Recently, they have come up with an app that can end the credit card fumbling and taking out any cash. It's like Apple pay, except even more innovative. Google created this app called "Handsfree". So how it works happens like this: You walk into a restaurant or store and the technology in the place uses bluetooth, wifi sensors, and in store cameras connects your phone with you with the cash register while the security cameras matches with the selfie uploaded on the app for confirmation.
I found it interesting because it's the first time I've heard of paying money without touching a thing. No Credit cards or cash or wallets. Just a cell phone with this app available. Someday it'll only be like that. You can just walk in a mcdonalds and make your order while all of that is going on. That is why I found it interesting.
