A credit card is a payment card issued by a financial institution, such as a bank, that allows the cardholder to borrow funds up to a certain limit in order to make purchases or withdraw cash. When the cardholder makes a purchase, the amount is deducted from their available credit limit. The cardholder is then required to make a minimum monthly payment, which is typically a percentage of the total balance, along with any interest and fees. If the cardholder does not pay the balance in full by the due date, interest is charged on the remaining balance.
When a credit card is used to make a purchase, the transaction information is sent to the card issuer (the bank or financial institution that issued the credit card) for authorization. This information includes the cardholder’s account number, the merchant’s identification number, and the purchase amount.
The card issuer then checks to see if the cardholder’s account is in good standing and if the requested purchase amount is within the cardholder’s credit limit. If the account is in good standing and the credit limit has not been exceeded, the card issuer sends an approval code to the merchant, allowing the transaction to be completed.
The approval code is sent via the payment network (such as Visa or Mastercard) to the merchant’s acquiring bank, which then sends the request to the card issuer for final approval. Once the card issuer approves the transaction, the acquiring bank sends a message to the merchant to proceed with the sale. The merchant will then charge the amount of the purchase to the cardholder’s account.
The technical process behind this is known as Electronic Funds Transfer (EFT) and it works through a secure network that connects the merchants and the card issuers. The process uses advanced encryption and authentication protocols to ensure the security of the transaction.
