I understand. Without trying the app myself, I was interested in how organised the cards are. Hmm... I'll bet the app doesn't use location services to determine you are at a Starbucks, or a train station, and bring the relevant cards to the front All it would have to do is store the location you were at when you created the card, and that is where you are most likely to need that card again. Am I going to make a million dollars yet?
