foursquare has released the FFC badge. As suspected, you have to like the Fulham FC foursquare page and then check in to one of their matches while it is going on. Along with your new badge, you will receive the following message:
FFC is taking you home, to the place where you belong. Craven Cottage, by the River. Thanks for checking in @FulhamFC! You can now purchase our brand new Fulham & foursquare t-shirt & you might be rewarded if you wear it! http://ow.ly/hSV4o
The foursquare Fulham FC badge will be available starting tomorrow, Saturday, February 23rd. The badge’s design and exact unlock criteria are currently unclear. One can assume that you have to like the Fulham FC foursquare page and then check in to one of their matches to earn the badge.
I will be updating this post when more info about the badge and an image of it becomes available.
