Do you have a card swiper / chip reader so you can process payments directly?
Yes. I've been using PayPal Here for a few years with great success. I'm just looking to improve the process of collecting of order information.
Wouldn't it be better to have the customer enter their info with their own phones instead of using your ipad? I assume you get the orders at the same time more or less.
Possibly. And yes, orders and payment happen at the same time. At these events orders are about 60% credit and 40% cash transactions.
