I Saw this one a TechCrunch blog and thought that this is extremely promising. http://www.walla.by/ From What I've read; basically its a physical card that is linked to all your other cards and based upon preferences and what not, when you swipe your card it will determine what card is best for rewards/points and send the information along to that card provider. This potentially could be AWESOME; one card multiple rewards. (5x Freedom + 2x SP + SPG) while just carrying one card. What do you guys think?
