MasterCard has partnered with Facebook Places to launch a campaign involving the original Yankee Stadium seats. Twenty seats have been scattered throughout New York City at places, including the New York Stock Exchange, for fans to locate and scan a QR code. The QR code checks the fan into Facebook Places where they have a chance to win VIP tickets to a 2011 Yankee game in MasterCard’s exclusive “Batter’s Eye Café”. This campaign is the launch of the MasterCard Priceless Cities program, which aims to rival the recent partnership of American Express and Foursquare. For more information, please visit Mashable.
