I have scarring across my fingerprints that changes fairly frequently (serious injuries when younger coupled with powerlifting regularly now, unnoticable but definitely not static) I am an edge case but surprisingly only had infrequent issues.
I don't use thumb scanners anymore though as inevitably my finger will change! It definitely isn't for everyone.
