I don't make pipes, but I use my bank, Regions as my POS with a card swiper, especially at festivals. I was at an art show this weekend and three weeks before, i tested my swiper, as I always do, running my wife's card for $.010. It worked. I got to the art show, and the swiper no longer worked. I called my bank, and they had noticed suspicious activity, and due to covid, they shut down my account. They cited that it could be operational in three weeks. UGGGG!!!
I could only accept cash or use my paypal, sending invoices... needless to say I had people turning away at the close of the deal.
( I barely made my booth fee back.
I suggest contacting your bank about setting up a POS system. You can either use the swiper or type in CC info. Sometimes you can get a deal on the % if you've been a long time customer.
