CyberCash, Inc. of Reston, Virginia was founded in August of 1994 to
partner with financial institutions and providers of goods and
services to deliver a safe, convenient and inexpensive system for
making payments on the Internet. The CyberCash approach is based on
establishing a trusted link between the new world of cyberspace and
the traditional banking world. CyberCash serves as a conduit through
which payments can be transported quickly, easily and safely between
buyers, sellers and their banks. Significantly - much as it is the
real world of commerce - the buyer and seller need not have any prior
existing relationship.
As a neutral third party whose sole concern is ensuring the delivery
of payments from one party to another, CyberCash is the linchpin in
delivering spontaneous consumer electronic commerce on the Internet.
1.1 System Overview
The CyberCash system will provide several separate payment services
on the Internet including credit card and electronic cash. To gain
access to CyberCash services, consumers need only a personal computer
with a network connection. Similarly, merchants and banks need make
only minimal changes to their current operating procedures in order
to process CyberCash transactions, enabling them to more quickly
integrate safe on-line payments into their existing service
offerings. Communications with banks are over existing financial
communications networks.
