Even the fingerprint readers that check pulse and temp can be foiled by
the gummi bear attack. Or other variations on silicon tips. Only
biometric fingerprint readers that can also check oxygenation, a la the
sensor that hospitals use on patient fingertips, would be less prone to
this approach.

Though arguably if you have biometrics, you can at least outrun the other
guy, if not the bear himself.
