It is often very dark in basements or apartments, therefore it is quite difficult to find the keyholes or to insert the key into it. This is the reason why I design a key scanner. You can open the door by scanning the key. The difference between the fingerprint recognition door lock and the key scanner is that it will be very difficult, and not so hygienic to use the fingerprint recognition door lock if someone lives in an apartment with many public rooms, like laundry room or bike parking room etc..
