Free wallet software that stores credit card and personal
information on users’ computer, not on a central server;
information is dragged into payment form from eWallet


Works with Netscape and Internet Explorer
Microsoft Wallets

W3C Proposed Standard for Electronic Wallets

World Wide Web Consortium (W3C) is attempting
to create an extensible and interoperable method
of embedding micropayment information on a
web page
 Extensible
systems allow improvement of the
system without eliminating previous work
W3C Proposed Standard for Electronic Wallets

Merchants to accept several payment options to insure
the widest possible Internet audience

Merchants must embed in their Web page payment
information specific to each payment system

This redundancy spurred W3C to develop common
standards for Web page markup for all payment
systems

Must move quickly to prevent current methods from
becoming entrenched
Digital Cash



Digital forms of value storage or value exchange that have
limited convertibility into other forms of value and require

So far not successful in U.S., but popular in Europe,
Australia, and Japan
Unsuccessful in U.S. partly because few card readers
available
Smart cards gradually reappearing in U.S.; their success
depends on:
 Critical
mass of smart cards that support applications
 Compatibility
between smart cards, card-reader
devices, and applications
Mondex Smart Card

Holds and dispenses electronic cash

Developed by MasterCard International


Requires specific card reader for the merchants

telephone
Mondex Smart Card
