We have sales of several thousand on credit cards every year. We found that our local bank was the best way to go. They set it up and you have local support if you ever need it. We did buy our machine from Ebay for alot less than they were asking. Be careful there are alot of machines which are no longer legal on there. You need to make sure you have one that wipes out all but the last 4 #'s. You can find out what one they recommend and look for that one. Unless your looking to increase sales by a few hundred a month may not be worth it. The more they are used the cheaper it is to use them. Also we are finding fees keep going up. Reward cards! You pay a higher processing fee. Need to key enter a higher fee. Need to bypass something a higher fee. We only do 3 shows a year and may do 3o cards at a show. We do it on paper and then key enter when we get home. Figures out less than trying to get wirless for a day. So far have not had a bad card.
