After spending most of today not being able to accept credit cards, Wash Card has ordered a terminal controller. Washcard had us switch the controller at another pay station to see if it was bad and it worked fine; put it back in the other pay station and it doesn’t work. So I now have two pay stations that won’t accept credit cards. Yes, we replaced the credit card acceptors. Wash Card technical support closes at 5:00. I’ve all but given up on being able to accept credit cards for now but am hoping someone on this forum can give me an idea of what else to try.
