Want a candy from the gumball machine but don't have a quarter? Not to worry, we're living the future now with the Paypal Vending Machine -- no coins required.

This new tech machine permits the use of smartphones to scan a QR code and make a Paypal payment. Incorporating social media, the vending machine tweets your payment with a confirmation display. So now you're not just making a simple purchase from the Paypal Vending Machine, but sharing it with the online community. How cool is that?
