[Q] Question about NFC phone to PC topic

So have a tmo note 3 and a dell xps 12. Both have nfc and can detect when they get close to each other.... this is where my knowledge ends. I have googled with no luck so would appreciate more than "just search". Giving me keywords to search for is a good option too.

So what I want to happen is phone and pc unlocks when I bring them together. And possibly connect airdroid or something similar between them so I can use my phones features on my pc without plugging in anything. If anyone wants to just point me in the direction of some cool programs that use nfc for windows that would be great also.
