Payment Gateway

A payment gateway is a service that captures and routes payment information from a merchant to a payment processor or acquiring bank. It enables online and in-store payment authorization.

Gateways encrypt sensitive data and help merchants comply with security standards like PCI DSS. They often provide features like fraud screening and tokenization. Many gateways support 3D Secure to add issuer authentication for card payments.
