Hello, payment processors are financial institutions that work in the background to provide all the payment processing services used by an online merchant. These companies usually have partnerships with other companies that deal directly with consumers or merchants. The payment processor receives the transaction information from the payment gateway, validates it, executes it, and then transfers the funds to the trading account. It also notifies the payment gateway if the transaction was successful. Currently at https://payadmit.com/ you can read more information about the payment processor.
