With NFC baked into Symbian Belle (and a few Anna builds!), the number of applications with NFC capability keeps on growing. The latest addition to the number is Foursquare, as detailed in the NFC blog post quoted below. You can now just walk up to a Foursquare check-in poster at an event, tap your phone to it, even if the application isn't already running, and bang, you're checked in. 

From the blog post:

The latest addition to the growing number of NFC enabled apps like Angry Birds Magic, Poken, Bounce and Asphalt5 is Foursquare.

With the newest version of the application you can use your NFC enabled phone to check-in automatically by just tapping and NFC enabled/tagged poster. No more tedious steps of launching an application waiting for location fix, connecting etc... With NFC this is all done with a simple tap.

Furthermore, the developer made it even easier for the user to check-in - without the need to have the app running - just tap and the app starts automatically and checks you in. Pretty awesome and again demonstrating the convenience of NFC! In a separate post Andreas explains how as a developer you can implement application autostart . 

Foursquare with NFC support is available in the Nokia Store for Symbian NFC enabled phones (download Symbian version here, N9 support coming soon) . And the best thing about it is that it is not a separate application just for NFC sake. Developers simply added the support for NFC to the existing application version!

Symbian phones with NFC currently number six: the Nokia C7/Oro/Astound, plus the 700/701/603, and all future Nokia smartphones going forwards will also have NFC baked in.
