I got a Samsung NFC lock recently so I could unlock my house with an NFC chip I had implanted in my hand about a year ago. Awesomeness of having my house key in my hand aside, the lock itself is very capable, and I'm quite happy with it as a standalone device. It comes with 5 NFC FOBs which will unlock the door, and each one is tied to a unique PIN combination. If you can't find your FOB, you can still use the PIN. It's been really effective at my house and for house guests.
