> Since there is nothing genetic about fingerprints While it's true that even identical twins don't have the same fingerprints [1], it's not true that there are no genetic factors in the general shape of fingerprints [2]. I agree that it's unacceptable if a fingerprint reader isn't good enough to distinguish identical twins based on the differences in fingerprints though, as those should be the most similar fingerprints possible, essentially setting a floor on the minimum uniqueness in the problem. It seems like they would use identical twin derived validation data sets to ensure this. 1. https://www.nytimes.com/2004/11/02/health/the-claim-identical-twins-have-identical-fingerprints.html https://www.nytimes.com/2004/11/02/health/the-claim-identica... 2. https://www.mcgill.ca/oss/article/did-you-know/you-inherit-part-your-fingerprint-your-parents https://www.mcgill.ca/oss/article/did-you-know/you-inherit-p...
