20. Conclusion
• Online credit card payment system
widely accepted and most popular method of
payment in retail market.
Among different online credit cards, virtual
credit card (VCC) is secure, protects the user’s
privacy and is not limited to use at a fixed
location.
@SACHIN KUMAR YADAV
21. Electronic cash systems
Smart card based electronic-cash systems
have some advantages over traditional
electronic cash systems like- anonymity,
transfer payment between individual parties
and low transaction handling fees.
@SACHIN KUMAR YADAV
22. Electronic check systems
Include relatively high fixed cost and cannot
protect user’s anonymity.
Not suitable for retail transactions by
consumers.
Useful for government and B2B operations.
@SACHIN KUMAR YADAV
23. Micro payment systems
Existing micro-payment system not
established by any of the international
financial organization
Alliances with banks, internet portals, ISPs,
telecommunications service operators,
content providers, and customer service
providers are essential for survival
Inconvenient for consumers to use for micro
transaction, as requires to switch another
payment system for larger transaction
@SACHIN KUMAR YADAV
24. Recommendations
• Future electronic payment system must work well
with personal computers, mobile phones, digital
TV, and personal digital assistance.
• To increase penetration and popularity alliances
with other industries such as telecommunications,
cable television etc will be synergetic.
• Electronic payment systems in one country must
provide currency exchange for electronic payment
systems in another country.
