How does it work?

On the venue side

• install the CheckMeIn iPad app on an iPad 2 (with a front facing camera),
• connect the device to a WiFi,
• configure the venue (at first launch).

On the end-user side

• connect to foursquare,
• display your foursquare profile pic on your iPhone screen,
• scan the profile pic with the iPad app (put your iPhone in front of the camera).
