Getting Started

Our mPOS solution is aimed at people who may not have access to (or requirement for) traditional POS hardware. With support for Android and iOS it makes taking payments on the go simple and hassle free.!

mPOS Devices

The first step in getting started is to pick your mPOS device from the following list of manufacturers. If you haven’t already, follow the links below to see details about your device.

Before proceeding, please make sure your device is setup successfully. Check the Devices section to learn how to setup your device.

How to Integrate

<Code Samples>


1. Setup and Authenticate.

Setup the SDK using the initialize command. There are 2 ways to use this method.

  • Pass an object that implements the CoreAPIListener interface. (the this in the code sample)
  • Pass no argument and make subsequent calls to register*Listener to register callbacks in different locations depending on the structure of your application.
Only one of these implementations should be used. i.e. don't register multiple listeners if you are using the CoreAPIListener this will lead to duplicate callbacks firing.
The initWithConfiguration call will authenticate with the Worldnet gateway and retrieve settings required for operation. The onSettingsRetrieved callback will fire on success. At this point we know that we have successful credentials and the SDK is ready to connect a device.

  • Android
  • IOS

AndroidTerminal.getInstance().initWithConfiguration(MainActivity.this, TERMINAL_ID, SECRET);


[[WTPSTerminal singleton] init:self];
[[WTPSTerminal singleton] setMode:TEST];
[[WTPSTerminal singleton] initWithConfiguration:TERMINAL_ID withSecret:SECRET];


2. Initialize the device.

You can now initialize the device. Use this code and wait for the device to connect. Change the device name and connection method to match your needs. The onDeviceConnected callback will fire on success. Once this fires the SDK and device are ready to use!

  • Android
  • IOS

AndroidTerminal.getInstance().initDevice(DeviceEnum.IDTECH, DeviceConnectionType.USB, null);


[[WTPSTerminal singleton] initDevice:BBPOSDEVICE withConnectionType:BLUETOOTH withBluetoothAddress:nil];


3. Perform a transaction.

Once the device is connected send the amount required via a ProcessSale call and the device should prompt for a card. Presenting a valid card should result in an online authentication being sent to the bank and the SDK processes the response. The onSaleResponse callback will fire on success. Here is where you can display receipts or do any other post transaction processing.

  • Android
  • IOS

CoreSale sale = new CoreSale(BigDecimal.valueOf(Double.parseDouble(2.22)));


CoreSale *sale =[[CoreSale alloc] init];
sale.amount = [NSNumber numberWithDouble: 2.22];
[[WTPSTerminal singleton] processSale:sale];
