ASP.NET application with credit card payments

Question

I might go into a web project that involves credit card transactions, which I have not done previously. The transaction will go through Authorize.NET or may be PayPal.

During user log-in will Forms Authentication be sufficient?

What are other considerations/.NET technologies, particularly with security that I need to research?

Answer 1

Authentication is unnecessary unless you need to keep track of orders per specific user. Some eCommerce systems like nopCommerce allow guest transactions, for example. What you do need is a SSL certificate from a reputable certificate authority. The rest can be gathered by looking at some code samples like Authorize.Net has.
