Why do they not work though? I mean, the reader should just be reading a series of lines. Are they too close together in your case or something, or too twirly?

Why do they not work though? I mean, the reader should just be reading a series of lines. Are they too close together in your case or something, or too twirly? I appreciate that this may be a personal question but I hope you can overlook this given that we are on a semi-technical forum. It seems an interesting problem (though I am not a fingerprint engineer)
- yencabulator 6y agoPersonally, my fingerprints often fail to read the same way over some weeks of dry climate, especially if I've done any manual labor. And before you say anything about dry skin, putting lotion on is a temporary DoS attack on the fingerprint scanners I own, so that's not great either. I can re-train the fingerprints, and they work for some weeks again. A more successful workaround I've found is teaching the machine the side of my finger, not the pad.
- wenc 6y agoThanks for the tip. I have iPhones and iPads that have fingerprint readers and they all invariably fail to read my prints after a while (And I have 3-4 prints stored per finger). It’s frustrating. Sometimes it’s due to dryness but other times I have no explanation for. Face ID on the other hand has been robust.
