Credit Card
Payment using credit card is one of most common

mode of electronic payment.
Credit card is small plastic card with a unique number

attached with an account.
It has also a magnetic strip embedded in it which is

used to read credit card via card readers.
When a customer purchases a product via credit
card, credit card issuer bank pays on behalf of the
customer and customer has a certain time period after
which he/she can pay the credit card bill.
It is usually credit card monthly payment cycle.
 Following are the actors in the credit card system.

The card holder - Customer
The merchant - seller of product who can
accept credit card payments.
The card issuer bank - card holder's bank
The acquirer bank - the merchant's bank

mastercard.

Debit Card
Debit card, like credit card is a small plastic card with a
unique number mapped with the bank account number.
It is required to have a bank account before getting a debit
card from the bank.
 The major difference between debit card and credit card
is that in case of payment through debit card, amount gets
deducted from card's bank account immediately and
there should be sufficient balance in bank account for the
transaction to get completed.
Whereas in case of credit card there is no such compulsion.
Debit cards free customer to carry cash, cheques and even
merchants accepts debit card more readily.
Having restriction on amount being in bank account also

helps customer to keep a check on his/her spending.
Smart Card
Smart card is again similar to credit card and debit card in
apperance but it has a small microprocessor chip embedded
in it.
It has the capacity to store customer work related/personal

information.

per usage.

encrypted format and are less expensive/provides faster
processing.

cards.
E-Money
E-Money transactions refers to situation where payment is
done over the network and amount gets transferred from one
financial body to another financial body without any
involvement of a middleman.
E-money transactions are faster, convenient and saves a lot

of time.
Online payments done via credit card, debit card or smart
card are examples of e-money transactions.
Another popular example is e-cash. In case of e-cash, both

customer and merchant both have to sign up with the bank
or company issuing e-cash.
E-Cash (Electronic-cash) Internet Payment
Online payments via debit cards, credit cards or smart

card are the examples of e-money transactions.
E Cash is transferred directly from customer’s desktop

to the merchant’s site.

operation between several banks,
government entities, technology
companies and e-commerce
organizations.

large organizations

BENEFITS TO SELLERS
Online payment risk assessment
Charge-backs – the risk of refunds on our merchant
account;
Forecast turnover figures – higher turnover can generate

higher exposure;
Average transaction size – if we sell very high value items

(diamonds, cars) this will influence the risk analysis of our
business;
Time from payment to order fulfillment – The longer it

takes to dispatch goods to a customer, the greater the risk of
an order cancellation;
Length of trading record – a start-up company presents

more risk than a well established business;
Risks in Electronic Payment systems:
 Customer's risks
Stolen credentials or password – Dishonest
merchant – Disputes over transaction – Inappropriate
use of transaction details
