Introduction

Welcome to /n software 3-D Secure, an extensive development toolkit for implementing any EMV® 3-D Secure program into online shopping carts, websites, or merchant systems. The included Server component allows for easy integration with Visa EMV 3DS, MasterCard Identity Check, American Express Safekey, Discover ProtectBuy, J/Secure, and more.

Included Libraries

The .NET Edition includes libraries (.dll files) which are supported in different environments. The following libraries are present in the lib directory after installation:

  • lib\net40\nsoftware.IPWorks3DS.dll is designed for use in .NET Framework 4.0 and up. This library maintains a familiar API in line with previous versions of the product.

  • lib\net6.0\nsoftware.IPWorks3DS.dll is designed for use in .NET 6 and up. The .NET 6 library provides cross-platform support while maintaining the same API as the .NET Framework version of the library.

    Support for asynchronous programming patterns (async/await) is exposed in a separate nsoftware.async.IPWorks3DS namespace. See the Async Functionality page for details.

  • lib\netstandard2.0\nsoftware.IPWorks3DS.dll is designed for use in .NET Standard 2.0 and up. The .NET Standard library provides cross-platform support for legacy projects.

Included Components

CardValidator The CardValidator component is used to verify that a given credit card number is formatted properly, and could be a valid card number. Validating a card before actually submitting a transaction for authorization can reduce the fees that may be associated with invalid or declined transactions.
CertMgr The CertMgr component is used to create, read, and manage certificates.
Client The Client component is designed for use on mobile devices and facilitates EMV® 3-D Secure authentication.
Server The Server component provides support for the 3DS Server role as defined in the EMV® 3-D Secure (EMV 3DS) specification.
