Moneris Payment Integration for C#.NET POS

Job ID: 39362206

Budget: $150 – $250 USD

I need to integrate a Moneris AXIUM DX8000 payment terminal with my existing C#.NET POS software on Windows. The POS is written in Visual Studio 2022. .NET Framework 4.8 will be a preferred framework for this project.

The integration should use Moneris SDK and support the following transactions:
- Purchase
- Void Last Purchase
- Refund

All these transaction requests should have a corresponding transaction response to allow the POS to save some of the transaction data into a SQL Server database or a text file. The data to be saved includes:
- Transaction ID and amount
- Cardholder details

An Object Oriented Programming approach will be preferred. No POS user interface changes are required. A simple Winform UI project should be added to the solution to test the functionalities specified above. Technical documentation is also required.

Ideal candidates should have:
- Experience with C#.NET
- Familiarity with Moneris SDK
- Strong background in payment processing integration
