Just when you thought your smart phone couldn't come more in handy.
Now you can use it on your daily coffee run to Starbucks and leave your cash at home.
Starbucks is partnering with Square, a start-up that allows shoppers to pay for items with their smart-phones.
Starting this fall, at seven thousand Starbucks locations, you can pay with a simple scan of a barcode on the app.
In the future, you'll be able to tell the cashier yo
ur name and like magic, it's paid for.
