The only card that falls out for me is the CSP because it is thick and heavy.

Debit/CSP/SPG + ID + Gate key

I use 1 card per outward facing pockets (total 3 cards) and I slide my gate key behind my ID in the open ID slot.

I've had it for a while... I use it double folded, so it is about the size of just one credit card, as thick as my 5S.

I don't like the NEW version because it is too tall, I can not use it in the same pocket as a 5S for example; it becomes wider than the phone.
