Types of Payment Systems Cash Checking Transfer Credit Card Stored Value Accumulating Balance
Types of Money? Method Anonymous Trail Credit/debit Peer to Peer Cash Credit Card Check/Debit
E-Payments
Types of Money? (2) Method Immediate/delay Gross/net Fees: Fixed or fraction Cash Credit Card Net Fraction Check/Debit Gross Fixed In the physical world, check payments far outnumber credit card transactions. Not so on the internet. Think, too, about finality, revocability, convenience, vulnerability, timing (contemporaneous, before or after), independence of location, divisibility and recombination
Cash Legal tender defined by a national authority to represent value Most common form of payment in terms of number of transactions Instantly convertible into other forms of value without intermediation of any kind Portable, requires no authentication, and provides instant purchasing power Free (no transaction fee), anonymous, low cognitive demands Limitations: easily stolen, limited to smaller transaction, does not provide any float
Checking Transfer Funds transferred directly via a signed draft or check from a consumer s checking account to a merchant or other individual Most common form of payment in terms of amount spend Can be used for both small and large transactions Some float Not anonymous, require third-party intervention (banks) Introduce security risks for merchants (forgeries, stopped payments), so authentication is typically required; Ensured checks (e.g. money orders) do not have this problem
Credit Card Represents an account that extends credit to consumers allows consumers to purchase items while deferring payment Credit card associations Nonprofit associations (Visa, MasterCard) that set standards for issuing banks Issuing banks Issue cards and process transactions Processing centers (clearinghouses) Handle verification of accounts and balances
Credit Card Players on the Net Cardholder Consumer or corporate purchaser using credit cards Merchant Entity that accepts credit cards and offers goods or services in exchange of payments Card Issuer Financial institution that establishes accounts for cardholders and issue credit cards Acquirer Financial institution that establishes an account for merchants and acquires the vouchers of authorized sales slips Card Brand Association of issuers and acquirers created to protect and advertise the card, enforces rules, and provide networking for institutions
Stored Value Accounts created by depositing funds into an account and from which funds are paid out or withdrawn as needed Examples: Debit cards, gift certificates, prepaid cards, smart cards Debit cards: Immediately debit a checking or other demand-deposit account.
Accumulating Balance Accounts that accumulate expenditures and to which consumers make period payments Examples: utility, phone, American Express accounts

Current Online Payment Systems Credit cards are dominant form of online payment, accounting for around 85% of online payments in 2006 (BUT B2B!) New forms of electronic payment include: Digital cash Online stored value systems Digital accumulating balance payment systems Digital credit accounts Digital checking
Various Payment Methods Offered or Planned to be Offered by Online Merchants SOURCE: Based on data from Cybersource Corporation, 2005.
Online Credit Card Transactions Processed in much the same way that instore purchases are Major difference is that online merchants do not see or take impression of card, and no signature is available (CNP transactions) Participants include consumer, merchant, clearinghouse, merchant bank (acquiring bank) and consumer s card issuing bank
Online Credit Transactions (cont.) 29
Limitations of Online Credit Card Payment Systems Security merchant and/or consumer may not be fully authenticated ( and usually are not). Cost for merchants, around 3.5% of purchase price plus transaction fee of 20-30 cents per transaction Many people do not have access to credit cards (young adults, say)
The SET (Secure Electronic Transaction) Protocol Authenticates cardholder and merchant identity through use of digital certificates An open standard developed by MasterCard and Visa Transaction process similar to standard online credit card transaction, with more identity verification Thus far, has not caught on much, due to costs involved in integrating SET into existing systems, and lack of interest among consumers
SET Transactions (cont.) 32
Digital Wallets Concept of digital wallet relevant to many of the new digital payment systems Seeks to emulate the functionality of traditional wallet Most important functions: Authenticate consumer through use of digital certificates or other encryption methods Store and transfer value Secure payment process from consumer to merchant Two major categories: Client-based digital wallets Gator.com, MasterCard Wallet Server-based digital wallets MSN Wallet
Digital Cash One of the first forms of alternative payment systems Not really cash rather, are forms of value storage and value exchange that have limited convertibility into other forms of value, and require intermediaries to convert Many of early examples have disappeared; concepts survive as part of P2P payment systems
Digicash: First Generation Digital Cash 35
PayPal: Second Generation of Digital Cash 36
PayPal (cont.) One of e-commerce s major success stories: Went public in 2002; acquired by ebay October 2002 for $1.5 billion An example of a peer-to-peer payment system Fills a niche that credit card companies avoided individuals and small merchants Piggybacks on existing credit card and checking payment systems Weakness: suffers from relatively high levels of fraud Competitors include Western Union (MoneyZap), AOL (AOLQuickcash) and Citibank (C2it)

Digital Payment Systems and the Wireless Web Mobile payment (m-payments) systems not very well established yet in U.S, but with growth in Wi-Fi and 3G cellular phone systems, this is beginning to change Example: Qpass, AT&T and Wayport venture to provide mobile payment and billing called GoPort Gartner predicts m-payments worldwide will total at least $30 billion by 2002; majority of transactions will be micro-m-payments
B2B Payment Systems More complex than B2C Two main types: Systems that replace traditional banks (example: Actrade) Existing banking systems extending to B2B marketplace (example: Orbian)
Electronic Billing Presentment and Payment (EBPP) Online payment systems for monthly bills EBPP expected to grow rapidly, to an estimated 40% of all households by 2007 Main business models in EBPP market include: Biller-direct Consolidator Above are supported by EBPP infrastructure providers
Growth of the EBPP Market SOURCE: Based on data from emarketer, Inc., 2004b; Forrester Research, 2005; authors estimates.

Traditional Content Providers Newspapers Magazines Directories Book publishers Newsletters Photo libraries Music publishers Clip-art New Age Content Providers Applet developers Search engines Rating services Serialized soaps Interactive games Software add-ons Shopping agents Buyer/Seller brokering Home Alone Content Providers e-zines Personal essays Subject indexes How-To Guides Cookbooks Annotated bookmark files Personalized filtering
Electronic Cash and Micropayments Smart Cards The concept of e-cash is used in the non-internet environment Plastic cards with magnetic stripes (old technology) Includes IC chips with programmable functions on them which makes cards smart One e-cash card for one application Recharge the card only at designated locations, such as bank office or a kiosk. Future: recharge at your PC e.g. Mondex & VisaCash
Micropayments Issues Adoption by Internet users? How can anyone make money on such small transactions? What about marginal cost of reproduction? Will different micropayment systems ever interoperate? Risk Management: What about fraud and control?
Managerial Issues Security solution providers can cultivate the opportunity of providing solutions for the secure electronic payment systems Electronic payment system solution providers can offer various types of electronic payment systems to electronic stores and banks Electronic stores should select an appropriate set of electronic payment systems Banks need to develop cyberbank services to be compatible with the various electronic payment system Credit card brand companies need to develop an EC standard like SET, and watch the acceptance by customers Smart card brand should develop a business model in cooperation with application sectors and banks Certificate authority needs to identify the types of certificate to 63
