Activates the Encrypting PIN Pad (EPP). It manages the number of allowed digits, masking character display (asterisks), and encryption keys.
Second, the guide addresses state management. In a legacy NDC environment, the host tracks the state of the transaction (e.g., "waiting for PIN," "selecting account"). In Aptra Advance, some of this logic can be offloaded to the terminal. The guide instructs developers on how to manage these states locally, reducing network latency and improving the customer experience.
I wanted to share/flag the for anyone looking to streamline their workflow or troubleshoot complex scripting issues. Whether you are migrating legacy OS/2 applications or building new transaction flows, this guide remains the gold standard for understanding the architecture. aptra advance ndc developer-s guide

Screens define the visual layout presented to the cardholder. Advance NDC supports legacy text-based screens, basic graphical assets, and modernized HTML5 web extensions. Screens are mapped directly to specific state IDs. Financial Institution Tables (FIT) Activates the Encrypting PIN Pad (EPP)

While direct access to NCR's official documentation is restricted, the following resources are valuable for developers:
I can’t republish copyrighted Amadeus content directly. But if you have a (e.g., error handling, schema mismatch, workflow), I can help explain or reconstruct the logic.
Developers use specific screen IDs to define layout, text, and interactive elements.
