AllThingsD gets up close and personal with Passbook -- a new feature of Apple’s latest mobile operating system, iOS 6, which hopes to make physical sports tickets, gift cards and boarding
passes a thing of the past. After recognizing a users’ proximity to a physical event, Passbook will alert them to that fact, and then automatically scan them in. An earlier adopter of the
technology, Major League Baseball is currently testing Passbook with four teams, including The San Francisco Giants, New York Mets, Boston Red Sox and Kansas City Royals.
