Never take Checks! For me, only about 1 in 10 are any good. So I stopped taking them years ago.
For CC, I use my iphone! There are numerous apps now that you can get that you can process CC with. I love it.
In the past 6 weeks, I've done thousands of dollars with of transactions with it. Heck, I've had customers buy something just so they could use the iphone!

But you are correct, most show venues do not have phone lines or Wi Fi to use computers or POS (point of sale terminals). I believe cell phone apps are the way to go.

Good Luck.
