Fumbling for your cards waste time and be a lot of trouble. So, just before you get to the event, transfer a batch of cards to an empty pocket. Then when someone asks for a card, all you have to do is reach in and whip one out. Less time, less hassle and much cooler than not being able to find your card case.

To make sure they don’t get mangled, don’t sit down too much between the pocket/card transfer and handing your cards out, especially if you keep them in your back pocket as I do.
