Instead of waiting in a long line for a beer, users of Robokeg can simply swipe their wristband to get a pint from the automated bartender. Robokeg is a beer keg that acts as a bartender by recommending drinks, automatically charging users and smoothly dispensing brews.
To use Robokeg, all you have to do is load up your credit card and driver licence before entering the venue. When you're ready for a beer, you can tap your wristband on a NFC reader and get a drink poured for you. Robokeg then charges your credit card so that you don't have to worry about taking out your wallet.
In addition to being amazingly convenient, Robokeg is also integrated with social media. Users can automatically tweet what they're drinking after ordering a beer.
