    Tradeoff between speed & accuracy vs the amount of fingerprints. The data that would’ve been required to store a 5th is instead used to have better models of the other 4. Id rather have a faster reader that’ll read it right in more angles than an extra fingerprint when I only really use my thumb and index anyway. (Also you can totally train 2 different fingers in one “finger” and it’ll recognize both, just worse

      It literally took me less than 0.1 seconds to unlock my 7 year old phone with my toe.

      How impatient are you? FFS, the technology has been out there and pretty well refined for decades.
