Open your phone's camera app, point it at the QR code, and hold steady for 2-3 seconds. When the code is recognized, a notification banner or link will appear. Tap on it to access the QR code's content. Make sure you have enabled QR code scanning in your camera settings if available.

Yes, you can scan QR codes from images or screenshots using online QR code scanners like ScanQR.org or Google Lens. Simply upload or drag and drop the image containing the QR code, and the scanner will decode the information.

The safest options are: 1) Using your phone's built-in camera app 2) Using reputable security-focused apps like Kaspersky QR Scanner that check for malicious content 3) Avoiding third-party scanner apps that request unnecessary permissions or charge suspicious subscription fees.

QR codes can contain various types of information including URLs, plain text, contact cards, PDFs, email addresses, phone numbers, Wi-Fi network details, calendar events, product information, and even pre-filled text messages.
