Benefits of UPI and Dynamic QR Codes for Merchants and Freelancers
The Unified Payments Interface (UPI) standard enables instantaneous, zero-fee direct-to-bank electronic transfers. Having a dedicated, high-contrast QR code printed at your retail counter or embedded on an invoice guarantees frictionless transactions from Google Pay, PhonePe, Paytm, and BHIM applications.
Best Practices for Printing Your QR Codes:
- Maintain High Contrast: Ensure high contrast between the foreground pattern (dark color) and background (light or white) so all smartphone cameras can read the matrix instantly.
- Adequate Physical Size: For store counters or tabletop display, print at minimum 3 inches by 3 inches (7.5cm x 7.5cm).
- Durable Lamination: Laminate paper prints to protect them from dust, humidity, and scratches that could damage key alignment squares.
