Cardizer is a credit card randomizer to test application. Maintained by folks at D-EDGE.

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

Features

  • 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

Getting Started

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.
