Abstract
A multi-biometric finger sensor may include at least one optical dispersion sensing pixel on an integrated circuit substrate for sensing dispersed light 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 dispersed light from the user'"'"'s finger. The sensor may also include a processor connected to the at least one optical dispersion sensing pixel and the at least one other finger biometric characteristic sensor.
