International Direct Carrier Billing (DCB) Payment Gateway

International Direct Carrier Billing (DCB) Payment Gateway

Overview

The international DCB payment gateway system enables mobile subscribers to use their airtime accounts (main account balance) to pay directly for digital services and items such as games, music, and applications on platforms like Google Play without needing a credit card or e-wallet. The system is tightly integrated with international service providers like Google and is connected with the internal systems of telecom operators to ensure high security and compatibility.

The integrated systems include a fraud prevention system to block abnormal transactions, an automatic credit system to maintain uninterrupted service for customers, a charging proxy system to ensure accurate billing, and a refund management system to handle refund requests swiftly. This DCB system offers users the convenience and high security of direct payments while allowing telecom operators to expand services and increase revenue through digital service payment transactions.
