We need to make a simple test application for integration with a new type of payment terminal. We have all the needed documentation, and we will also provide a picture of a similar software that we are using on older payment terminals. The library is for .net (NuGet package with support for .NET Standard 1.5 & 2.0, .NET Framework 3.5, 4.0, 4.5 or later and .NET Compact Framework 3.5) The documentation is quite easy and straightforward. We would prefer to get builds and test them our self, but if needed access to a machine in the same network as the payment terminal can be given. It needs to be programmed in C#. We cannot give out to much information at this point, as an NDA will need to be signed. Previous work with Ingenico or Verifone Payment terminals is a pluss.
