Download

Donwloading the package from NuGet

You can download the IngenicoPOS Package form NuGet, which will automatically download all of the necessary dependencies, or you can install it with:

• Package Manager

Install-Package IngenicoPOS -Version 1.0.1

• .NET CLI

dotnet add package IngenicoPOS --version 1.0.1

• Paket CLI

paket add IngenicoPOS --version 1.0.1

or by adding PackageReference:

<PackageReference Include="IngenicoPOS" Version="1.0.1" />

Manually downloading the assembly

1. Download the latest release IngenicoPOS.dll from IngenicoPOS Releases
2. Put the IngenicoPOS.dll to your project dependencies
3. Add the IngenicoPOS.dll as a project dependency

NOTE: Make sure the project also depends on System.IO.Ports

Usage

Import

To use the available classes, you will need to import them into the project (unless you really want to type IngenicoPOS. every single time):

using IngenicoPOS;

Connection

To Connect with the POS device, we will initialize POS class and connect to it

const string PORT = "COM9";  // Port of the POS Device (COM0 is just an example)

POS posDevice = new POS(PORT);
posDevice.Connect();  // Will return true if connection is made, otherwise will return false

// To check whether the posDevice is connected, we can do it with
if ( posDevice.IsConnected ) {
    // The device is connected
} else {
    // Nope :/
}

Sale

To charge a card, we can use the POS.Sale( Amount ):

const string PORT = "COM9";  // Port of the POS Device (COM0 is just an example)

POS posDevice = new POS(PORT);

if ( posDevice.Connect() ) {
    // We will charge the card for 100,00
    SaleResponse res = posDevice.Sale(10000);

    if ( res.Success ) {
        // Sale was successful :D
    } else{
        // Sale wasn't successful :(
    }
} else {
    // Device not connected :/
}

Development

1. Clone the repository with

git clone https://github.com/F4pl0/ingenico-pos-dotnet-lib.git

2. Open in Visual Studio 2019 (To eliminate compatibility issues)
3. Get Dependent NuGet Packages (If they aren't already in the project)

Happy Development

Dependencies

• NuGet MSTest.TestAdapter Tests only
• NuGet MSTest.TestFramework Tests only
• NuGet System.IO.Ports Required for library

Tests

1. Test01Connection
   Tests the connectivity with the device on the PORT port.
2. Test02Sale
   Upon connecting, tests the POS.Sale( Int64 Amount ) Which returns SaleResponse.
   The main test is to check whether the SaleResponse.Success is true
