When you put your palm over the palm vein sensor, it has two functions as follows:
Function ;PVG102-B can send unlock signal to the lock, then the door can be opened .
Principle:
When nearinfrared scan palm, palm vein has a little refection, then form palm vein lines image. In a word, by checking reflection near-infrared strong or week, knows palm vein position. It means we should put our palm in a right gesture, then can unlock and time attendance successfully.
It’s the most advanced biometric access control and time attendance than eyes ,face ,finger and so on. In the world , few companies master this high end technology.
Safety:
1. Living body detecting function.
It means if our palm is cut, since the palm is separated with body, and the blood can’t move. Then it is impossible to be recognition, can’t open the door and time attendance then.
The purpose of this function avoid criminals cutting victims the palm to open the door.
2. Palm vein is 3mm below skin and it’s body’s inside information, so it is difficult to be counterfeited. So far there is no case of palm vein being copied.
Reliablity:
Palm vein is much thicker, so it can’t be influenced by environment, such as temperature.
Homony:
Contactless. We put our palm 5cm over the sensor and then the palm veins can be captured without contacting the palm, thus people will no rejection mood.
High accuracy:
False rejection rate: Less 0.01%
False accept rate: Less 0.00008%
