Photo Gallery

The photo below shows the KeyCarbon USB series with the default black "skin".

Figure 1 - Unit with a BLACK "skin" fitted (these "skins" can easily be swapped by the user)

The photo below shows the KeyCarbon USB series after the supplied white "skin" has been fitted to the unit. Most Macintosh users prefer a white unit. The spare shells can easily be swapped in about 30 seconds, by levering the black shells off with finger pressure, and fitting the supplied white shells.

Figure 2 - Same unit with a WHITE "skin" fitted (a spare white "skin" is supplied with each unit).

The photo below shows the electronics inside the KeyCarbon USB series. You can see in the image below that the "skins" pull apart with finger pressure, and can easily be swapped by the user to change the units colour.

USB Keylogger Comparison

KeyCarbon products work on every keyboard, as they use an expensive FPGA (Field Programmable Gate Array). Currently, all other other brands of USB keyloggers use cheaper hardware, and thus do not work on some keyboards.

USB Keylogger Comparison
Brand Problem? Reason? Rating?

Brand "KeyCarbon" is compatible with all known USB keyboards (a tiny proportion of future keyboards may require a firmware upgrade which can be downloaded from the internet).

KeyCarbon uses an expensive FPGA (Field Programmable Gate Array) chip to interpret USB traffic. This solution works well on all known keyboards. KeyCarbon is firmware upgradable so your unit can be upgraded by downloading an upgrade from the internet. Comes supplied with both black and white skins (for PC and Macintosh users). 100%
Brand A. Brand "A" does not work if a USB flash drive or any other non-keyboard peripheral is plugged into the USB keyboard. Does not work with certain Logitech wireless keyboards. Does not work on high end Macintosh keyboards. Units are not made in the USA, and are shipped from a warehouse in the country of New Zealand. Brand A uses a USB host/slave chip. This method does not work if any additional devices are plugged into the keyboard. If non-keyboard traffic is detected, it will overload the chip making the keyboard cease to work or behave erratically. Comes in black only, no option for white (ie: not suitable for Macintosh users). 90%
Brand B.

Brand "B" does not work on some USB keyboards (it is difficult to tell in advance with whether it will work or not).

Brand B uses a barrel shift chip (1/100th of the cost of a FPGA chip and 5% of the processing power). This method does not work on some keyboards. Has no USB hub chip. 80%
Brand C Currently there are no other known brands on the market - email support if this changes and we will update this comparison. - -

Start of review: "The packaging consists of a plastic jacket, similar to DVD-packaging, which is sealed. Included is not only the hardware keylogger but also a short reference for quickstart and a white case, which can be exchanged with the black one". Read more.

Product Review: Whats My Pass?

"I had a chance to review the Keycarbon USB Home Mini this week. I’ve been wanting to try one of these to see how they would compare to a PS/2 keyboard logger, PS/2 is still pretty popular as far as cheaper keyboards but the shift in is going more towards USB keyboards. I was pretty impressed by the quality of the keylogger and its installation ...". Read more.
