I cannot use AIM,
Here are the differences
SIM doesn't collect credit cards on your own site. It sends the customer to authorize.net's website to checkout on their secure page.
AIM collects credit card info on your own site and processes the cards in real time while the customer waits and never leaves your payment process. A ssl certificate is required and Curl+SSL is required to be compiled into php for AIM to work.

I have an SSL certificate but I process from authorize.net because I do not want to be liable for anything.
So that is not an option for me.
ANyone know coding can fix the SIM>>>???
