Payment Processors

Payment processors connect with acquirers. Before you can accept payments, you must register with

a payment processor

.

An acquirer might require you to use a payment processor with an existing relationship with the acquirer.

Your payment processor

assigns one or more merchant IDs (MIDs) to your business. These unique codes identify your business during payment transactions.

This table lists the processors and corresponding card types that are supported for payment services.

Only the card types explicitly listed here are supported.
