Paypal & asp.net

[Blasting Cap]

I have an application that needs to use Paypal to verify the legitimacy
of a credit card, not the actual charge.

The only thing I can find thru Paypal's SDK is stuff that's a COM add-in.

Is there a web service that anyone knows of that'll do this process?
One that would be free or a single-time fee would be preferable.

Any help appreciated.

When you say 'legitimacy', do you simply mean checking that the card number
is a valid credit card number...?

More or less - what we would be doing is authenticating the card, and
making sure that the expiration date on it is valid, and then passing
that info on to another application that would actually do the billing
of the credit card when the item ships.

Hi,

Why don't you consider wrapping the com component? A few second works and
free (although, of course, you would be stuck with some unmanaged code).
Hope this helps.
Regards.

Well, if all you need to do is check that it's a valid card number and that
it hasn't expired, you can do that with just a few lines of code...

There is a validate card method that you may be able to integrate in
your project.

You can Mod10 check the card and make sure date is in the future. Beyond
that, you have to run an authorization. PayPal pro can do this, but it is a
pay service. I know of no "check for valid card" free or one-time fee
services.
