2. Near Field Communication
If you own an iPhone 5, you can just forget about using mobile payment systems that let you touch your device to a reader in order to conduct a transaction. Instead of MasterCard's Tap and Pay, you'll be using tap and pray as you rap your fingers on a table and hope that Apple provides NFC (Near Field Communication) support on the iPhone 6 in 2013.
With NFC support, the latest Android phones can not only send out payments, but also share photos, contacts, videos and more, just by tapping their backs together. Since Android 4.0 Ice Cream Sandwich, the OS has built-in NFC sharing software called Android Beam that any third party application can use for seamless sharing. Task management app Any.Do even lets you beam assignments to friends and family. I'm sure Apple will add this functionality just in time for iOS 8.
