Hi all, I'm finally deciding to take the plunge and get some kind of card reader / payment system, but I only do a couple of craft fairs a year at most, so it needs to be something low investment. I have a smart phone with Android....but then I know for a fact that one of the fairs that I'm doing this year is in an area with poor phone signal coverage. (In the past I did Bovey Contemporary Craft fair, which was problem-free because they have a central card payment system that takes payments on your behalf, for a fee of course).
