All currently supported credit card processors are supported in the eCommerce store, with the exception of Bambora. Contact customer support for more details and for available options. You will enable credit card payments within the Payment Methods functions. 

Note: No configuration should be done here because the Store automatically pulls the credit card configuration that has been setup for your events and online bill pay that was done with assistance from ChamberMaster/MemberZone Customer Support. Contact customer support with questions.
