Do you find splitting the bill problematic when you’re paying with a credit card? After all, you have to figure out who ate what, and the person who pays via credit card will end up with a whole wad of cash. The solution is that concept device – Piece of Cake. You’ll be able to choose the items that you ordered, and from there, you can just swipe your card into the “cake”, and you’ll pay for your portion. Going Dutch probably couldn’t get any easier than that.
