Electronic
payment systems
SET is a standard for
electronic payment systems around which proprietary payment systems can develop
applications.
Other payment systems in use
include CyberCash, Ecash, PayPal.
Consumers will not wish to
have to conform to several different payment system requirements, e.g.. a
CyberCash wallet, Surelink registration, or Ecash purchases and so on. Wallet
technology, which will probably be supplied with browsers, will need to provide
seamless support for the main payment systems.
