What exactly is involved with using Authorize.net?

Is this what you want?

So, it's secure, but the form page isn't SSL, and this might scare the buyer.

 

If you loop closely at the picture, they are telling you that your form must be HTTPS.

The client is teeter-tottering on the credit card transaction fee percentage.  Paypal and Google Checkout have a 2.9% + $0.30 fee, while their Merchant is (somehow?) hooking them up with a 1.58% fee.  I went ahead and set up a sandbox account and used the SIM integration method just to check it out.  There are still a few variables I need to figure out, but it seems I may be able to get away with no getting an SSL.  The form action posts to a https address hosted on Authorize.net, which is exactly what I need.

 

Now I just need to make sure I meet the requirements.

Watch out, having the form on a non-secure page opens yourself up to MitM.

 

If an attacker were to manage to compromise the stream between your webpage and the server's, it's possible to modify the HTML before passing it through, changing your form's action.

 

Though, this form of attack isn't exactly easy unless your client's on weak WiFi when he/she does it.
