CardX
CardX is a payment processing company based in Chicago, acquired and controlled by Stax. It provides merchant services to businesses and agencies in the government and education sectors; and is famous for its 0% surcharge cost to businesses accepting credit card payments. Having served over 5,000 customers and currently having more than 200 entities using its technology, CardX is pretty much a leading newcomer in the merchant service industry. However, with its clear-cut pricing structure and intuitive interface design, this merchant account provider is also known for making payment processing hitch-free for businesses.
