A debit card is a plastic card that provides a cardholder electronic access to his / her bank account. It can be used to withdraw funds or to make purchases using money in the bank account. Since a debit card is essentially linked to a checking account (saving / current), it is also known as a Checking Card. A balance in the checking account is must for the use of debit card.

A credit card is a payment card which allows the cardholder to pay for goods and services on the basis of line of credit granted to him / her by the issuing bank.  A credit card essentially creates a revolving account from which cardholder can borrow money for payment to merchant (and also withdraw cash). A credit card is not linked to a bank account but is linked to the bank / financial institution which has issued it.

Differences between Debit Card and Credit Card

How the Credit Card transaction works?

The process can be divided into two parts viz. authorization and Clearing & Settlement.

Authorization

A credit card holder finalizes the goods to be bought and presents his card to the merchant. Merchant processes the card and while processing it seeks authorization from the Merchant Bank giving it information on transaction information. Merchant Bank submits the authorization request to Credit Card Network  (MasterCard or VISA). Credit Card Network sends the request to the Card Issuer which is ICICI bank. Card Issuer either approves or declines the transaction. If it authorizes, the Credit Card Network forwards this authorization to merchant bank. Merchant bank forwards this response to the Merchant and Merchant once receiving this authorization completes the transaction.

Clearing and Settlement

The merchant deposits the transaction receipt with the merchant bank, which credits the Merchant’s account and submits this transaction to Credit Card Network for settlement. Credit card Network pays the Merchant Bank and debits the account of Card Issuer. The Card Issuer posts the transaction to the account of Card holder. The cardholder received monthly statement from the Issuer. The Cardholder pays as per the conditions.
