Frequently Asked Questions
What data can I encode in a QR code?
QR codes can encode plain text, URLs, email addresses, phone numbers, Wi-Fi credentials, vCard contacts, and more. The maximum capacity is about 4,296 alphanumeric characters.
What size should a QR code be for printing?
For reliable scanning, a printed QR code should be at least 2 cm × 2 cm (about 0.8 inches). For scanning from a distance, increase the size proportionally.
Do QR codes expire?
Static QR codes never expire — the data is encoded directly in the pattern. Dynamic QR codes (which redirect through a service) can expire if the service is discontinued.
