Assembly and Acquisition Notes
1. This palmprint collector is the whole machine, pay attention to the voltage stable input can be.
2. Palmprint acquisition: center the palm of the hand, top the end of the finger on the top of the acquisition panel, and place the palm surface flat on the acquisition panel.
3. Rolling finger acquisition: in the bottom third of the acquisition panel, roll the finger to collect.
4. Four-finger acquisition: place the corresponding fingers according to the prompts, do not tilt the fingers on the acquisition panel, and do not separate the fingers too much.
