The Dell Latitude D420 is a business notebook computer with an Intel Core processor. A fingerprint reader is one of the optional components available for the Latitude D420, and if you have one installed, you will notice the scanning pad between the left and right mouse buttons. The software needed to use the fingerprint reader is coded into the hardware of the Latitude D420. To use the fingerprint reader, you must install the software from within the Latitude D420 motherboard set-up, before Windows loads.

Tips and warnings
