Some states require unemployed people to use unreliable face recognition to prove their eligibility for unemployment support. Failures can cause delays of weeks.

This is a use of face recognition for which a perfectly reliable system would do no harm, provided it doesn't impose nonfree software on people. Applicants for unemployment support are required to identify themselves, after all. What worries me most about biometrics is the danger of using them to identify people when they are entitled to anonymity.
