APPARATUS AND METHOD FOR A BIOMETRIC SENSOR IN A HANDHELD MOBILE WIRELESS COMMUNICATION DEVICE

摘要

A smart phone device has a display screen overlaid by a touch screen and a processor and a memory in the device hosting functions to perform display and touch functions. A logic executing in the processor in the device programmed to use a part of the touch screen as a biometric sensor. The logic sets aside a space on the touch screen for that specific space to function as the biometric sensor. The biometric sensor configured to use and uses either a finger of the hand or a thumb and thus captures either a fingerprint or a separate and distinct thumbprint, where a fingerprint and a thumbprint are different biometric samples.
