Nursery our son goes to have just decided to implement this. Apparently anyone who picks DS up will have finger prints scanned, then when we go to pick him up, the machine by the door scans your finger and lets you in (or not!).
I can see the advantage - at the moment you press the buzzer, and at busy times i'm sure they're constantly going to let people in, when should be looking after kids, and also we get let in quicker, v good for morning rush!
It's just i've never come across it before. Does anyone else have this?
Thanks!
