** .NET Framework 3.5 (includes versions 2.0 and 3.0) must be enabled from the Control Panel > Programs & Features > Windows Features screen prior to installation of Keyscan software.

*** Supports virtual machine server topology providing that all licensed and required Keyscan software applications are allocated sufficient server resources for proper system performance and that the VM software/server is supported by qualified IT personnel.

Keyscan has tested OS compatibility with System VII but makes no guarantee for OS compatibility with third party software applications or third party drivers.

For sites with large cardholder populations and high volumes of transactions, we strongly recommend that you install the Database Module (SQL Server 2005 Express) on a dedicated PC. Faster processors and higher RAM provide better system performance. To confirm that your PC meets the recommended requirements, you can view the PC's system information by selecting Start > (All) Programs > Accessories > System Tools > System Information. System VII does not support touch screen panels.

For systems that exceed 12 access control units and/or 100 readers, you may request Keyscan’s System Architecture White Paper for additional specifications and recommended communication configurations to derive optimum system performance.
