Thank you for your question today, I look forward to assisting you. I bring nearly 20 years of legal experience in various disciplines.
There is currently no law making your finger print legally private for this sort of purpose. Employers all over have started adding these sorts of bio-recognition features and no court has yet ruled that it is illegal.
So, unfortunately, unless and until someone successfully takes this issue to a court high enough to get the attention of the Supreme Court, the rules on the issue are very disjointed.
So, as it stands, it is not presently illegal.
