Foursquare Can Now Unlock Your Front Door

A pair of Brooklyn developers, Erin Sparling and Nicholas Hall, no longer need keys to get into their house. The boys from simply check in on Foursquare and, voila, the door unlocks.

We made it so if you check in to on Foursquare the door unlocks. Well, not you. Us. So you can’t steal our stuff. 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. Then we made a video about it to invite you to our New Years party.

The boys are throwing a NYE party and guests can check in for access.
