    Pretty much this. A 0.02% error margin when there are tens of thousands of visitors per year, means it’s almost guaranteed to have errors.

    99.9% ^700 = 49.6% chance of no errors occurring.
    99.98% ^3466 = 50% chance of no errors occurring.
    99.98% ^23000 = 1% chance of no errors occurring.

      Pretty much that. The customer wanted to use it for identification and authentification in one go, with lenience for dirty and injured fingers on top.
