Palmprint Modality
Capture Your Palm
Your palm’s principal lines and texture map to melodic phrasing, harmonic intent, and rhythmic detail. Hold your palm flat with fingers spread, ~15 cm from the camera.
How to hold
Spread your fingers and align tips with the pegs — palm facing the camera, ~15 cm from the lens. Even light, no rings or sleeves over the wrist crease.
The shutter fires automatically once the detector sees a fully-open palm, well-centred, for 1.5 s.

Tips for best results

- —Remove rings, watches, or anything covering the palm
