Basics of Credit Card (3)
Although using a credit card is an easy job for us, it’s not easy to finish the transaction. Use a credit card involves a lot of parties. And usually, it takes several days to settle down the transaction until it finally appear on your account.
Parties involved
Cardholder: The owner of the card used to make a purchase; the consumer.
Card-issuing bank: The financial institution or other organization that issued the credit card to the cardholder. This bank bills the consumer for repayment and bears the risk that the card is used fraudulently. American Express and Discover were previously the only card-issuing banks for their respective brands, but as of 2007, this is no longer the case.
Merchant: The individual or business accepting credit card payments for products or services sold to the cardholder.
Acquiring bank: The financial institution accepting payment for the products or services on behalf of the merchant.
Independent sales organization: Resellers (to merchants) of the services of the acquiring bank.
Merchant account provider: This could refer to the acquiring bank or the independent sales organization, but in general is the organization that the merchant deals with.
Credit Card association: An association of card-issuing banks such as Visa, MasterCard, Discover, American Express, etc. that set transaction terms for merchants, card-issuing banks, and acquiring banks.
Transaction network: The system that implements the mechanics of the electronic transactions. May be operated by an independent company, and one company may operate multiple networks. Transaction processing networks include: Cardnet, Nabanco, Omaha, Paymentech, NDC Atlanta, Nova, Vital, Concord EFSnet, and VisaNet.
Affinity partner: Some institutions lend their name to an issuer to attract customers that have a strong relationship with that institution, and get paid a fee or a percentage of the balance for each card issued using their name. Examples of typical affinity partners are sports teams, universities and charities.
The flow of information and money between these parties — always through the card associations — is known as the interchange, and it consists of a few steps.
Transaction steps
Authorization: When the cardholder pays for the purchase, the merchant performs some risk assessment and may submit the transaction to the acquirer for authorization. The acquirer verifies with the issuer—almost instantly—that the card number and transaction amount are both valid, and informs the merchant on how to proceed. The issuer may provisionally debit the funds from the cardholder’s credit account at this stage.
Batching: After the transaction is authorized it is then stored in a batch, which the merchant sends to the acquiring bank later to receive payment (usually at the end of the day).
Clearing and settlement: The acquiring bank sends the transactions in the batch through the card association, which debits the card-issuing bank for the transaction amount, and credits the acquirer for the transaction amount minus the interchange fee.
Funding: The acquiring bank pays the merchant. The amount the merchant receives is equal to the transaction amount minus the discount rate charged by the acquiring bank to the merchant for the service.
The entire process, from authorization to funding, usually takes about 2-7 business days. However, many merchant card processors offer next-day deposits to customers subject to type of banking account.
In the event of a chargeback (when there’s an error in processing the transaction or the cardholder disputes the transaction), the issuer returns the transaction to the acquirer for resolution. The acquirer then forwards the chargeback to the merchant, who must either accept the chargeback or contest it.
Ok. Next time, let’s see how can a credit card issuer can make profits from this process.
