More specifics

software must be written in .net and should be like this

TCP server that will listen for incoming connections ( listening ip and port must be configurable)

Incoming XML will be verified with a hash to verify the integrity of the xml

XML will be then converted to ZVT, send to Payment Terminal and reply back to client with the relevant xml.

ZVT Communication with the payment terminal should be also exportable and usable as dll.

So Idealy the main software will be the TCP server, XML convertor and dll adon the ZVT Library

Currently we have a version that is only usable in windows 10.

we would like to have our software compatible with windows xp and above

We can provide the code we currently use which is .net 4.5.2

we need someone to rewrite the code to be compatible with windows xp and above.

and also to have a good knowledge of the zvt protocol.

We will help in the QA of the code

Please only experience people with ZVT protocol and .NEt to apply

i will provide further details in email

People that will apply for this project must definitely know ZVT protocol since it's difficult to do it without working experience with it.
