I have tried to find a slim fold wallet that can hold: credit cards, medical cards, business cards, crap cards and money for a long time.  Wife says I am really picky.  This wallet solved all my problems without adding any bulk.  Place for your ID can hold - driver's license and probably 2 or 3 credit cards (I have the ID and debit card).  Card slots on the back with the elastic money can hold around 4 credit cards (I have three credit cards and 5 business cards in the top one and another 4 credit cards in the next slot).  The main slot holds a ton (10 cards total and more room if needed).  Well worth the money.
