What is a Payment Gateway?
A payment gateway is a technology that facilitates online transactions by transferring payment information between a customer, merchant, and the respective banks. It encrypts sensitive data such as credit card numbers to ensure that information passes securely between the customer and the merchant.
Why Are Payment Gateways Important in India?
India’s digital economy is growing rapidly. With initiatives like Digital India and UPI, even small vendors have gone online. Payment gateways are critical because they:
- Enable instant digital payments.
- Support multiple payment methods (UPI, cards, wallets, net banking).
- Offer fraud detection and security layers.
- Improve customer trust and conversion rates.
