Re: standalone 125KHz RFID card cloner

125 kHz RFID cards, also referred to as LF cards, are still very 
common.  Although I have no hard numbers to back this up I'd venture to 
guess that HID Prox cards are still the most widely deployed access 
control card in the US and these cards are 125 kHz cards.  The only 
thing that might throw this off is all US government organizations have 
migrated to 13.56 MHz cards.

In the 125 kHz range there are three types of RFID you'll commonly find 
used by access control systems.  They are HID Prox, Indala and EM4100 
(EM).  From what I've been able to research the device listed can only 
clone cards that use the EM4100 chip.  EM cards tend to be used in 
small/off label access control systems.  I've mainly seen EM cards used 
at gyms and parking garages.  I've seen them vary rarely used for access 
control in an office environment.  So depending on what you want to do 
with it it might have limited usefulness.

As part of an ongoing research project I'll probably be order the device 
listed below as well as the reader, cards, panel, etc to build an access 
control system.  Once all that stuff arrives I can confirm the devices 
capabilities.

In October I'm doing a presentation called Access Control Cards: The 
Good, The Bad and The Clonable at the Cleveland Information Security 
Summit.  After this talk I'll be doing some more blog posts and white 
papers on what I discovered and will be getting into more depth on both 
125 kHz and 13.56 MHz cards.

Cheers,
Matt

I was under he impression from a freind of mine that 125KHz  was 
mostly for hobbiest stuff. Anyone know? One of the reviewers said his 
parking pass was a 125KHz.

Thanks,

    Just found this standalone 125KHz RFID card cloner, I wondered if
    anyone had seen one of these or if they thought it was worth the $66.
