A functional minimalist credit card randomizer to test application.

Keep in mind that all credit card numbers generated with Cardizer are completely random and do not hold any real life value.

• Easy to use
• Easy to extend
• Thread safe
• Check with the Luhn's algorithm
• Support for Visa credit card
• Support for Jcb credit card
• Support for Amex credit card
• Support for Discover credit card
• Support for MasterCard credit card

Install the Dedge.Cardizer NuGet package:

PM> Install-Package Dedge.Cardizer

Alternatively you can also use the .NET CLI to add the packages:

dotnet add package Dedge.Cardizer

Next create a .net application and use Dedge.Cardizer:

open System

[<EntryPoint>]
let main _ =
    Dedge.Cardizer.NextVisa () |> printfn "Visa: %s"
    0

or in C#:

static void Main(string[] args)
{
    var card = Dedge.Cardizer.NextVisa();
    Console.WriteLine(card);
}

output:

Visa: 4127540509730813

Of course the credit card value is going to be randomized.

There is a F# sample application which can be found in the App folder and a C# sample application which can be found in the AppCs folder.
