How WhatsApp Click-to-Chat URI Scheme (wa.me) Works: Standards & Compatibility
WhatsApp QR codes utilize the official WhatsApp Click to Chat API (https://wa.me/<phone>?text=<encoded_message>). When scanned, smartphones immediately launch WhatsApp (or WhatsApp Business) and open a new chat window with the pre-drafted text ready to send.
https://wa.me/15551234567?text=Hi%2C%20I%20would%20like%20to%20inquire%20about%20your%20services.

Printing & Quality Guidelines
Follow these ISO/IEC 18004 recommendations to ensure instant, frictionless scans:
Maintain strong contrast: ensure dark foreground elements on a clean light background.
Observe the Quiet Zone: leave at least 4 modules of blank white margin around the QR code.
Test before bulk printing: scan the physical printed sample on both iOS Camera and Android Google Lens.
Use vector SVG for print production: SVG scales infinitely without pixelation on large signage or menus.
100% Client-Side Privacy Guarantee
QR Studio never stores, tracks, or analyzes your input payload. All matrix math, Reed-Solomon error correction encoding, and image rendering occur directly in your browser.
