@leeloo Mine don't meet the minimum entropy requirement.

Some people don't have fingerprints. By genetics, or wear (like working with acids).

And fingerprints can be "stolen" (IE: the patterns copied and simulated). It's been done.

@JeffGrigg I like to joke, but as I age, it does become less and less likely that my fingerprint will be read successfully. The reader for the time clock at work was the worst (which did include working with acids, as it happens....)
