In this chapter, we have seen the essentials of online credit card processing and how a purchase is achieved as a result of complicated checks. Hopefully, we won't need to enter the details of credit card networks or merchant accounts. We have seen that payment gateways (with merchant account) like PayPal, Authorize.net
can easily provide such solutions. We have seen how to enable PayPal and other basic payment methods for OpenCart.
