What Is a Payment Gateway?
A payment gateway is a technology platform that securely captures, encrypts, and transmits your customers’ payment information during online or in-store payments. It acts as the digital cashier connecting your checkout system with payment processors and banks to authorise payments. Unlike merchant accounts, which hold and transfer funds, the payment gateway facilitates the secure flow of payment data. For more details on merchant-specific solutions, see our Merchant Payment Gateways guide.
Payment Gateway Meaning: Software or service that authorises and processes payment transactions by encrypting sensitive card data and forwarding it securely between the customer, merchant, and banks.
How Payment Gateways Work: The payment gateway captures payment details at the checkout page, encrypts the data, and forwards it to the payment processor, which communicates with the customer’s bank account to approve or decline the transaction.
How Payment Gateways Work
The payment gateway process involves several key steps to ensure secure and efficient payment processing:
- Customer Enters Card Details: On a secure payment page, customers input their credit or debit card information or select a digital wallet such as Google Pay.
- Payment Gateway Encrypts the Data: The payment gateway encrypts sensitive payment data immediately using protocols like SSL/TLS to prevent unauthorised access.
- Payment Processor Authorises Transaction: The encrypted data is sent to the payment processor, which routes it to the acquiring bank.
- Issuing Bank Approves: The customer’s issuing bank verifies the transaction, checks funds availability, and approves or declines payment.
- Funds Are Settled: If approved, funds are transferred to the merchant account and subsequently settled into the business bank account, usually within 1 to 3 business days.
This entire online payment processing flow typically completes within seconds, providing a seamless experience for customers and businesses alike. To understand how this fits with broader electronic transactions, visit our Online Payment Platforms page.

Payment Gateway vs Payment Processor
Although the terms are often used interchangeably, a payment gateway and a payment processor perform very different roles in the payment process.
A payment gateway is the technology that securely collects and encrypts a customer’s payment details during checkout. It then sends that information to a payment processor for authorisation.
A payment processor works behind the scenes to verify the transaction and transfer payment information between the customer’s bank, the card network, and the merchant’s bank.
In simple terms:
- The payment gateway handles the checkout and securely transmits payment data.
- The payment processor verifies the transaction and moves the funds between banks. Learn more about how processors work in our Payment Processors UK guide.
Most modern payment providers combine both services into a single platform, allowing businesses to accept payments through one integrated solution.
Types of Payment Gateways
There are three main types of payment gateways, each suited to different business needs:
Hosted Payment Gateways: Customers are redirected to a secure payment page hosted by the gateway provider. This reduces the merchant’s PCI compliance burden because sensitive card data is handled on the provider’s secure servers rather than on the business website.
While hosted gateways can add an extra step to the checkout process, they are widely used by online retailers that want a quick and secure way to accept card payments without managing complex payment infrastructure.
Hosted solutions are commonly used by online stores and integrate easily with many ecommerce platforms. Businesses looking to accept payments through an online shop can explore different ecommerce payment gateways to find providers that support their platform and payment requirements.
Examples: PayPal, Stripe Checkout
Integrated Payment Gateways: The payment form is embedded directly on the merchant’s website or app, offering a seamless user experience but requiring strict PCI compliance.
Examples: Stripe, Adyen
Self-Hosted Payment Gateways: The merchant’s own servers handle payment data processing, providing full control but requiring significant security measures.
