8. Credit Card and Biometrics as Software

The business world is also going to benefit from mobile innovation. Soon credit cards will become software. You will walk into a store and to pay, you simply choose a credit card button. The iPhone will communicate securely with the cash register in the store, via Blue Tooth or Wi-Fi. The safety of the transaction will be ensured via biometrics. For example, a clerk in the store might ask you to place a randomly selected finger onto the screen of your iPhone to verify that the phone belongs to you (assuming that all phones are securely initiated in the store and may not be reset).

Lots of very exciting stuff and, of course, 12 more reasons for getting yourself an iPhone…..!
