Frequently Asked Questions
What can I encode in a QR code?
QR codes can encode text, URLs, email addresses (mailto:), phone numbers (tel:), SMS messages, WiFi credentials, vCards (contact info), calendar events, and more. URLs are the most common use case.
What size should my QR code be?
For print materials, QR codes should be at least 2cm x 2cm for reliable scanning. Larger codes scan better from greater distances. For business cards, 150-200px is usually sufficient.
Can QR codes expire?
Static QR codes (like the ones this tool generates) never expire. However, if the QR code links to a URL, ensure that URL remains active for the QR code to remain useful.
