1. An infrared finger sensor apparatus comprising:
an integrated circuit substrate for receiving a user's finger adjacent thereto;
a plurality of infrared sensing pixels on said integrated circuit substrate for sensing infrared radiation naturally emitted from subdermal features when the user's finger is positioned adjacent said integrated circuit substrate; and
a processor connected to said plurality of infrared sensing pixels for generating infrared biometric data based upon infrared radiation naturally emitted from the subdermal features of the user's finger.
