Baseball's beacon trials hint at Apple's location revolution

As we neared the threshold of the gates in front of the walkway to the home of the New York Mets, a message popped up on developer Chad Evans' space-gray iPhone 5S.
"Welcome to Citi Field."
After a few more paces, we encountered the famed Mets Home Run Apple in front of the stadium. Evans moved his iPhone 5S near a sign by the landmark, and a video popped up detailing its history.

MLB to use iOS 7's iBeacon for pointing out sights (and seats) in stadiums

Major League Baseball is becoming very iPhone-friendly: it gave iOS 6 users Passbook ticketing this season, and it's now planning a treat for iOS 7 users. A 2014 update to MLB's At the Ballpark app will use iOS 7's iBeacon feature to guide sports fans as they pass by low-power Bluetooth transmitters in the stadium. Enter the ballpark and you'll get seat directions; visit specific points and you may get coupons or highlight videos. Only the New York Mets are testing the feature at Citi Field, but the league believes that other teams are likely to follow suit.
