Oh, goody! The automatic brass key cutting machines in many store lobbies are being upgraded to duplicate RFID key fobs and cards! How're your security and HR teams going to like it to discover employees can make their own backup spare access cards?
I've seen these machines (at least the key making ones) near the entrance/exit of local WalMarts.
On cloning key cards, etc. I've sat in on presentations on those who do physical pen testing, and what they had to do to capture info from key cards to clone them. Since they don't steal them, but get close enough to copy the info, while its not quite the same, this would require getting a hold of the actual fob or card to create a copy.
