Credit card processing is not a new concept. Everyone claims to know the process: swipe the card, hit the button and the transaction is complete in a blink. But do you really know the process? Do you think that it is as simple as it seems? It actually is a much more complex procedure than what you witness. The fact is swiping the card and signing the recipe is the first and the last step of the procedure. In between lays multiple steps that include more than one person working invisibly for the customer to complete that particular transaction.
Let us understand transaction process in just three steps
STEP 1: AUTHENTICITY
At the point of sale, a cardholder gives the card to the merchant to swipe the card on POS terminal to make a payment.
Credit card details are sent to the acquiring bank, which forwards the same to the credit card network
Authorization request includes credit card number used for the payment, expiration date, billing address, card security code and the payment amount.
Credit card network clears the payment and a request is sent to the issuing bank for an authorization.
STEP 2: AUTHENTICATION
When the issuing bank receives the authorization request, it validates the credit card number, checks the availability of the funds in the cardholder’s account, verifies the billing address and validates Card security code (CVV number).
It is up to the issuing bank whether to approve or deny the request. When they make a decision, it sends back the suitable response through a proper channel (credit card network and acquiring bank).
Once the merchant receives the authorization, the customer is provided with the receipt at the completion of the sale.
STEP 3: CLEARING AND SETTLEMENT
In clearing stage, the transactions get the post to the cardholder’s monthly billing statement and in the merchant’s statement.
For settlement, service provider routes the batched information to the association member, which in turn forwards all the approved transactions to the corresponding issuing bank.
The merchant sends all the approved authorizations in a batch to the acquiring bank by EOD.
The merchant account gets credited for the cardholder’s purchases by the acquiring bank (minus merchant discount rate). At this time, the issuing bank posts the transaction information to the cardholder’s account. The cardholder receives the statement and bill is paid off.
Then the issuing bank transfers the funds (minus interchange fee, which is shared with the credit card network) within 1-2 days. Then the credit card network pays from the remaining funds to acquiring bank as well as the acquiring processor.
