A QR (Quick Response) code is a two-dimensional barcode that can store various types of information like URLs, text, contact details, WiFi credentials, and more. It can be scanned using smartphone cameras to quickly access the encoded information.

How do QR codes work?

QR codes store data in a pattern of black and white squares. When scanned by a smartphone camera or QR reader app, the pattern is decoded to reveal the stored information, which can then be used to open a website, display text, connect to WiFi, save contact details, etc.

Are QR codes free to use?

Yes, QR codes are free to generate and use. There are no licensing fees or restrictions. You can create unlimited QR codes for personal or commercial use without any cost.

What are the different types of QR codes?

Common QR code types include: URL QR codes (website links), Text QR codes (plain text), Email QR codes (email addresses), Phone QR codes (phone numbers), WiFi QR codes (network credentials), Contact QR codes (vCard), and SMS QR codes (text messages).

How to scan a QR code?

Most modern smartphones have built-in QR code scanning in their camera apps. Simply open the camera app, point it at the QR code, and tap the notification that appears. Alternatively, you can use dedicated QR code scanner apps available on app stores.

Can QR codes be tracked?

Yes, dynamic QR codes can track scans, location, device type, and timing. Static QR codes cannot be tracked. If you need analytics, use dynamic QR code services that provide scan statistics and analytics dashboards.

QR codes themselves are secure, but you should be cautious when scanning codes from unknown sources. Malicious QR codes can redirect to phishing websites. Always verify the source and check the URL before entering sensitive information.
