I'm looking for some samples of "scan" button like what you see below. I don't know what to search.Do they use Gifs?how can I find some examples?Some of them have really interesting animations both when you click on it and when you don't and they are fixed (they repeat an animation).
here is some examples.They are some pictures that I found from google.They are just to give a tip about what I want. Thanks in advance.
