Thousands of iBeacons will be placed in Major League Baseball ballparks next week, with MLB hoping to have 20 parks outfitted by Opening Day in late March. Boston, Milwaukee, San Diego, San Francisco, and the L.A. Dodgers will be among the teams with iBeacons installed in their stadiums, MacRumors reports. Each park should have about 100 iBeacons installed. It was reported last year that many MLB teams expressed interest in iBeacon, with the New York Mets already testing the technology. iBeacon will work with MLB’s At The Ballpark app. Though functionality will differ in each ballpark, it’s likely the app will use iBeacon to offer ballpark information, concessions coupons, and loyalty programs, among other features.
