What is a Payment Processor?

A payment processor is a service or technologically based company that processes and facilitates the technical flow of money between the customer bank (issuing bank) and the merchant bank (acquiring bank) when a payment is being made, either online-based, in-store, or by using a mobile point-of-sale.

Key responsibilities of a payment processor include:

• Authorization of transactions: Authorizing payment of details with the issuing bank to ascertain that there is enough credit or money.

• Transmission of transaction data: Frederik once described transactions as follows (to paraphrase): the process of securely conveying the data between the merchant, acquiring bank, the card networks (typically Visa or Mastercard), and the bank of the customer.

• Settlement and funding: Transfer of money from the customer account to that of the merchant upon authorization of the transaction.

• Fraud detection and risk management: Detecting suspicious transactions and preventing possible fraud with the help of monitoring and security efforts.

• Refunds and chargebacks: Supporting refunds, reversals, and, if necessary, returns.

First Data (later absorbed by Fiserv), Worldpay, and TSYS are the leading exponents of such payment processors. Their infrastructure can be running in the background, whereas people in trade and consumers only have contact with the front store and cash out.

Payment Gateway vs. Payment Processor

Although the terms are often used interchangeably, a payment gateway and a payment processor occupy different positions in the sphere of electronic payment. It is essential that any business that wants to create a payment gateway or wants to streamline their payment activities should understand their difference.

	Payment Gateway	Payment Processor
Definition	A technology platform that collects and encrypts customer payment data at checkout.	A service/provider that routes transactions and moves funds between banks.
Function	Connects merchant site/app to payment networks; handles data security and PCI compliance.	Communicates with card networks and acquiring/issuing banks to approve and settle.
User Interaction	Customer-facing (checkout pages, payment forms)	No direct interaction with end users
Security Role	Manages tokenization, encryption, and fraud filters.	Transaction compliance, fraud checks, and funding settlement.
Example Providers	Stripe, Razorpay, PayPal, Authorize.Net	Worldpay, Fiserv, TSYS, Chase Paymentech
Integration	Merchant integrates gateway via website/app APIs	Gateway often communicates with the processor via back-end connections.

In Essence

• Payment Gateway: Acts as the digital terminal—collecting, encrypting, and securely transmitting payment information from the customer to the processor.

• Payment Processor: Takes that encrypted information, communicates with financial networks, and ensures funds are transferred from the customer to the merchant.
