I always thought it would be cool to have a fake hand scanner hanging on the wall by a door. It would give your place a real Bond villain vibe. It could feature some built-in functionality like a light switch or thermostat, but more or less it would just be for show.

make a smaller “thumbprint scanner” version and it could be mounted outside as a doorbell!
What about as a lightswitch?
That was mentioned in the post.
I too was looking for a fake or decorative hand scanner to mount next to the entrance door of my rv / transit bus conversion. It would be cool! Especially if it triggerd the air door to open 🙂
I really wish it would work for a real door or i would buy it😔
how can i buy this? my son says this is all he wants for Christmas is it possible to buy this?
