electronic payment systems
Electronic Payment Systems

Electronic Payment Systems
  • Estimates of the cost of billing one person vary between $1 and $1.50.
  • Sending bills and receiving payments over the Internet promises to drop the transaction cost to an average of 50 cents per bill.
  • Today, four basic ways to pay for purchases dominate business-to-consumer commerce.
electronic payment systems6
Electronic Payment Systems
  • Electronic cash distribution and payment can be handled by wallets, smart cards, or proprietary, limited-use scrip.
  • Scrip is digital cash minted by a company instead of by a government.
  • Companies like Payment Online sell packages of payment processing services to Web merchants that accept several types of payments.
payment cards
Payment Cards
  • Payment cards are all types of plastic cards that consumers use to make purchases:
    • Credit cards
      • such as a Visa or a MasterCard, has a preset spending limit based on the user’s credit limit.
    • Debit cards
      • removes the amount of the charge from the cardholder’s account and transfers it to the seller’s bank.
    • Charge cards
      • such as one from American Express, carries no preset spending limit.
advantages and disadvantages of payment cards
Advantages and Disadvantages of Payment Cards
  • Advantages:
    • Payment cards provide fraud protection.
    • They have worldwide acceptance.
    • They are good for online transactions.
  • Disadvantages:
    • Payment card service companies charge merchants per-transaction fees and monthly processing fees.

Payment Acceptance and Processing
  • Open and closed loop systems will accept and process payment cards.
  • A merchant bank or acquiring bank is a bank that does business with merchants who want to accept payment cards.
  • Software packaged with your electronic commerce software can handle payment card processing automatically.
electronic cash
Electronic Cash
  • Electronic cash is a general term that describes the attempts of several companies to create a value storage and exchange system that operates online in much the same way that government-issued currency operates in the physical world.
  • Concerns about electronic payment methods include:
    • Privacy
    • Security
    • Independence
    • Portability
    • Convenience
electronic cash issues
Electronic Cash Issues
  • Primary advantage is with purchase of items less than £5
      • Credit card transaction fees make small purchases unprofitable
      • Facilitates Micropayments – eg for items costing less than £1
  • Must be anonymous, just like regular currency
  • Safeguards must be in place to prevent counterfeiting
  • Must be independent and freely transferable regardless of nationality or storage mechanism
electronic cash storage
Electronic Cash Storage
  • Two methods
    • On-line
      • Individual does not have possession personally of electronic cash
      • Trusted third party, e.g. e-banking, bank holds customers’ cash accounts
    • Off-line
      • Customer holds cash on smart card or electronic wallet
      • Fraud and double spending require tamper-proof encryption
electronic cash16
Electronic Cash

Advantages

  • Electronic cash transactions are more efficient and less costly than other methods.
  • The distance that an electronic transaction must travel does not affect cost.
  • The fixed cost of hardware to handle electronic cash is nearly zero.
  • Electronic cash does not require that one party have any special authorization.

Disadvantages

  • Electronic cash provides no audit trail.
  • Because true electronic cash is not traceable, money laundering is a problem.
  • Electronic cash is susceptible to forgery.
  • So far, electronic cash is a commercial flop.
how electronic cash works
How Electronic Cash Works
  • Customer opens account with bank in person and establishes identity
    • Thereafter, digital certificate serves as proof of identity
  • Once identified, bank issues e-currency and deducts amount from customer’s account (minus service fee)
  • Customer spends e-cash with merchant who validates it to prevent forgery or fraud
  • Merchant presents e-cash to issuing bank for deposit once goods or services are received
providing security for electronic cash
Providing Security for Electronic Cash
  • To prevent double spending, the main security feature is the threat of prosecution.
  • A complicated two-part lock provides anonymous security that also signals when someone is attempting to double spend cash.
  • One way to trace electronic cash is to attach a serial number to each electronic cash transaction.
electronic cash systems
Electronic Cash Systems
  • Compaq Computer’s electronic cash technology allows users to use its NetCoin electronic cash.
  • KCOM offers its own NetCoin electronic cash system and offers electronic cash through its NetCoin Center.

  • After their card is activated, customers can pay for purchases using the InternetCash card at any site that accepts it.

  • The consortium of America Online, Compaq, Dell, IBM, Microsoft, Visa USA, and MasterCard has agreed on a technology called ECML, or electronic commerce modeling language.
  • The ECML standard will expedite online processing for customers by simplifying the form-filling procedure.
stored value cards
Stored-Value Cards
  • A stored-value card can be an elaborate smart card or a simple plastic card with a magnetic strip that records the currency balance.
  • A smart card is better suited for Internet payment transactions because it has limited processing capability.
smart cards
Smart Cards
  • Plastic card containing an embedded microchip
    • Can contain cash
    • Over 100 times more information storage than a magnetic-striped plastic card
    • Information is encrypted, unlike credit cards which have account number on its face, making credit theft practically impossible
smart cards36
Smart Cards

  • 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.; success depends on:
    • Critical mass of smart cards that support applications
    • Compatibility between smart cards, card-reader devices, and applications

m obile payments the future
M(obile)-Payments – the future?

“Analysts believe that easy mobile payment is one of the main prerequisites for the success of m-commerce. When the mobile phone can function as an electronic wallet for mobile payments, including micropayments, application developers will find it attractive to introduce new mobile communication services to the market. Examples include mobile entertainment (downloads of music, mobile gambling, etc.), information services (sports news, horoscopes, location-based services, etc.), and real-world services (paying parking fees, buying train or concert tickets, etc.). Network operators envision micropayments as an attractive business that does not compete with banks or credit card companies. For the end user, PayCircle will make m-commerce easy and secure and thus eliminate the major hurdles to widespread adoption and popularity.”
