The best fingers for fingerprint lock enrollment are the index or middle fingers.
Why Index and Middle Fingers?
According to the reference provided, you should prioritize enrolling your two index fingers or two middle fingers for fingerprint locks. The reasons are:
-
Ease of Positioning: These fingers are naturally easier to position correctly on fingerprint sensors, which leads to higher quality fingerprint reads.
-
Reliability: Consistent positioning means more reliable unlocking, and fewer errors.
Fingers to Avoid
The reference specifically suggests avoiding the use of:
- Thumb: The thumb can be difficult to position correctly on the sensor.
- Ring Finger: The ring finger's position and angle can lead to poor reads.
- Little Finger: Similar to the thumb and ring finger, the little finger can be hard to position consistently and reliably.
Recommended Enrollment Strategy
- Enroll Two: The recommendation to enroll two of the best finger types enhances reliability. You always have a backup finger available if the sensor has issues with one.
- Use Index Fingers: Image 3 and 6 in the reference suggest the index fingers are a prime choice.
- Use Middle Fingers: Image 2 and 7 suggest that the middle finger are also a great alternative.
