Advance NDC relies on a host-controlled architecture. The ATM itself does not hold business logic or make transactional decisions. Instead, it behaves as a state machine that executes specific commands sent by the host.

It is highly recommended to use the APTRA terminal simulator to test transaction flows without needing physical ATM hardware.

NCR provides specialized tools within the software development kit (SDK) to streamline development: Advance NDC relies on a host-controlled architecture
APTRA communicates with physical hardware—such as card readers, cash dispensers, and receipt printers—using the interface. This standardized layer allows Advance NDC to control diverse hardware modules while presenting a uniform interface to the developer. 2. Core Concepts: States, Screens, and Financial Messages
Standard Advance NDC configurations handle typical cash withdrawals and balance inquiries perfectly. However, implementing unique features like cardless transactions, dynamic currency conversion (DCC), or custom marketing graphics requires explicit developer intervention.

For developers maintaining older APTRA Advance systems, the guide dedicates Chapter 11 to migration strategies.
is an software application designed for NCR self-service terminals that facilitates communication between the ATM and the host banking network. It is the evolution of traditional NDC+ (NCR Direct Connect Plus) protocols, designed to run on top of Windows-based operating systems. Why Choose Advance NDC?
For early testing without live airline credentials, the guide includes a mock NDC server (Docker image ncr/aptra-ndc-mock:latest ). It simulates 85% of real airline behaviors, including scheduled delays and random price changes.
