What is a QR code?
A QR code (Quick Response code) is a two-dimensional barcode that can store various types of information including URLs, text, contact details, WiFi credentials, and more. Unlike traditional barcodes that only store numerical data, QR codes can hold much more information and can be scanned quickly using smartphone cameras.
Are QR codes free to create and use?
Yes! QR codes are completely free to create and use. The QR code specification is open and free to use, which means anyone can generate QR codes without paying licensing fees. Our QR Code Zebra generator is 100% free with no hidden costs, watermarks, or usage limits.
Do QR codes expire?
Static QR codes (like the ones generated by our free tool) never expire. Once created, they will continue to work indefinitely as long as the linked content remains accessible. However, dynamic QR codes can expire or be updated through specialized services.
Are QR codes safe to use?
QR codes themselves are inherently safe - they are simply patterns that store data. However, safety depends on what the QR code links to and where you scan it from. Always preview URLs before visiting and only scan codes from trusted sources.
Can QR codes be tracked?
Static QR codes (like those from our free generator) cannot be tracked because all data is stored directly in the code itself. However, tracking is possible with dynamic QR codes through specialized services that can track number of scans, geographic location, and device types.
