Apple has filed a very interesting patent for a travel app called iTravel that books flights, hotels and car reservations. But the most interesting part is how it uses a radio chip to check you in at the airport, whisk you through security and allows you to wireless board your flight.
The iTravel app uses Near Field Communications, a short-range wireless technology that is starting to become widely used in cell phones for mobile ticketing, payment and electronic keys, especially in countries like Japan.
Apple is rumored to be adding NFC chipset to the next iPhone. If so, it could turn the iPhone into an electronic wallet, allowing you to for everything, from a cup of coffee to a subway ride. Your iPhone could unlock your car, pick up e-coupons at the local mall, and pay for all your supermarket groceries just by laying it on top of the checkout.
