Is anyone using this system (or any other) for selling cash and carry items at booths/fairs? I'm probably going to be investing but looking for the thoughts of those with experience. I have a booth at our local youth fair (BIG event) and after 15 years as a consultant have accumulated just a couple of extra things. I won't take checks at the fair (unless it is a known past host/good customer) and not everyone has cash. I believe this is the way to go but don't have any experience with it. This is NOT for current product sales!
