Interactive Infrastructure Simulation

Tracing the structure of a card payment authorization.

A Savion-styled version of the original explorer. Same flow logic, same step-by-step simulation, same approval or decline path — rebuilt to match the visual language of the new site.

This page is designed as a practical companion to the broader Savion framework on payment infrastructure, routing, and transaction design.

Focus Authorization

The tool isolates the authorization leg of a card payment before final funds movement takes place.

Logic Balance-based

This simplified version decides approval or decline entirely on available cardholder funds.

Use case Infrastructure education

Useful for showing the role of each intermediary inside a standard card-rail transaction flow.

Simulatore semplificato: l'autorizzazione è basata esclusivamente sul saldo disponibile. Nel mondo reale entrano in gioco anche antifrode, autenticazione forte, scoring di rischio, controlli issuer e logiche di routing.

Explore the structure behind the transaction.
