Sttl_Authorize

The extension does not store CVV information and is thus PCI Compliant.
All credit card related sensitive information will be saved on the Authorize.net secure servers. This makes your website completely SAFE and PCI compliant.
A unique transaction ID will be created with each order. Using this transaction ID, we can capture payment, make refund and partial refund.
Place orders through the Magento back end using the module and get payments in realtime.
Enable/Disable the saved credit card details feature. If it is enabled, customer entered CC details will be automatically stored once the transaction is complete.
The stored Credit Card details are displayed to customers in DROP DOWN to select any one at time of second payment.
Split invoices or Multiple Invoices can also be generated for a single order.
