False Security

  			Abstract

�Why 130 million Wiegand cards are in use throughout the world .

The most secure of all access card technologies.

HID Wiegand cards are virtually impossible to counterfeit... any attempt
to 
alter them destroys them! ...

Since no direct contact with the card is required, they are totally
enclosed,
making them absolutely immune to the elements and a frustration of
vandals. ... 

     	The secrets to the security of an
  	HID Wiegand card are those little
      	enclosed wire strips. Once corrupted,
  	they won't work.�

Would this be worth some bucks?

I would need a BRILLIANT EDITOR to help polish
the ms.  http://www.aci.net/kalliste/

On the other hand, we POSSSIBLY could get this UNFORTUNATE MATTER
SETTLED before it gets WORSE.

Counterfeiting Wiegand Wire Access Credentials

                  Wiegand wire access credentials are easy and
                  inexpensive to counterfeit.
     
        Access Control & Security Systems Integration magazine, October
        1996 [http://www/securitysolutions.com] published the article,
     
             Wiegand technology stands the test of time
     
             by PAUL J. BODELL, page 12
     
             Many card and reader manufacturers offer Wiegand (pronounced
             wee-gand) output.  However, only three companies in the
             world make Wiegand readers.  Sensor Engineering of Hamden
             Conn., holds the patent for Wiegand, and Sensor has licensed
             Cardkey of Simi Valley, Calif., and Doduco of Pforzheim,
             Germany, to manufacture Wiegand cards and readers. ...  A
             Wiegand output reader is not the same thing as a Wiegand
             reader,  and it is important to understand the differences.
     
                In brief, Wiegand reader use the Wiegand effect to
             translate card information around the patented Wiegand
             effect in which a segment of a specially treated wire
             generates an electronic pulse when subjected to a specific
             magnetic field.  If the pulse is generated when the wire is
             near a pick-up coil, the pulse can be detected by a circuit.
             Lining up several rows of wires and passing them by a cold
             would generate a series of pulses.  Lining up two rows of
             wires - calling on row "zero bits" and the other "one bits"
             - and passing them by two different coils would generate two
             series of pulses, or data bits.  These data bits can then be
             interpreted as binary data and used to control other
             devices.  If you seal the coils in a rugged housing with
             properly placed magnets, and LED and some simple circuitry,
             you have a Wiegand reader.  Carefully laminate the special
             wires in vinyl, and artwork, and hot-stamp a number on the
             vinyl, and you have a Wiegand card.
     
             IN THE BEGINNING
     
               Wiegand was first to introduce to the access control
             market in the late 1970s.  It was immediately successful
             because it filled the need for durable, secure card and
             reader technology.
               Embedded in the cards, Wiegand wires cannot be altered or
             duplicated. ...
     
        Bodell's Last statement is incorrect.
     
        Tasks for EASILY counterfeiting Wiegand wire cards are
     
        1    Locate the wires inside the card to read the 0s and 1s.
     
        2    Build an ACCEPTABLE copy of the card.
     
        Bodell's clear explanation of the working of a Wiegand card can
        be visualized
     
             zero row    |     |   |
     
             one row        |          |
     
             binary      0  1  0   0   1
             representation
     
        Solutions to Task 1
     
             A    X-ray the card
     
             B    MAGNI VIEW FILM,  Mylar film reads magnetic fields ...
                  Edmunds Scientific Company, catalog 16N1, page
                  205, C33,447  $11.75
     
        is placed over the top of the Wiegand card.
     
        COW MAGNET,  Cow magnetics allow farmers to trap metal in the
        stomachs of their cows.  Edmunds, page 204, C31,101 $10.75
        is placed under the card.
     
        Location of the wires is easily seen on the green film.
     
        Mark the position of the wires with a pen.
     
        Next chop the card vertically using a shear into about 80/1000s
        paper-match-sized strips.
     
        Don't worry about cutting a wire or two.
     
        Note that a 0 has the pen mark to the top.  A 1 has the pen mark
        at the bottom.
     
        Take a business card and layout the "paper match"-like strips to
        counterfeit the card number desired.
     
        Don't worry about spacing.  Wiegand output is self-clocking!
     
        Tape the "paper-match - like" strips to the business card.
     
        Only the FUNCTION of the card needs to be reproduced!

        National Laboratories beginning in 1992 funded by the Federal
        Bureau of Investigation/Engineering Research Facility, Quantico,
        VA.
     
        The FBI opined that this work was SECRET/NATIONAL SECURITY
