The Carl's Jr. and Hardee's QSR chains have launched a GPS-enabled loyalty program that rewards users for checking in at the restaurants' locations across the U.S. The Happy Star Rewards app,
available for iPhone and Android smartphones, is the first within the fast-food industry to combine location-based check-in technology and rewards, according to parent CKE Restaurants, Inc. The Happy
Star Rewards app can be used to cross-post users' location check-ins on Facebook, Twitter and Foursquare.
