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).
