Abstract
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.
