Designing UPI – System Design
Designing a Unified Payments Interface (UPI) system involves creating an architecture that enables real-time inter-bank transactions through a seamless and secure platform. Key components include user interfaces, a central UPI switch managed by the National Payments Corporation of India (NPCI), backend systems of participating banks, and third-party service providers.
- The system supports core functionalities such as user registration and authentication, payment initiation and authorization, inter-bank transaction processing, and real-time settlement.
- Security measures like encryption and multi-factor authentication ensure compliance and protect against fraud, making UPI a reliable and efficient payment solution.
- The UPI is a real-time payment system that facilitates inter-bank transactions by instantly transferring funds between two bank accounts on a mobile platform.
