# What does Static and Dynamic QR codes mean?

Once generated, a Static Code cannot be edited and its scans cannot be tracked. Dynamic Code, on the other hand, is very flexible and virtually indestructible. You can update its content, change/add links, and fix typos; even after print. You can also track the number of scans, including where and when.
