The φ² project at Stockholm University is actively working with different procedures for physical Foursquare checkins.φ² Scanner for Android is the first result of their works and simplifies the checking process with 2D bar codes that users can scan to locate their venue in Foursquare.
The idea is similar to what Google is doing with the QR code window decals for Place Page business owners, but it’s specific to Foursquare and requires that users download and install Foursquare’s Android app.
Working procedure:Users or venue owners can generate a printable 2D bar code — using the venue address or Foursquare ID — and stick it on the venue in question.Visitors can then use the Android application to snap a photo and scan the code. The scan automatically pulls up the venue in question in the Android Foursquare app for a faster checking.
