I own a couple washes and have been accepting credit cards at my main wash for several years. I currently have cryptopay, and ethwah valley, as well as the hamilton ACW5 credit card readers. I want to add a credit card reader to my ACW5 at my second wash. My first thought is cryptopay but it seems like out dated technology to me. This is a low volume wash so I don't want to buy a dan or anything like that. Is there anything available that will take chip cards, tap, swipe, etc that will work on the hamilton ACW? I wonder if cryptopay is working on any new technology?
