Payments

Quick Definition

A Payment Gateway is a technology that securely processes online payments by transferring payment information between a customer, merchant, and bank.

Detailed Explanation

A Payment Gateway acts as a bridge between a website/app and the bank, enabling customers to pay using credit cards, debit cards, UPI, or net banking.
