Payment Hub Architecture

What You Can Do After This Chapter

Learning objective. Learner designs a payment hub architecture, explaining intake, validation, routing, transformation, screening, and settlement modules, and maps a payment through each module. Learner applies this skill in realistic banking scenarios, with clear examples and correct terminology throughout.

Practical assessment. Learner designs a payment hub for a bank processing 100,000 payments per day, drawing the module diagram and naming the function, inputs, and outputs of each module. Learner then maps a 40,000 euro SEPA payment and a 60,000 dollar SWIFT payment through the hub, showing the routing decision, transformation, and screening step for each. Learner submits all work with sources, calculations, and assumptions stated clearly, and reviews the result against the chapter checklist before submission.

Expected deliverables.

• Payment hub module diagram
• Module function and interface table
• Payment routing map for two payments
• Hub failure and fallback design note

Completion criterion. Learner names every core module correctly, maps both payments through the right modules, and explains the routing decision for each payment. Completion is judged on accuracy, completeness, and clear written explanation throughout.
