Does anyone know if authorize.net's SIM rids you of having to be PCI compliant? The payment form is hosted on authorize.net's site and they're processing the payment.
I know you can do a relay response which basically puts some of the transaction details in a url that goes back to your website(to display a receipt). I'm not sure what all information gets put into the url though. I'm wondering if that makes you have to become PCI compliant?
