Palm Recognition Devices identifies employees with their Palm Vein Structure. As an employee identifies himself on a Palm Recognition device, the device captures the palm vein structure of the employee and compares it with the previously registered palm vein templates already stored in it’s database. If the device makes a successful match, it notifies the employee and also records the time of the event. If connected to an access control system, the Palm Recognition device opens the door lock for the employee to pass.
