Yeah, I'm going to be honest with you, this kind of freaks me out!
According to Delish, Amazon is currently testing a new technology called Orvill that would use a customer's HAND for payment at the grocery store. Apparently, it uses a camera to identify the shape and size of a person's hand and then charges the linked Amazon account.
So, I guess in the near future, you'll be able to go to Whole Foods, get your food, and then just hold up your hand and be on your way (the technology apparently works in less the 300 milliseconds.
What do you think, cool or creapy?
Also, what happens with identical twins???
