How a Payment Processor Works
A payment processor is an entity responsible for moving money from the customer account to the merchant account. The original role of these organizations was to help facilitate offline transactions like credit card payments. With the advent of the internet and electronic payments, they continue to perform this role. Payment processors are the ones who provide credit card terminals or other Point of Sale (PoS) systems to merchants. In this offline system, the payment processor plays the role of the messenger while the PoS acts as the security/gatekeeper.
The purpose of a PoS terminal is to verify that the transaction is being conducted with an authentic credit card, presented by a genuine owner of the card/account. Authentication in these situations relies on a combination of an EMV chip embedded in the credit/debit card, and approval from the customer.
Next, the payment processor will send the payment information to the issuing bank. One of two things can happen at this point – if the bank approves the transaction, the processor sends the transaction details to the acquiring bank and communicates the success of the transaction to the customer at the PoS terminal.
If the bank declines the transaction for any reason, like lack of credit balance/funds, the payment processor will relay the details to the customer via the PoS terminal.
Payment Gateways and Payments Online
A payment processor performs the same “messenger” role in an online transaction much like an offline one. But in the online setting, there is no secure PoS device to act as the authenticator. This is where a payment gatekeeper comes into the equation. In essence, a payment gateway is a software or technological platform that provides a secure, encrypted connection between a merchant’s online website or hosted payments software, and major credit card processing companies.
The need for an electronic “gatekeeper” for transactions only arose in the 1990s, after online payments and debit cards became a reality. A payment gateway is like a virtual PoS terminal, tasked with the duty of authenticating a digital payment request by the customer.
Instead of inserting a physical card into a physical terminal, the customer has to enter credit card information and identifying details as proof of authenticity into the payment gateway’s customer-facing interface. If the credentials are correct, the gateway will forward the payment information to the payment processor.
From this point onwards, the transaction works just like in an offline, in-person card transaction where the payment processor securely transmits the transaction data between the merchant and customer banks. Upon successful completion of the fund transfer, the processor shares the details with the customer via the gateway.
Understanding the Choice Between Payment Processors & Payment Gateways
As the payment landscape evolves, merchants have more choices than ever when it comes to taking payments. While some payment gateways are available as standalone platforms, many modern gateways come as an integrated service offered by a major payment processor. Authorize.net, CyberSource, and USAePay operate as standalone gateways that connect to several different processors on the back end. Worldpay / Vantiv, PayPal, and Stripe are examples of processors that also have in-house gateway solutions.
Enterprise organizations may opt to use multiple processors and gateways to ensure maximum coverage in terms of payment volume, payment methods accepted, currencies, and global reach. For smaller merchants, a single integrated payment service is often the most reasonable choice.
When choosing a payment gateway or payment processor (or more than one), there are some notable trade-offs with each option. Using multiple gateways and processors comes with increased fees and other ancillary costs. Having an in-house gateway platform gives you more control, but requires extra maintenance. With a more affordable all-in-one platform, you get limited coverage and less control over data.
