The Illuminati Convenience Store

Would you give your handprint over to a payment service so that you could go around town shopping with just your palm? There's a convenience store at the Lotte World Tower on the 31st floor where you can experience the corner shop of the future.

It's called 7-11 Signature. the store has no employees and you don't even need to carry your wallet to purchase anything from sour apple vodka to ramen. You do, however, need to scan your registered handprint to enter the store and you need it once again to pay. It's creepy but futuristic at the same time. Would you do it?
