If rumors that Apple is adding an RFID reader to the iPhone are true, it’s huge!
An RFID reader would turn the iPhone into an e-wallet — allowing you to pay for everything, from a cup of coffee to a subway ride. It could also turn the iPhone into an ID card, a security access system and an electronic ticketing device.
It’s could also function as an easy and secure online shopping system that doesn’t require you to enter your credit card number.
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.
Imagine if such a system was enabled on your iPhone. It would supplant your wallet — if enough retailers adopted the system, of course.
