Frequently Asked Questions
Q:What data can QR codes contain?
QR codes can encode URLs, plain text, contact information (vCard), WiFi credentials (SSID/password), phone numbers, email addresses, calendar events, and more. They support up to approximately 4,000 characters depending on the data type.
Q:How do I scan the generated QR codes?
Use your phone's camera app (iOS/Android), a dedicated QR scanner app, or web-based scanner. Most smartphone cameras now detect QR codes automatically when pointed at the screen or printed code. Simply open your camera and point it at the QR code.
Q:Are QR codes secure for sensitive data?
QR codes contain data in plain text - anyone who scans them can read the content. Do not encode passwords, credit card numbers, or private keys. For WiFi sharing, note that network passwords are visible in the QR code to anyone who scans it.
