I'm wondering if there are known issues and if so hopefully known fixes, for the T series fingerprint readers.
The reader on my T480 is woefully unreliable- I have to make multiple attempts to use it, and usually takes 3 tries to get it to recognise a fingerprint (half the time I run out of attempts and need to use a password.)
I've tried re-registering my fingerprints multiple times, a combination of hard and light touches. A friend with another T480 reports the same problems. My old Thinkpad, an X201 with a swipe-style reader, worked with close to a 100% accuracy.
I thought this would be a common issue, but online searches only return results for broken readers or readers that have been totally borked by the OS.
At this rate, I am going to go back to just using a password, but hopefully someone has some useful advice for this issue.
After downloading and installing another driver it works 100% every time.
Try another driver is my best advice.

T510 i5 4384-DV7
T510 i7 4349-A64
T520 i7QM 4242-4UU Highly Modified
Oddly, the driver appeared to be correct, but I downloaded and reinstalled the same driver again, and from my ten or so tests just now, accuracy has gone up alot. 8 out of 10 attempts registered correctly, with the two failures being deliberately bad finger placements.
Very weird. Both pre and post driver was:
