A specific variety of payment gateway services provider, credit card processors are companies that handle transactions that are made via plastic. Typically a third party, credit card processors are usually exclusive to credit-based purchase methods, although more firms are expanding their services to bring added options and convenience to customers. Any business that wishes to sell products or services and accept credit cards as payment goes through a credit card processing company. Integrated payment middleware products already have affiliations with credit card processing entities, eliminating this step for business owners. Organizations that provide these services include BluePay, Chase, Elavon, TSYS, Worldpay among others. See Payment Processors.
