In my 15 years of following BIO-key, I cannot remember a time when they have been a “must”. Especially in a large-scale government or regulated industry. One significant issue, is that the fingerprint templates created by BIO-key fail NIST MINEX III compliance tests.
As of June 2020, BIO-key is no longer a participant in MINEX III, which is the source of truth for fingerprint matching accuracy.
Clearly, they’d rather not participate in 3rd party validation than be on record as FAILing the official NIST tests.
