Develop an App for myPOS Smart Devices

This guide walks you through creating, integrating, and publishing an Android business app for myPOS Smart terminals using the myPOS Smart SDK.

1. Create a New Project

Developing apps for myPOS Smart devices is similar to building standard Android applications. You’ll use Android Studio and the myPOS Smart SDK alongside standard Android APIs.

• Recommended IDE: Android Studio
• Programming Language: Java (C/C++ possible via Android NDK)

2. Choose Your App Type

You can develop apps for a wide range of industries and use cases:

• Taxi and Transportation
• Restaurants and F&B
• Retail
• Hotels and Booking
• Leisure
• Professional Services
• ...and more!

Compliance Limitations

• The Android Settings menu is locked on myPOS Smart devices.
• All production apps must be signed with the manufacturer’s PCI Certification Key to be installed on non-test devices.

3. Integrate the myPOS Smart SDK

The myPOS Smart SDK enables direct communication with the terminal's hardware and services to process card payments and interact with secure components.

Key Features:

• Process payments with support for Visa, Mastercard, UnionPay, JCB, Bancontact, and others
• Initiate refunds, voids, and pre-authorizations
• Handle Payment Requests
• Access POS info and terminal components
• Operate SAM Modules
• Print last transaction receipts and custom receipts with images (e.g., QR codes)

Built-in SDK Functionalities

With the SDK integrated, your app can:

• Receive POS info
• Process checkout payments
• Issue refunds
• Send payment requests
• Void transactions
• Control SAM modules
• Print receipts (last transaction & custom)

4. Finish Your Project – Build the APK

Use Gradle in Android Studio to build and package your app. Android Studio automates builds and allows for advanced configuration via build.gradle.

📘 Official Build Guide

Manifest File Example

Set your SDK levels and versioning:

<manifest
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:versionCode="1"
  android:versionName="1.0.1"
  package="name.of.your.app">

  <uses-sdk
    android:minSdkVersion="19"
    android:targetSdkVersion="27" />

  <!-- Your application declaration and activities go here -->

</manifest>

Versioning

Each new version must increment:

android:versionCode="2"
android:versionName="1.0.2"

SDK Compatibility

App Label

The name shown on the terminal comes from the android:label property in your manifest—not the AppMarket listing.

Launcher Type Apps Not Allowed Do not include this in your activity:

<category android:name="android.intent.category.HOME" />
