Nice try but no banana

Kudos to coin for being a front runner, but the simple truth is that it cannot be used as a replacement to all your cards because there are too many situations where you need the original card, therefore defeating the point of only having to carry 1 card. I hope the second version of this card with the smart chip fixes this.
