We've already seen local businesses take the plunge, offering up special location-based deals that Foursquare automatically serves up to users as they check-in, but now BART is getting in on the action to encourage more public transit use.
Regular BART commuters will now be able to unlock a BART-themed badge, and also become eligible for $25 in promotional tickets that will be awarded randomly to Foursquare users who check-in at stations during the months of November, December, and January.
From the official BART announcement of the deal, we also learned that this is just the beginning of the partnership. The transit agency is also looking for even more creative ways to tap into the location-based potential that Foursquare offers for promotions, and highlighting local businesses.
