Fingerprint unlock amongst some crowds is seen as the 'posh' option because it means you still have soft skin from an office job.
Not to say that it doesn't happen, but most forms of manual labor don't wear down, scar, callous, or otherwise alter one's fingerprints enough to break it. In any case, this is why we all use backup fingers and toes.
Unsurprisingly, I found it significantly more difficult to "read" braille with my left hand because the calluses from playing guitar had reduced the tactile sensitivity in my fingertips.
