cardONE has been such a pleasure to work with. As a dentist, credit card processing is not my area of expertise; however, it is a necessary aspect of running a business.Lauren at cardONE set up our office with two wireless credit card terminals, and the entire process was seamless. We love the flexibility and functionality these terminals have given us, and we highly recommend the services that cardONE provides.

Ware Jewelers

For years, cardOne has been an outstanding partner for our business. Their service is personal, responsive, and reliable.Over the past year in particular, they helped us transition to Clover, which has allowed us to email payment links directly to our customers and streamline how we process credit cards. That upgrade alone has improved our customer experience and internal efficiency.Any time we have had a question or an issue, Lauren and Angela respond quickly. I am never left waiting or wondering who to call. They are accessible, knowledgeable, and proactive.We recently invested in a new POS software system, and before moving forward, I made certain we could continue working with cardOne. That is how important they are to our operation. I trust them completely and highly recommend cardOne to any business looking for a dependable credit card processing partner.
