I typically carry a fair number of cards both for the office and personal use together with insurance and other cards for ID and club/gym memberships so I am pleased to report that this case is an ideal solution.
The case has a window section for drivers license etc and I can fit two/three cards in this section. On the other side of the case there is a thin(ish) slot that can hold four or five cards but the more cards in this section the more it impedes on the biggest section that can hold probably 15 or more cards. Finally there is a pocket on the back of the case that is really just a slit in the leather. The leather on the three sides of the biggest section is very flexible which is the reason the case can hold so many cards in this section. The more cards carried the more that the flip over part with the window section tends to bow outwards but I don't really find it a problem.

I rarely carry a wallet in a coat pocket always in my front pocket - I was told this is the safest area by a professional thief once! When wearing a suit/sports coat I tend to carry a lot fewer cards and use a differnet holder. The Swiss Bags Card Wallet could hold folded banknotes it you wanted to, I guess, but they'd have to be fairly few in number depending on how many cards are in the Wallet.

I have an aluminum Ogon wallet but it could not hold many cards without splitting and it is hard to find leather cases that hold large numbers of cards and as I don't have RFID cards yet and even if I did a piece of foil in the case would help

The case has a fairly disceet Swiss flag button in one corner - I daresay it might look like a Swiss Army product possibly. The leather is not bad but you would not mistake it for a LV/Hermes item. If I had a complaint it is the leather around the big section which is fairly thin so I am not sure how durable it will be. But, I think it was designed to be flexible not stiff and unyielding so the number of cards carried could vary. It acts like a concertina and squishes flatter if you have fewer cards in this bigger section. I tend to carry the three cards I use most in the smaller inside pocket and it is easy to pick the one I want to use without pulling them all out. I keep the less used ones in the larger section

In some ways I wish it were better quality as I would not have minded paying $80 for it never mind $8 but I don't want to mislead as it really doesn't look much different to ones I've seen costing $40 or $50. I tend not to stand holding a wallet in full view so I'm not too worried about the quality side - it looks good enough and anyway for the most part is hidden in the hand. I will buy a couple more to act as spares as these sorts of card wallets are sometimes hard to find and it is downright cheap.
