Abstract: An electronic device may include a finger biometric sensor and a processor and a memory coupled thereto. The processor is capable of performing a first matching to determine a first matching score of sensed finger biometric data against finger biometric template data stored in the memory, and indicating a match and updating the finger biometric template data when the first matching score exceeds a first threshold. The processor is also capable of performing a second matching of the sensed finger biometric data against the stored finger biometric template data to determine a second matching score when the first matching score does not exceed the first threshold and updating the finger biometric template data stored in the memory when the second matching score is above a second threshold. The second matching is slower but more accurate than the first matching.
