Frequently Asked Questions
How do Wi-Fi QR codes work when scanned by a phone?
Wi-Fi QR codes use the standard `WIFI:T:WPA;S:NetworkName;P:Password;;` protocol recognized natively by iOS (Camera app) and Android. When scanned, the smartphone automatically prompts the user: "Join this network?" and connects without manually typing lengthy passwords.
What is the best Error Correction Level for printed QR codes?
For standard flyers and digital screens, Level M (15%) is optimal. If printing on outdoor posters, restaurant tables, vehicles, or placing a logo in the center of the code, choose Level H (30%), which allows the code to scan even if up to 30% of the surface is damaged or obstructed.
What is the minimum recommended print size for a QR code?
For handouts, brochures, and business cards scanned from arm's length (30–40 cm), the minimum recommended size is 2 × 2 cm (0.8 × 0.8 inches). For posters and banners scanned from 2–3 meters away, the QR code should be at least 15–20 cm wide.
Can I download an SVG vector QR code for professional graphic design?
Yes. Click "Download SVG" to get an infinite-resolution vector file. Vector SVGs never lose sharpness, making them suitable for billboard banners, laser engraving, merchandise, and Adobe Illustrator/Figma workflows.
Do these QR codes ever expire?
Never. These are pure static QR codes where the data is encoded directly into the pixel pattern. Unlike paid subscription services that route through redirect links, these QR codes work permanently with zero monthly fees or expiration.
