Learning to drive by fingerprint is driving school. In order to ensure your study time, it is equivalent to attendance. Generally, you only need to press your index finger or middle finger to collect your fingerprint information. Because sometimes there is dust or broken skin on your finger, you need to press it in turn until it is put away ~

Taking a driver's license by fingerprint should be equivalent to roll call to prevent someone from replacing the candidates. Generally, only the index finger or middle finger is needed, as long as the information is collected.
