Why is vector SVG better for printing QR codes?

Vector SVG uses geometric paths rather than fixed pixel grids. When scaled to large posters, vinyl banners, or tiny business cards, vector QR codes maintain razor-sharp mathematical edges with zero blur or compression artifacts, ensuring maximum camera scannability.

How does Error Correction Level (ECL) protect QR scanability with logos?

QR codes use Reed-Solomon error correction. Level H allows up to 30% of the QR matrix area to be damaged, obscured, or covered by a central brand logo while retaining 100% data recoverability by any smartphone camera.

What is the required Quiet Zone around a QR code?

ISO/IEC 18004 standards mandate a minimum Quiet Zone margin of 4 modules of clean background space around the QR code matrix to allow scanner image sensors to isolate finder patterns from surrounding artwork.

Common Questions

Frequently Asked Questions

Does scanning the QR code immediately place the phone call?

No. For security and to prevent accidental dials, scanning the QR code opens the smartphone’s native Phone app with the number pre-filled. The user must tap "Call" to initiate the phone call.

Should I include the country code in the phone number?

Yes, we strongly recommend including the international country code (e.g., +1 for United States / Canada, +44 for UK, +91 for India). This guarantees the QR code works seamlessly regardless of where the scanning user’s phone is registered.

Are phone numbers stored or tracked on your servers?

No. All QR code generation is performed 100% on the client side in your browser. No phone numbers are recorded, transmitted, or logged on any server.

How small can I print a phone QR code?

Because a "tel:" payload is very short (around 15-20 characters), the resulting QR code matrix is very compact (Version 1 or 2). It can be printed reliably as small as 0.7 × 0.7 inches (18 × 18 mm) on business cards.
