QR codes can either be static or dynamic. As their name implies, static or fixed QR codes are unchanging and cannot be edited once live. With static QR codes, one specific set of data or information is ingrained into the code.
Dynamic QR codes on the other hand redirect users to a specific URL, which can be changed at any time. One of the many benefits of dynamic QR codes is their ability to gather scanning metrics, such as the time, location, and device used to scan the code.
