NDC Host Simulator

NDC Host Simulator is a purpose-built testing and validation tool that emulates an NCR Direct Connect (NDC) host, allowing teams to develop, test, and certify ATM and self-service terminal software without relying on a live switch. It reproduces typical host behaviors and message exchanges so you can verify transaction flows, state transitions, and field formatting in a safe, controlled environment.

Key capabilities:

• Host-side emulation of NDC request/response cycles, including sign-on, state tables, and transaction authorization outcomes
• Configurable scenarios for approvals, declines, timeouts, reversals, and fault conditions
• Real-time message tracing and logging with field-level inspection for quicker troubleshooting
• Customizable field mappings and validation rules to accommodate institution-specific variants
• Multi-session support to test multiple terminals concurrently and simulate load
• Automation hooks for regression testing and continuous integration workflows
• Detailed reporting and exportable logs to support QA and certification evidence

Typical use cases:

• Functional and integration testing of ATM applications and device handlers
• Regression and pre-deployment verification in lab environments
• Operator training and demo scenarios without production risk

Benefits:

• Shortens test cycles by removing dependency on external hosts
• Improves quality through repeatable, automated tests and precise diagnostics
• Reduces risk by validating edge cases and failure modes before rollout

Note: Feature support and connectivity options can vary by deployment; verify compatibility with your target ATM software and network setup.
