This New Year's Eve, some partygoers will find themselves checking in on Foursquare should they wish to gain entry to a house party in Brooklyn. No, this is not some checkin campaign cooked up by a brand, but instead the product of two New York technophiles who have jimmy-rigged their front door to unlock with each Foursquare checkin.

Erin Sparling and Nicholas Hall created the check-in-to-get-in door for their own individual usage, but will be repurposing their creation for broader use on New Year's Eve. The duo also produced a video invitation for "The Location of New Years" occasion, as seen above.

As for the technology behind the gimmick, the pair writes, "We did it with Foursquare's Alpha 2.0 API, a local push notification service, an industrial web-enabled relay device, some speaker wire, and knowing about electricity," in a blurb on the Apartm.net website.

Given the ingenuity behind the video invite and the unlocking mechanism, this soirée should make for a very geek chic way to ring in the new year.
