Easy installation and use, great for families with children

I was just a little confused about the seemingly difficult assignment of the fingerprints in the other reviews. I can not confirm it but. Our youngest children 6 years and even with them it took no longer than 1 minute until the scanner accepts the fingerprints. For us it was important because we wanted to give the children a series of numbers. Now you can automatically get into the apartment, without which I always have to play door opener. The installation took only 5 minutes and is less technically skilled people possible. The door opener is functioning properly.
