Frequently Asked Questions
What is the difference between a Static QR Code and a Dynamic QR Code?
**Static QR Codes** encode the destination URL or data directly into the black-and-white pixel matrix; they work forever without third-party servers and never expire. **Dynamic QR Codes** encode a short redirect link that routes through an intermediary server, allowing the destination URL to be edited later, but breaking if the hosting subscription lapses.
What size should a QR code be printed on physical flyers or posters?
The standard scanning distance ratio is **10:1**. A QR code scanned from 10 inches away should be at least **1.0 inch (2.5 cm)** wide. For posters scanned from 5 feet (60 inches) away, the QR code should be at least **6 inches (15 cm)** wide to ensure reliable camera auto-focus.
What color combinations should be avoided when designing QR codes?
Always maintain high contrast between foreground dots and background. The foreground must be significantly darker than the background (never invert with white dots on a yellow or light grey background). Avoid low-contrast pastel combinations, which cause camera sensors to fail.
How does vCard 3.0 work inside a QR code?
A vCard QR code contains formatted contact data (`BEGIN:VCARD ... END:VCARD`). When scanned by an iOS or Android smartphone, the device automatically opens the Contacts app with the person's name, phone number, email, company, and website pre-filled for 1-tap saving.
