Create UPI QR Codes for Instant Payments.

How Universal UPI QR Codes Work: The NPCI Specification Explained

Underneath every scannable payment QR code lies a standardized Uniform Resource Identifier (URI) defined by the National Payments Corporation of India (NPCI). When a customer scans your printed or digital QR code using any Indian payment app, the scanner parses this URI string and opens a native payment flow.

Key parameters encoded within standard UPI QR codes include:

• pa (Payee Address / VPA): The recipient's Virtual Payment Address (e.g. 9876543210@ybl or store@okicici).
• pn (Payee Name): The official individual or business name displayed on the customer's phone screen during transaction confirmation.
• am (Amount): An optional fixed transaction amount in Indian Rupees (INR). Leaving this blank allows customers to manually type any payment sum.
• cu (Currency): Set to INR by default for all Indian banking networks.
• tn (Transaction Note / Memo): An optional remark or invoice identifier displayed in bank statements and app payment receipts.

Because our universal UPI QR generator strictly builds native NPCI URIs without routing through third-party redirect links, payments transfer instantly from customer bank accounts directly into your linked bank account with zero middleman fees.

Flexible Payment Routing: UPI ID vs Direct Bank Account & IFSC

Fixed Amount QR Codes: Speed Up Counter Queues & Eliminate Typos

One of the biggest operational friction points for billing counters and retail stores is manual customer amount entry errors—such as a customer accidentally paying ₹50 instead of ₹500, or vice versa.

Using our UPI QR code generator with amount feature, merchants can lock in exact payment sums (in INR ₹) alongside specific order numbers or invoice IDs. When a customer scans the QR code:

• The payment app pre-fills the specified INR amount automatically.
• The payment amount field is locked or highlighted, preventing customer typographical mistakes.
• The custom memo note appears on the customer's bank statement, enabling seamless accounting reconciliation for your business.

Step-by-Step Guide: How to Generate, Customize & Export Your QR Code

Creating a custom, print-ready UPI payment QR code takes less than 30 seconds. Follow these 4 simple steps:

1. Provide Payment Details: Enter your UPI ID / VPA or your Bank Account Number + IFSC Code. Type your official merchant or business name.
2. Add Transaction Parameters (Optional): Enter a fixed INR payment amount if creating a product-specific QR code, or add an invoice memo string.
3. Customize Brand Center Logo & Styling: Select a center logo overlay (Google Pay, PhonePe, Paytm, BHIM, Amazon Pay, or CRED) or upload your own custom business logo. Tailor the QR code foreground and background colors to match your brand identity.
4. Download High-Res Assets or Print Poster:
   • 2000px High-Resolution PNG: Crisp raster image optimized for digital invoices, websites, and high-DPI smartphone display.
   • Scalable Vector SVG: Infinite resolution vector graphic for professional print shops, banners, and vinyl stickers.

Pro Tips for Maximum QR Code Scanning Reliability

To ensure your printed or displayed QR codes scan instantly across all phone cameras and payment applications, keep these best practices in mind:

• Maintain Strong Contrast: Always use a dark foreground pattern (black or dark navy) on a clean, solid white background. Avoid low-contrast color combinations.
• Avoid Overcrowding Logos: When embedding custom center logos, ensure the logo size does not cover essential QR error-correction patterns. Our tool automatically sets safe logo margins.
• Print at Adequate Sizing: Counter standees should feature a QR code pattern of at least 2 inches × 2 inches (5cm × 5cm) so customer phone cameras can scan from a comfortable distance.
• Test Before Mass Printing: Always scan your generated QR code with Google Pay, PhonePe, and Paytm on a smartphone screen before sending artwork to physical print shops.
