Overview

What is n2Tap?

n2Tap is a SoftPOS solution that enables secure card-present payments directly on Android devices.

Instead of implementing complex payment logic yourself, your app integrates with n2Tap via App-to-App communication.

Your app triggers n2Tap to perform transactions, and n2Tap securely handles the rest.

How App-to-App Integration Works

n2Tap operates in App-to-App launch mode using Android Intents.

When integrated:

1. Your app sends a structured Intent request.
2. n2Tap launches and processes the requested action (e.g., start transaction).
3. n2Tap returns a structured response to your app.

This approach ensures:

• Secure isolation of sensitive payment logic
• Clean separation between your app and payment processing
• A consistent and certified payment experience

Using the n2app-lib Wrapper

To simplify integration, we provide n2app-lib, a dedicated wrapper library.

It helps you:

• Construct valid Intent requests
• Send transaction or configuration commands
• Receive structured responses
• Handle data parsing automatically

The wrapper abstracts the low-level communication details so you can focus on your application logic instead of Intent formatting.

Supported Platforms

n2Tap provides SDKs and plugins for multiple environments:

• React Native Plugin – For cross-platform mobile applications
• Flutter Plugin – For Flutter applications
• Kotlin SDK – For native Android applications

Choose the integration method that matches your tech stack.
