These spots are protected from weather and tampering, making them perfect for safety instructions, emergency contacts, or in-car service menus.
   • Exterior Placement: Best for engaging pedestrians, customers, or passersby. Mount the QR code on the front or rear windshield where it’s clearly visible but does not obstruct the driver’s view. For fleet vehicles or promotional cars, side windows can also be effective. Ensure the code is positioned at eye level and unobstructed by wipers, decals, or tint lines.
   • Use Case Alignment: If the goal is customer interaction (e.g., linking to a website or social media), exterior placement is preferable. For internal use—like driver logs or vehicle diagnostics—interior mounting is more appropriate.
2. Size Considerations

   The physical dimensions of your QR code must match its intended scanning distance and environment:

   • Long-Range Scanning: For codes viewed from several feet away (e.g., on parked cars), use larger formats—minimum 4x4 inches (10x10 cm). This ensures smartphone cameras can detect and decode the pattern even at a distance.
   • Close-Up Scanning: For dash-mounted or interior codes, a smaller size (2x2 inches or 5x5 cm) is sufficient, as users will scan up close.
   • Proportional Scaling: Always scale the QR code proportionally to avoid distortion. Never stretch or compress the image, as this can render it unscannable.
   • View Obstruction: Avoid placing large codes near critical visibility zones such as the lower corners of windshields or near side mirrors. Safety should always take precedence over marketing goals.
3. Simplicity and Data Efficiency

   A simple, clean QR code is more reliable and faster to scan:

   • Static vs. Dynamic Codes: Use static QR codes (which contain fixed URLs) for permanent installations. They produce simpler, cleaner patterns and don’t require ongoing maintenance. Dynamic codes, while editable, often include tracking parameters that increase complexity and reduce scannability on small screens.
   • Data Minimization: Keep the encoded URL short. Use URL shorteners (like Bitly or Rebrandly) to reduce character count and improve code readability.
   • Error Correction: Choose a QR code generator that allows you to set error correction levels (preferably Level Q or H), enabling the code to remain functional even if partially damaged or dirty.
4. Weather Resistance and Durability

   Outdoor QR codes face environmental challenges that can degrade performance:

   • Waterproof Protection: If placed externally, encase the QR code in a transparent, waterproof sleeve or laminate it with a UV-resistant sealant to prevent water damage, fading, or peeling.
