Printing Dynamic UPI QR Codes on B2C and B2B Invoices: NPCI & GST Guidelines

Static vs Dynamic QR Codes: The Counter Speed Difference

Most retail stores place a static cardboard or acrylic QR standee on their counter. Customers scan it, ask "Kitna hua bhaiya?", manually type the amount (often making mistakes), and wait for verbal confirmation. A dynamic QR code printed directly on the bill contains the exact bill amount, invoice number, and VPA encoded inside it, so the customer simply taps 'Pay' with fingerprint auth.
