Secure Electronic Transaction?  Look around the internet using a search engine.  Cybercash is one example.  IBM's SET is another.  There may be free implementations too.  If not, then the whitepapers may help you in SETs.

But then, maybe I didn't understand your question in the first place.

You can use any language to create a cgi that:
- ask 'login' and 'passwd'
- do some confirmation on DataBase included on the server
- if there are correct ask for the rest of data fields

You should use a language that work easely with DB. This facilite you the work.

Viro, what you're proposing isn't set for secure transactions.
It just authenticates through the web and THOSE information can be captured and read(especially cleartext).  Thus it is not safe. If I were you lihua, I'd look into papers on Secure Transactions on how to go about this.
