Re-posting from the Arts and Craft threads in case anyone here has experience of this 
I have a tiny Etsy storefront where I’ve been selling handmade items for a few months, and I now have an opportunity to sell at an in person ‘pop up shop’ for a day
I have absolutely no experience of doing craft fairs or anything like that (as a seller) and wondered if anyone with a bit more knowledge could recommend what they use for taking card payments?
Thank you for any advice!
