This app concept for iPhone and Android would let you take control of your tab and pay securely with your phone. Stop dealing with the hassle of waiting, or a working it out with a pile of cards when you split your tab with friends.

Personally, I am quite pleased to have one less item in my pockets when going out! All the clutter such as wallet, cards, ID soon might be completely replaced by wearable mobiles likeĀ this one.
