Before I start, I know Delphi very well but I've never done any internet processing in any shape or form.
What I want is to construct a simple page that will allow users to license my software.
The logic is:
1. user connects to the license page on the web
2. enters licensee name
3. enters card details
4. some payment portal processes card payment
5. on successful payment transaction key is generated and displayed
6. confirmation email with the key is sent to client and to me.
I would need some guidance on steps and tools to use and it would help to get advice on which portals to use. I've searched the net on different portals, some require just to include script in HTML others require some other forms of registering. Some charge setup and monthly fees others per transaction, and other seem not to charge anything. I'm not sure if any of them could be fraud so I'm relying on your advice.
