How to Select a Payment Processor

Other services offered by payment processors can include retail-transaction processing and check-by-phone processing.

Gateways

The alternative to using one of these payment processors directly is to use a gateway solution, a separate application or service bureau that formats, processes and tracks your transactions before sending them to one or more of the major payment-processing services. Fees per transaction processed may be more, but overall costs to acquire and maintain these solutions may be lower for smaller catalogers.
