Wendy’s fast food chain is using QR codes on its takeout bags to promote their late night menu and boost consumer engagement. The campaign encourages the consumer to check in to store locations by rewarding them with prizes. Users scan the QR code with their mobile device and are able to find the closest Wendy’s store. The user must check in to the Wendy’s in order to have a chance at winning a prize.
