Passbook
Using this app you will manage all the passes or loyalty cards, Apple's new
Passbook is to your rescue. With Passbook, you can store your boarding passes,
movie tickets, retail coupons, loyalty cards, and more in one place. Using this
app, you will be able to scan your iPhone or iPod touch to check in for a
flight, get into a movie, and redeem a coupon. Apart from all this, Passbook
will tell you when your coupons are expiring or balance left on your cards.
Once
these things are entered into Passbook, they become intelligent and interactive.
For instance, your Starbucks card will tell you your remaining balance, your
store card will present you with the latest offers, and your boarding pass will
instantly update and provide you with a notification when there are changes to
your flight.
