asp.net : Credit card validation

I need a credit card validator. Is there reliable code already written that
anyone knows of? I have come across a few things; i.e. the Luhn-10
algorithm, but don't know if that still applies or is obsolete and
additionally, how would I incorporate it into a vb.Net app?

Does anyone have helpful links?

Luhn formula still works. Here's a javascript implementation of Luhn:

You can somehow incorporate it into an ASP.NET page yourself, or you could
use a 3rd party validator that does credit card validation like this one:

Sandy,

Have a look at this article. It contains a demo code and an asp.net control
which does basic validation

A CreditCardNumberValidator is one of the 25 validators in my Professional
Validation And More (http://www.peterblum.com/vam/home.aspx). Its fully
tested, supports client-side validation (on many more browsers than the
ordinary Microsoft validators), and allows customizing the list of credit
card brands.
