I'm sure most everybody knows ways to trick or fool a fingerprint scanner, but how many people know an exact proven procedure that works most of the time. The procedure here is based on a study by Dr. Matsumoto on 'gummy' fingers.

  • Materials Needed:
  • Graphite Powder or Superglue
  • Digital Camera or Scanner
  • Transparency Film (acetate)
  • Ferric Chloride
  • Gelatin
  • Silly Putty
  • Photosensitive Coated Copper Clad Board

[list=1]Procedure:[*]Use the graphite powder to make the print become visible OR use fumes from the superglue to get the same effect.[*]Scan the fingerprint image into your computer OR take a good quality digital picture of the print.[*]Use Photoshop or other graphics editor to inverse colors and increase contrast so fingerprint is clear and bold.[*]Print inverted fingerprint image onto the acetate (transparency). We need light to shine through it where the fingerprint should be.[*]Enter a dark area, place the transparency over the copper clad board, and expose to UV light for brief amount of time. This will eat away at the thin top layer where the fingerprint mold should be.[*]Soak the board in the ferric chloride. The solution eats away where the photosensitive layer is missing.[*]The fingerprint mold will emerge in the board, proceed to pour gelatin over the board.[*]Voila! Fake fingerprint [/list=1]

The created print can be used to fool most fingerprint scanners, and if sprayed with a little bit of WD-40, it will leave behind a fingerprint as your real finger would on surfaces. Don't do anything illegal now! This is merely a BRIEF procedure of how this method can be achieved, if you are considering doing this and need help, or are stuck... I'm happy to answer any questions. Also, if you're looking for ways around other biometric systems, ask away.
