I'm new to craft shows so I have just accepted cash and local checks with name, address, phone number and DL #. So far, knock on wood, no bounced checks. I was interested in others' opinions on using Propay because I have had people ask if I take CCs. The craft shows I visit do not have internet connections (and I do not have a laptop), so that is out. I have a cell phone, but the booth gets crazy at times so I think it would be very difficult to call in each and every CC transaction. I guess as with everything, there is a risk involved in accepting CC's without being able to verify them until you get home. Something I am going to have to really think about.
