What is a Payment Processor?
Have you ever wondered what happens behind the scenes to make your debit or credit card payment go through successfully? This is where a payment processor acting as your middleman between your merchant, customer, and the bank comes into the scene to ensure every transaction done on your portal is secure, thereby providing a smooth experience to your customers.
When every payment is processed successfully from the customer’s account to the merchant’s, it truly feels proud to see the payment processor working in perfect harmony.
The payment processor is also responsible for cross-checking the validity and transaction limits of the credit card, as well as the overall transaction security. It enables the transaction to take place between the buyer and the merchant.
Example: When you buy an article online, the payment processor checks with your bank to ensure you have enough funds. Once confirmed, the payment processor transfers the amount to the merchant’s account securely within a few seconds.

Major Players in the Payment Processing System
Understanding the “payment processed” meaning is essential before exploring the major players in the payment processing ecosystem.
The Merchant (Seller)
For a merchant to accept payment, they need to partner with a payment gateway company that they can trust with their every transfer. A merchant cannot accept card payments without partnering with some key players. So if a merchant wants to incorporate cashless transactions in their business, they must partner with an acquirer or a merchant bank. A merchant account with an acquirer will enable them to approve and disburse payments.
The Customer (Cardholder)
For a merchant to receive secure payments, someone must be willing to pay. A merchant needs a customer with a working credit/debit card for payment to be processed from an issuing bank. A customer is someone who knows about the existence of the merchant and how to reach them. Only then can they pay for the merchant’s services/products. A customer will not trust the merchant unless he/she can trust the payment gateway system on the merchant’s platform.
The Card Network (Visa/Mastercard)
Visa and Mastercard are the world’s most renowned payment processing networks. It offers customers a wide range of prepaid, debit, and credit card options worldwide. It is a card network that connects merchants, their customers, and the banks associated with both.
Issuing Bank (Customer’s Bank)
An active customer account is essential to be able to send money to a merchant’s account. Once your bank verifies your details and the bank balance, it lets you transfer funds on NPCI’s request to the acquiring bank.
Acquiring Bank (Merchant’s bank)
The acquiring bank is entrusted with the job of crediting the receiver’s account on NPCI’s request. Once the amount is credited to the merchant’s bank account, the customer’s order is completed, and payment is processed successfully.
Payment Processors
A payment processor is an entity that takes on the responsibility of securely transferring the due amount from the customer’s bank account to the merchant’s bank account.

How Does UPI Payment Processing Work?

The app generates a device fingerprint to authenticate the user for easy usage in the future. - The user sets up a unique UPI ID and connects it to their bank account. The bank verifies the number provided using an SMS code.
- The user selects their bank account from the list of options, and the app sends a request to NPCI. The user enters card details, and once verified, the user sets a 4–6 digit UPI PIN. (Note: This PIN is unique to you and is not stored by banks; banks are meant only to store an encrypted hash.)

How do businesses offer wallets as a payment method to customers?
Well, businesses use payment aggregators or payment gateways that offer wallets as a payment mode. Tagging it as one of the fastest modes of payment.
In such a scenario, the payment processor itself acts as a wallet. E-wallets have been designed to improve customer convenience by making payments faster, simpler, and completely contactless. Here, the funds already exist in the wallet’s bank account. So, when a customer makes a transaction, the funds are debited from their ledger internally. In other words, there is no external stakeholder. Consequently, the transaction gets settled at the end of the day to the merchant’s business bank account.
