A multi-biometric finger sensor may include infrared sensing pixels on an
integrated circuit substrate for sensing infrared radiation emitted from
the user's finger, and at least one other finger biometric characteristic
sensor on the integrated circuit substrate for sensing a finger biometric
characteristic different than the infrared radiation emitted from the
user's finger. The sensor may also include a processor connected to the
plurality of infrared sensing pixels and the at least one other finger
biometric characteristic sensor. Each of the infrared sensing pixels may
include at least one infrared antenna and at least one temperature sensor
connected thereto.
