HID Global of Irvine, California, has developed several solutions that now support logical access control as well as physical access control. Now, iCLASS contactless smart- cards can be read by the embedded contactless smart-card reader in select models of the Dell Latitude E-Family laptops so users can use the same card for building access and secure authentication for the computer. Crescendo smart-cards offer high security through multiple technologies and provide standards-compliant support for existing physical and logical access applications. The naviGO software package enables an organization to use its existing physical access control cards for two-factor authentication at the desktop. The OMNIKEY 6321 is a USB-connected dongle reader that supports the use of contactless smart-cards for secure two-factor authentication in a mobile computing environment.
