Our recent outing we caught few dinks went to open my phone, my 13yr son set it up for finger print unlock. Well that don't work on a raw thumb(finally got in with the code). Next day at work we have to thumb a time clock, well raw thumb still in effect. luckily I had the index finger as a back up. just thumb-thing to think about.
Tell your boss "well I can't get clocked in because my thumb is raw. I probably won't be able to clock in until about mid November". You can thank me later.
