Understanding how UPI works

Unified Payments Interface  is a real-time payment system developed by the National Payments Corporation of India (NPCI). It allows users to link multiple bank accounts to a single mobile application, providing a seamless and secure way to transfer funds. It works on a “virtual payment address” (VPA) system, where users can create a unique identifier that is linked to their bank account. This VPA eliminates the need for sharing sensitive bank account details during transactions, making UPI a secure payment method.

To initiate a transaction, users need to download a UPI-enabled mobile application provided by their respective banks or third-party payment apps. Once the app is installed, users can create a VPA and link their bank account(s) to the UPI app. The app provides a user-friendly interface where users can send and receive money, pay bills, and make online purchases seamlessly. UPI transactions can be initiated using various methods such as VPA, mobile number, and QR codes, making it accessible to users with or without smartphones.

UPI transactions are processed in real-time, allowing users to instantly transfer money to their contacts or merchants. The funds are transferred directly from the sender’s bank account to the recipient’s bank account, eliminating the need for intermediate wallets or third-party payment gateways. This direct transfer feature makes UPI transactions faster and more convenient compared to traditional payment methods.
