NCR APTRA Advance NDC (Network Delivery Control) reference manual is a technical guide for developers and system integrators who work with NCR's self-service terminal software. It details the messaging protocol and operation states used to communicate between an ATM and a central host. Core Content of the Manual The manual typically covers the following functional areas: NDC Messaging Protocol : Detailed specifications for message formats, including: Host-to-Terminal
But with great power comes great complexity. The is the bible for technicians and implementers. However, NCR releases updates to this documentation frequently to patch security vulnerabilities, support new hardware (like cassette designs or recycling units), and introduce new transaction types.
The NDC protocol relies heavily on "States." The manual explains how to map a specific Host State (a code sent by the bank's computer) to a specific Screen Number on the ATM. aptra advance ndc reference manual upd
Today, we are looking at how to tackle the process. Whether you are migrating from an older APTRA version or simply trying to decode the latest addendum, this guide will help you understand what has changed, what is new, and how to keep your fleet compliant.
The keyword “upd” indicates a revised version of the reference manual. NDC is not static—IATA releases new versions (e.g., 17.2, 18.1, 21.3), and airlines adopt them at different paces. Each typically includes: NCR APTRA Advance NDC (Network Delivery Control) reference
Defines localized hardware parameters and initial startup states.
Message Authentication Code (MAC) Failure; data integrity compromised. EMV ICC Integration and Security Compliance The is the bible for technicians and implementers
Enhanced EJ (Electronic Journal) features and support for dual cash handlers were added in updated versions.
This is usually the densest chapter. Look for updates regarding specifications. As contactless limits rise globally, the NDC protocol must send more data to the host during a "tap."
Standardized state tables specifically designed to handle quick tap-and-go transactions without requiring full card retention. Security and Encryption Hardening
