An online payment system is a digital infrastructure that enables users to pay for products or services securely over the internet. These systems support bank cards, e wallets, mobile payments, virtual POS terminals, Apple Pay, Google Pay, and other payment technologies, ensuring a fast and seamless transaction process.

How an online payment system works:

1. The customer selects a product and proceeds to checkout.

2. Payment details are entered - card number, CVV, expiration date.

3. The system encrypts the data and sends it to the bank server.

4. The bank performs 3D Secure verification or other security checks.

5. The payment is confirmed and the order is completed in real time.

6. Confirmation messages are sent via SMS and email.

Online payment systems deliver speed, security, and convenience for both businesses and customers. They are essential for e commerce platforms, SaaS tools, and mobile applications. A professional online payment system increases conversion rates, improves trust, and boosts overall sales performance.
