NPCI UPI Payment QR Generator: Deep Link Specifications, Merchant VPAs & Printable Standees
India’s Unified Payments Interface (UPI), developed by the National Payments Corporation of India (NPCI), processes billions of digital transactions monthly. For shopkeepers, freelancers, billing desks, and charitable institutions, collecting customer payments requires standardized, error-resilient payment QR matrices. Scanning a faulty or misconfigured UPI QR causes bank PSP routing failures, transaction declines, or funds misdirection. The Kriyasya UPI QR Generator creates fully compliant Bharat QR and NPCI UPI deep-link matrices supporting static payee profiles, dynamic transaction-specific invoicing, and print-ready checkout standees compatible with Google Pay, PhonePe, Paytm, BHIM, and all banking apps.
The Protocol Architecture: NPCI UPI Deep Link Specification
The internal string embedded within the QR matrix conforms to the formal NPCI UPI Linking Specifications:
Standardized URI query parameters dissected:
- pa (Payee Address): The merchant’s registered Virtual Payment Address (e.g.,
kriyasya@iciciormobile@upi). This is the mandatory routing target. - pn (Payee Name): The official legal or trade entity name as registered with the acquiring bank. Displayed to the customer on their banking screen prior to biometric authorization.
- am (Transaction Amount): An optional parameter specifying the exact billing amount in Indian Rupees (INR). If left blank, the customer enters the amount manually.
- cu (Currency Code): Mandatory sovereign currency identifier, strictly set to
INR. - tn (Transaction Note): Contextual remarks or order identification (e.g., Bill No 4821) that appears on both customer and merchant passbook bank statements.
Static vs. Dynamic UPI QR Deployment Scenarios

Frequently Asked Questions
Are payments received through this QR code subject to gateway charges?
No. This generator creates direct NPCI UPI deep links that route payments straight between the customer’s bank account and your VPA bank account, bypassing third-party aggregator processing cuts.
Can I fix a specific billing amount in the UPI QR code?
Yes. Entering an amount locks the payment sum in the customer’s payment app, eliminating human entry errors during billing.
