Payment Processors

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

a payment processor

.

An acquirer may 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.
