Rick,

These IP gateway providers like Authorize.NET or PayFlow Pro impose additional per transaction charges on the top of the charges of the credit processors. Today many processors establish their own IP gateways so users can avoid intemediate "gateways". We provide products that can interface directly to Paymentech, Vital, Lynk Systems, and others. We have seen transaction speeds under one seconds with the broad band connection.
