Live Transaction Dashboard

Watch transactions stream in over WebSocket as your terminal processes them. Filter by terminal ID, view response codes, timing and raw protocol data.

Reports & Analytics

Build custom dashboards with KPI cards, charts, gauges and tables. Group data by time or terminal, create templates and track trends over time.

Test Scenarios

Define scripted approval rules — approve, decline, partial, timeout or system error — and share them with your team via public links.

Android Demo App

A ready-made Android payment app with NFC contactless support. Connects via APACS or ISO 8583, sends logs and reports automatically.

Remote Logging

Drop-in Android log replacement. Captures log messages, screenshots and images from the device and streams them to the web dashboard in real time.

Share & Compare

Generate public share links for transactions, log sessions and images. Compare results side-by-side with the built-in comparison tool.

TLS & MAC Security

Full TLS encryption on all connections. ANSI X9.19 MAC authentication for APACS transactions with automatic key derivation per session.

Rules Engine

Deterministic responses based on amount last-digit. Approve, decline, pick up, fraud, partial, timeout and more — all configurable per scenario.

Multi-Tenant

Each user manages their own terminal IDs, reports and scenarios. Admin portal with user management, platform stats and email integration.
