Hello,
I have put up a new plugin for integration with Authorize.Net using 'Server Integration Method' (SIM)
This is the hosted payment solution which does not require collection of credit card data on your site. Therefore it provides secure way for processing credit card transactions.
You can get it from http://mayotitech.com/products.php Its name is 'VANPP SIM' You can use coupon code c98uio to get discount.
Regards
