Fintech Issuer Payment Processor Job Halal or haram

I am working in card payment Fintech that provides software for transaction processing. The company has Clients who provide prepaid, debit and credit card to their end users. Prepaid card client constitute majority of clients; but organization is trying to expand on credit client and also going into Digital Banking as well. The clients of the organization include fintechs (like payoneer, square) and banks. I work as Manager Business Intelligence that deals with designing reporting and analytics solutions for all types of clients; and company makes earning from these as well. But majority earning is from transaction processing. Is my job halal or haram?
