Abstract:
A finger biometric sensor may include a substrate and an array of magnetic field finger biometric sensing pixels carried by the substrate. The finger biometric sensor may also include processing circuitry coupled to the array of magnetic field finger biometric sensing pixels and capable of generating a magnetic field extending into a finger positioned adjacent the array of magnetic field finger biometric sensing pixels to cause eddy currents in the finger. The processing circuitry may also be capable of sensing a counter magnetic field caused by the eddy currents representative of at least one finger biometric characteristic.
