foursquare and the National Football League will celebrate Super Bowl Sunday with three special badges — one for Pittsburgh Steelers fans, which they can unlock by including “Go Steelers” in their check-ins; one for Green Bay Packers fans, acquired in similar fashion; and one for fans who actually attend Super Bowl XLV at Cowboys Stadium in Arlington, Texas.

Users of the location-based mobile app will also receive promotional codes entitling them to 20 percent discounts on select merchandise from NFLShop.
