credit card validator

Hi,

I’m looking for a credit card validator. Now if you google for that there are enough options does someone have good or bad experiences with some?
And if I’m correct it doesn’t connect with any database, so it doesn’t check for stolen cards ect..right?

Thanks in advance

 

I do not think that you will find any "google found" credit card validator that is connected to the bank network.

 

The only thing you will find without signing up with a payment processor or a merchant account provider, is something that will check the number to be valid using the Luhn algorithm.

If you wanted to actually check if the card was valid, you would have to run an auth transaction on the card.

There is no publicly available database or service that will validate a card number / expiration date. This would be a dream come true for someone stealing or generating credit card numbers.

 

Thanks for the reply’s

Ok I understand the luhn method, and otherwise you have to use a paymentservice provider to authorize the credit card.
Has anybody a good recommendation about luhn software which easily can be integrated in your own software?

 

There are some PHP ones here:
