Wednesday, Apple declared the recently made updates in the iO6 mobile operating system. StubHUb, Major League Baseball and Fandango have shown their keen interest in the Apple's Passbook app, included in the iO6.

All the three suggested that the app is simply a practical holder, which can help store the e-tickets or any other boarding passes or coupons, which could help boost the existence of paperless ticketing.

Wednesday night, MLB officials showcased regarding the Passbook tickets at AT&T Park. Further, it has been reported that San Francisco Giants, the New York Mets, Kansas City Royals and a few others will be examining the app for some of the home games, although, they will be continuing with their regular season.

MLB asserted that if the test comes out with positive results, then it will be making the app available to all the 30 clubs by 2013. Matthew Gould, Vice President of Corporate Communications for MLB Advanced Media, said, "He could envision a day when the majority of fans use digital tickets. Just look at the airline. We want to get there and this is a great step forward".

The Passbook app has been supported by iPhone and iPod touch, but it has not been included in the iPad. Fans booking their tickets will get an e-mail confirmation, which can be stored in the app.
