Unified Payments Interface routing animation from sender MPIN verification to final ledger settlement switch.
The transaction starts when you input the recipient's UPI ID or scan their QR code. You enter your amount and authenticate the payment securely by inputting your 4 or 6 digit UPI MPIN (Mobile PIN).
The transaction starts when you input the recipient's UPI ID or scan their QR code. You enter your amount and authenticate the payment securely by inputting your 4 or 6 digit UPI MPIN (Mobile PIN).
Your mobile payment app (Payment Service Provider or PSP) requests debit clearance from your bank. The bank validates your account balance and locks the specified transfer funds immediately.
The debit confirmation is pushed to the National Payments Corporation of India (NPCI) central switch. NPCI acts as the interbank clearinghouse, resolving the recipient's virtual address and locating the payee's receiving bank.
NPCI directs a credit request to the recipient's bank. The receiver's bank completes the ledger credit and fires back an API credit confirmation to NPCI, which notifies both sender and recipient phones instantaneously.

Step 1: Initiate Transfer Request
Simulate entering a receiver UPI ID (VPA) or scanning a QR code and tap Send.
Step 2: Debit Bank Account
Watch your PSP Bank request debit clearance. Verify the secure MPIN credentials step.
Step 3: Route via NPCI Switch
Observe NPCI routing the transaction, resolving the virtual payment address, and locating the receiver bank.
Step 4: Credit Recipient Account
Follow the Credit request to the receiver bank. Watch the transaction complete with a successful green screen indicator.
The National Payments Corporation of India (NPCI) operates the central switch and routing infrastructure for UPI. It validates transaction details, maps virtual addresses (VPA) to actual bank account numbers, and ensures secure interbank clearing.
A Virtual Payment Address (VPA) is a unique identifier (like name@bank) that acts as an alias for a bank account. It allows users to send and receive money without sharing sensitive bank account numbers or IFSC codes.
UPI sits on top of the IMPS (Immediate Payment Service) network, which is integrated with bank ledger systems. Transactions are settled in real time, 24/7/365, using standardized secure API protocols.
