What is the difference between static and dynamic QR codes?
Static QR codes have the destination information permanently encoded into the code itself. Once generated, the destination cannot be changed—if you want to change where the QR code points, you need to create a new QR code and redistribute it. Dynamic QR codes use a short URL that redirects to your final destination, allowing you to change the destination anytime without changing the QR code image. Dynamic codes are perfect for: updating menus without reprinting, fixing errors in printed materials, A/B testing different destinations, seasonal campaigns, and version control. Utilvo supports both static and dynamic QR codes depending on the type.
How do I scan a QR code?
Scanning a QR code is instant and works on all modern smartphones. On iPhone (iOS 11+): Open the Camera app, point it at the QR code, and tap the notification banner that appears. The linked content opens automatically in the appropriate app or browser. On Android (8.0+): Open the Camera app or Google Lens, point it at the QR code, and tap the popup notification. The content opens directly. No special apps are required—your phone's built-in camera handles everything. The entire process takes 3-5 seconds from scan to content access.
