Unified Payments Interface (UPI), developed by the National Payments Corporation of India (NPCI), utilizes a standardized URI scheme upi://pay to trigger inter-bank fund transfers across mobile payment apps. The canonical structure includes:
pa (Payee Address / Virtual Payment Address): The recipient VPA (e.g. merchant@okhdfcbank, name@upi).pn (Payee Name): The legal registered entity or individual name displayed to the payer before biometric authorization.am (Transaction Amount): Float formatted with exactly 2 decimal places (e.g. 150.00).cu (Currency Code): Standard ISO 4217 currency code (default: INR).tn (Transaction Note): Order ID, invoice reference, or memo displayed in passbooks.mc (Merchant Category Code): 4-digit ISO 18245 code required for commercial settlement.Most online UPI QR generators route payment details through cloud analytics backends, logging customer VPAs, purchase memos, and invoice totals. VedKit generates 100% client-side QR codes inside HTML5 Canvas in browser RAM.
