It resembles a standard connector but inside the KEYKatcher is a microcontroller and a non-volatile memory chip.  The microcontroller interprets data (keystrokes) as they are typed and the non-volatile memory stores all of the keystrokes.

Installation

To install the KEYKatcher, all you need to do is plug it in between your keyboard cable and your computer.  The KEYKatcher is ready to record the instant you plug it in.  Heat-shrink tubing is provided with each KEYKatcher so that you may attach the unit to the keyboard cable.   This creates a tamper-evident seal which cannot be removed without your knowledge.

Retrieving data

When you want to see what's been recorded, simply open any word processing program (Microsoft WordPad is recommended) and type in your password.  As soon as your password has been correctly entered a menu will be displayed on your screen.  The menu gives you several options, including; View Memory, NETPatrol Search, Erase Memory, Disable recording, and so on.  As soon as the 'View Memory' option has been selected, every word that has been typed on your computer will be displayed for you to see!
