Subject: Paying for groceries
I recently came across a device that would help making checking out at the grocery store easier. Its a small device that you would wear around your wrist like a bracelet. It is linked to your phone and you would be able to put an amount of currency on it via your phone. When you get to the register to check out you just hold the device next to a paying terminal and it makes a transaction. No more having to pull out your wallet. What do you think of this device
