  2. Agenda • Concept • First and Current Implementations • Smart Card Based Systems - Open System - Close System • Alternative Systems • Software Based Systems • Evolution, future approaches • General Issues • Conclusions

  3. Concept • Money exchanged eletronically involving microprocessors computer networks, internet and digital stored values. • Two General Forms • Card Based • Software Based

  4. First and Current Implementations • Smart Cards Generally defined as a portable data storage device with intelligence (chip memory) and provisions for identity and security.
