What is payment processing?
Payment processing is an online mechanism that enables financial transactions between customers and businesses. When a customer makes a purchase, a series of steps occur to verify, authorise, and transfer funds. Payment processing involves multiple entities, including the merchant, acquiring bank, issuing bank, and secure payment gateways.
In other words, payment processors facilitate the smooth transfer of funds by ensuring digital transactions are authenticated and approved. Online transactions would be inefficient and vulnerable to fraud without secure payment gateways and processing systems.
Steps involved in payment processing
The account payment process involves multiple steps to ensure smooth transactions. Below is a breakdown of these steps:
Initiation: A customer enters their payment details on the checkout page.
Authorisation: The payment gateway encrypts and sends the details to the acquiring bank.
Verification: The issuing bank verifies whether the customer has sufficient funds and approves or declines the transaction.
Processing: If approved, the acquiring bank requests funds from the issuing bank.
Settlement: The funds are transferred to the merchant’s account, and the transaction is settled.
Each step ensures that the online transaction process is smooth and secure for buyers and sellers.
Payment processing methods
Businesses use various payment processing methods to facilitate online transactions. These include:
Credit and Debit Cards
These are the most widely used methods, where transactions are processed through secure payment gateways. While Debit Cards allow users to spend money directly from their bank accounts, Credit Cards provide short-term loans for purchases.

Customers can also link their bank accounts and make payments through digital wallets. Common digital wallet services in India include PayZapp, Google Pay, PhonePe, Paytm, and Mobikwik.
Bank transfers
Direct bank-to-bank transfers through National Electronic Funds Transfer (NEFT) or Real-Time Gross Settlement (RTGS) services are often used for large transactions.
