NDC Host Emulator 2.0

NDC Host Emulator by NCR is a software tool that simulates an NDC-acquiring host, enabling ATM teams to test and validate NCR NDC/NDC+ device behavior and transaction flows in a controlled lab environment—without connecting to a live switch. It streamlines development, certification, and regression testing by providing realistic host responses, scenario scripting, and detailed diagnostics.

Key capabilities:

• NDC protocol emulation with configurable responses for common ATM transactions, including cash withdrawal, balance inquiry, funds transfer, deposits, PIN change, mini-statements, and administrative functions (as supported by your ATM software).
• Negative testing and fault injection, such as timeouts, denials, partial approvals, host-down simulations, reversals, and network delays.
• Cryptography simulation for key exchange workflows and MAC generation/verification aligned with NDC configurations, using test keys and personalization data.
• High-fidelity tracing and reporting with message-level logs, timing metrics, and exportable test results.
• Automation support for scripted test cases, batch execution, and integration with CI/CD or lab orchestration tools.
• Flexible deployment in standard Windows lab environments with support for multiple concurrent ATMs and sessions.

Common use cases:

• Accelerating ATM application development, configuration changes, and OS or platform migrations.
• Preparing for network certifications and software releases.
• Training operations and support teams in a safe, repeatable setting.

Benefits:

• Reduced testing time and cost
• Improved coverage and repeatability
• Lower risk before production rollout

Note: Actual features, supported NDC variants, and system requirements may vary by version and license. For precise specifications, contact NCR.
