NFC - What do you use if for?

Many users are up in arms that the iPhone 5 doesn't have NFC. But as a HTC One S user, I've never missed not having it. It seems to me that mobile payments are way too immature, and I've seen people use android beam for contacts - I'd rather put it in manually.

So I'm asking you. What do you actually use NFC for?

Note - I would add a poll, but I'm not sure it's enabled. If someone knows how let me know!
