Abstract:
1. A method for authorizing the use of a biometric card, comprising: powering up the card; sensing a fingerprint of the finger; authenticating the sensed fingerprint information; sensing a finger on an SpO powering on a red laser and a photodetector; performing analog-to-digital conversion on reflective light scattering from the red laser received by the photodetector; powering off the red laser; powering on an infrared (IR) laser of the card; performing analog-to-digital conversion on reflective light scattering from the IR laser received by the photodetector; powering off the IR laser and the photodetector; estimating an SpO authorizing the use of the card based on the fingerprint authentication and the SpO
