Frequently Asked Questions About QR Codes
What is a QR code?
A QR code (Quick Response code) is a two-dimensional barcode that stores data in a grid of black and white squares. Smartphones can scan QR codes using the built-in camera app to open websites, join WiFi networks, save contacts, view documents, and more.
How do I scan a QR code?
Open your smartphone camera and point it at the QR code. Most modern phones (iPhone iOS 11+ and Android 10+) automatically detect and read QR codes without any third-party app. A notification or link will appear that you can tap to take action.
What is the difference between static and dynamic QR codes?
Static QR codes embed data directly in the image and cannot be changed after creation, but they work forever. Dynamic QR codes use a redirect URL so you can update the destination anytime and track scan analytics. Learn more in our detailed comparison.
Are QR codes free to create?
Yes. Every new account starts with a 3-day free trial — no credit card required. Create up to 5 dynamic QR codes with custom branding. After the trial, paid plans start from $5/month to unlock more codes, static QR codes, and analytics. One-time static QR codes are also available from $1 each.
Do QR codes expire?
Static QR codes never expire because the data is encoded directly in the image. Dynamic QR codes remain active as long as your subscription is active. One-time purchase QR codes from QRCodeStack work forever with no expiration date.
