Concept
Money exchanged eletronically involving microprocessors
computer networks, internet and digital stored values.
Two General FormsCard BasedSoftware Based
First and Current Implementations
Smart Cards
Generally defined as a portable data storage device with intelligence (chip memory) and provisions for identity and security.
First and Current Implementations
Some History… 1970 - First implementation of microelectronic devices
in plastic substrate (Kunitaka Arimura) 1974 - First patent “An independent electronic object
with memory” (Roland Moreno). 1979 – First smart card by Honeywell Bull 1980’s First Trials in France
French Bank Card Association (Blue Card, Green Card, TA) University Cards in France
Date Information took from The Changing Face of Money, Good Barbara

First and Current Implementations
Smart Cards (Closed System)
A stored-value card that only can be used for one purpose or only in one determined environment.
First and Current Implementations
Octopus Card
Singapore (Public Transportation payment)
Chipknip
Octopus Card
Rechargeable without contact stored value smart card (mass transit system in Hong Kong)
Nowadays convenience stores, supermarkets, parking meters, vending machines, etc.
Off-line Electronic Money
The merchant does not need to interact with the bank before accepting a user’s coin.
Merchant guaranteed that the user’s e-coin will be accepted by the bank (the bank is able to identify cheating user).
Off-line Electronic Money
Blind Signatures to achieve unlikability between withdrawal and spend transactions.
Using cryptographyAnonymous e-cash was Introduced by David Chaum
Alternative Systems: Software Based Systems
Main Topic: Internet
Several Schemes devised to make purchases secure over the Internet
Security: Main concern for the method developers
Open Network MasterCard and Visa agreement
for SET (Secure Electronic Transactions) standard (1996)
Alternative Systems: Software Based Systems
Digital Gold Currency
Paypal
Liberty Reserve
Evolution, future approaches
Objectives
Turn it able to use it through wider range of hardware such as secured credit cards
Linked bank accounts for exchange with a secure micropayment system (Paypal)
In General…
Advantages:
Convenience Privacy Increased efficency of transactions Lower transaction fees New business opportunities
In General…
Disadvantages
How to levy taxesPossible facility of money launderingExchange rate instabilitiesShortage of money supplies
