Why n2Tap

Everything you need to ship SoftPOS

Built for mobile app teams, ISVs, and POS integrators who need a secure, customizable integration with fast time-to-market.

Secure by default

Sensitive operations — PIN entry and card read — are isolated inside certified SDK modules. PCI CPoC / MPoC compliant out of the box.

Fast integration

Send Android intents or use n2app-lib to construct and receive structured payment responses in minutes, not sprints.

Headless & composable UI

Build your exact payment UX using Jetpack Compose, XML layouts, React Native, or Flutter. No forced UI — pure control.

Production-ready docs

Well-documented APIs, structured response codes, release notes, and runnable examples for every supported platform.

Quickstart

Ship in 3 steps

From zero to a live card-present transaction — with full UI customization and structured responses.

Install the SDK or plugin

Add the Headless SDK or the platform plugin (React Native / Flutter) to your project via your package manager.

Initialize with your credentials

Configure the SDK with your enabler credentials and attach lifecycle hooks to your Activity or AppDelegate.

Start a transaction

Fire an Intent or call the SDK API — get a structured JSON response with status, transaction ID, and masked card data.
