Claim:
1. A method for authorizing the use of a biometric card, comprising: sensing a biometric identification reading associated with skin; generating a first photocurrent signal based on reflective scattering of a first laser light generated by a first laser, generating a second photocurrent signal based on reflective scattering of a second laser light emitted by a second laser, converting the first photocurrent signal to a first waveform and converting the second photocurrent signal to a second waveform, wherein one of the first and second lasers is an infrared (IR) laser; determining a relative absorption of the first and second waveforms; and authorizing use of the card in response to an authentication of the sensed biometric identification reading and the relative absorption.
