CREDIT CARD FRAUD A major problem for E-commerce
The merchant has no legal proof of purchase unless the buyer uses authentication certificate

Nochargeback.com has lists of fraudlent cards, e-mail addresses and postal addresses
VeriSign/CyberCash has employed AI to catch frauders

DIGITAL CURRENCY

Buyers deposit cash in the account and spend it at
E-Commerce sites (acct # is passed using secure
proprietary protocol)

is limited to account balance

partnership with member E-Commerce sites

PayPal.com – digital payment system Acts as a trusted third party (e.g. auction purchase)
To send money: Sender sets up an account and requests to send payment
Sender places payment into the receivers account by credit-card
Reciever is notified of payment via email
Receiver can transfer funds to bank account or request a cheque

SMART CARDS
Cards with computer chips embedded on their faces – very common in Europe
Used for health care, transportation, ID, retail, pay phones, loyalty programs, banking machines
Smart card readers interface with card and request user PIN for access
Bank machines can load cards with cash and then merchants can download cash from card

MICRO-PAYMENTS
Long distance phone call charge is an example of a
micro-payment
Digital Equipment Corporatiion (DEC) researchers
originally envisioned MPs:
Payment per newspaper article ($0.005)
Payment by stock quote ($0.001)
Payment per click (Qpass, Inc)
Has not been popular, instead advertisers pay for
info, or customers pay flat rates … Why?
18
WHY HAVE MICRO-PAYMENTS FAILED?
Overly complicated for customer and
business – technology & accounting
Income is very dependent on customer use
(difficulties in cashflow management)
Customer anxiety – could act as a deterent
Difficulties in standardization – lost of
different approaches, variant media
