Frequently Asked Questions
What can a QR code store?
URLs, plain text, email addresses, phone numbers, SMS messages, Wi-Fi credentials (SSID and password), vCard contact cards, and payment links.
How much data can a QR code hold?
Up to 4,296 alphanumeric characters or 7,089 numeric digits. For URLs, shorter links produce smaller and more reliable codes.
Can QR codes be scanned directly from a screen?
Yes. Any modern smartphone camera app can scan QR codes displayed on a monitor, tablet, or TV screen without needing a dedicated scanner app.
Does QR code size affect scan reliability?
Yes. For print use, a minimum size of 2 cm by 2 cm is recommended. Larger, higher-contrast codes scan more reliably from greater distances.
