Dear friends

I am developing a project based on credit card processing for my last semester examinations ..

I want to develop a web based application which will enable users to buy goods and materials of their choice and then add to the respective cart.

At the end, they have to provide their credit/debit card numbers and secret code for payment section.

But the question is that, I am not able to know how to validate those credit card numbers and where to validate and related issues.

Kindly if it is possible, let me know these things or else please send me a link from where i can get those information.

It would be appreciable.

Thanks.

Regards,
Nayan Ambaliya.
