After years of development and testing on many platforms, Hansa.net has created two products for the Payments System Integrator and processors.
We offer two .NET packages for credit card transactions:
1) VISA2 format transactions
2) ISO8583 format transactions
Both collections include modules for backend databases, management, high speed, reliable, and scalable transaction processing.
