Is there anyone out in ZenCart land using the uSight gateway? We're using a payment module originally developed by Merlinpa1969 long, long ago (and fiddled with by me -- mostly adding the uSight API documentation). But I'm getting a bit nervous about PCI-DSS (in particular PA-DSS) compliance at both our end and at the uSight end. Should we consider switching to another service like PayPal or authorize.net, or, or, or ...?
