I usually carry 5-6 cards with me and very little cash. This is very convenient and also blocks RFID. tried it on several machines and kept it on the machines. The external card is also well protected. Very happy with it. I have a feeling you can hold about 6 cards and the skin can stretch after that. The money clip is also good with a few bills. I'll update this post with my results after a few months of use.
