Android All in One SmartPOS: Ingenico Axium

Why Axium?

The Ingenico Axium is NMI's Android-based SmartPOS platform — built for developers who want to build powerful, reliable payment experiences on modern hardware.

If you're already using NMI's Payment Device SDK for Android, Axium is designed to feel immediately familiar. The integration experience mirrors existing supported devices, meaning your current Android application can work on Axium with minimal rework. And if you want to go further, Axium's open Android environment lets you build and ship a fully custom application directly on the device.

Here's what that means in practice:

• Familiar SDK, new hardware. The Payment Device SDK for Android works with Axium just as it does with existing devices — no significant rework required for current SDK users.
• Offline-first reliability. Transaction logic lives on the device, not in the cloud. Your integration keeps working even when connectivity drops, with deferred authorisations handled automatically.
• Flexible connectivity. Connect over WiFi, Bluetooth, or USB — choose what fits your integration architecture and your merchants' environment.
• Build your own app. Axium runs Android, and NMI provides the tooling to securely sign and distribute your own applications across your entire device estate.
• Modern hardware, familiar gateway. All the processing power and UX flexibility of a current-generation Android device, backed by the NMI gateway you already know.

Ready to Integrate?

The SmartPOS: Ingenico Axium section walks you through the full integration: unboxing, device setup (Wi-Fi, Bluetooth, app inventory), platform-specific requirements (Lite vs Full SDK flavours), and the SmartPOS API deltas — required and disallowed transaction parameters, new parameters for offline / partial-approval / external signature verification, event and error-code differences, the offline transaction queue, disconnection handling, OTA updates, log retrieval, and supported-methods / supported-features reference tables.
