Finger print reader


The other day my son brought back this 'finger print reader.'

Using a computer, we need a password or a code.
But this reader can save the trouble of typing the password.
Putting our forefinger on the red place, a computer reads the finger mark.
Once we register them, we don't have to type a code or a password.
We have only to put our finger on the red place.

This is a very useful thing!
