What does NFC add to smartphones?

I'm seeing a lot of new smartphones have "NFC", but what does it actually do? Is it like Bluetooth?

Yes, in essence it is something "like bluetooth" - a filetransfer protocol to exchange a bit of info in a flash.

Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi.[1] Communication is also possible between an NFC device and an unpowered NFC chip, called a "tag".

It's like a faster, shorter range version of Bluetooth.
