Introduction
Parties Involved in a Card Transaction
- Cardholder:
This person uses a credit or debit card to pay for goods or services. They then offer the card to a merchant to pay for products or services.
- Merchant / Retailer:
The cardholder purchases goods or services from the shop or merchant.
- Card Issuer:
The financial organization (Rupay, Visa, Mastercard, Amex, etc.) that offers credit cards to the cardholders taking part in the transaction is known as the card issuer.
- Merchant’s Bank or the Acquiring Bank:
The acquiring bank is where the business, or merchant, has an account. When a customer pays for something, the money from the transaction is sent to this account once the payment is complete.
- Issuing Bank:
The issuing bank houses the customer’s bank account from which payments for goods/services will be deducted.
- Payment Gateway:
A payment gateway is the technology used at the PoS terminal where the customer and the shop interact. It reads the credit card information, encrypts it, and then sends it to the merchant’s bank through the payment processor.
- Payment Processor:
The payment processor is a company that helps share information between the card company (like Visa or Mastercard) and the banks to make sure the payment goes through.
Steps involved in Credit Card Processing
Payment Authorization
Here’s how it works
- When a customer swipes or taps their card at an Innoviti terminal, the card’s details are sent as secret (encrypted) data to the merchant’s bank (called the acquiring bank) through the payment gateway.
- The payment gateway then sends the data to the payment processor using the credit card’s network (like Visa or Mastercard).
- The payment processor talks to the customer’s bank (the issuing bank) to check if the cardholder is who they say they are and if there’s enough money in their account.
- If everything is fine, the customer’s bank approves the payment, and the PoS terminal shows the transaction is successful.
Payment Authentication
Here’s how it works:
- The payment gateway sends the “approved” message to the payment processor after the payment is approved.
- The payment processor uses the card network (like Visa or Mastercard) to inform the merchant’s bank (acquiring bank) that the payment is on its way.
- The payment processor deposits the money into the merchant’s account, keeping a small fee for its services.
- The customer’s bank (issuing bank) deducts the total amount (price + fees) from the customer’s account and sends it through the card network to the payment processor.
- The customer receives a receipt or invoice showing the details of the transaction.
Payment Settlement
What Else You Need to Know
Most card machines in stores can safely read special “chip cards” called EMV cards. Innoviti’s POS machines are fast and secure, making it simple for stores to take credit card payments.
The charge slip for the transaction will finally appear on both the retailer’s and the customer’s billing statement. Every day, the retailer sends a list of approved payments to their bank (the acquirer). The credit card firm receives the transactions, settles them, and sends the acceptable transactions back to the issuer.
