Frequently Asked Questions
What is payment infrastructure?
Payment infrastructure is the complete ecosystem of networks, institutions, protocols, and standards that enables money to move between parties. It includes card networks (Visa, Mastercard), acquiring and issuing banks, payment processors, clearing systems (ACH, SEPA), real-time payment rails (FedNow, SEPA Instant), and messaging standards like ISO 20022. Every electronic payment you make activates multiple layers of this infrastructure simultaneously.
How does ISO 20022 affect my business?
ISO 20022 becomes mandatory on SWIFT for cross-border payments after November 2025. If your ERP generates MT103/MT101 payment files, they need to be converted to ISO 20022 pain.001 format. Your bank statement reconciliation must also support camt.053/054 format. Businesses using Logo ERP, SAP, or Oracle should check with their vendors about ISO 20022 upgrade timelines now.
What is the difference between a payment gateway and a payment processor?
A payment gateway is the front-end technology that captures, encrypts, and transmits card data from checkout to the payment network β it also handles 3D Secure authentication. A payment processor manages the back-end clearing and settlement of the transaction through the card network and acquiring bank. Modern integrated providers like Stripe and Adyen combine both functions, but enterprise merchants may use separate best-in-class providers for each layer.
