Something I’ve noticed about biometric fingerprint readers. They don’t work well after a bath. Why is that? Are our fingers different after a bath? I mean, they look different — all wrinkly, for one thing — but why does that mess up the fingerprint reader? I do my best thinking in the bath, and it’s getting frustrating to have to wait five minutes while my fingers return to normal before I can gain access to my computer. That’s the sort of warning they should put on the box.
