Frequently Asked Questions
What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that stores data in a matrix of black-and-white squares. It can encode URLs, text, contact information, WiFi credentials, and more. Most modern smartphone cameras can scan QR codes natively.
Can QR codes store WiFi passwords?
Yes. When you generate a QR code with the WiFi type, it encodes the network name (SSID), password, and encryption type (WPA/WEP) into a standard format. Scanning it with a phone camera will prompt the user to join the network automatically.
Are QR codes safe to scan?
QR codes themselves are harmless — they are just data. However, the URL or data they point to could be malicious. Always verify the URL before entering personal information. Most browsers now show a preview of the URL before opening it from a QR scan.
