Any authentication method can be fooled however smell is going to be quite challenging.
I guess you could stalk your target and try to steal their sweaty clothes.

  Actually a combination of smell, voiceprint and passphrase would be good.
  Say your passphrase into the micro-smellophone (with voice recognition).
  Bonus points if 'twere muffled such as to stifle eavesdropping.

  Yeah, none of them seem 100% secure to me. I went with Retinal, because I tihnk for most smaller crimes at least criminals a re unlikely to go to the trouble of cutting out an eye.
  At least, I hope they would be.

  That might not help, if authentication is based on odor: http://idle.slashdot.org/article.pl?sid=08/11/11/2223205/ [slashdot.org]

    I forgot to add. A two factor authentication is always better than just one.

    Do sweaty clothes not contain a person's odour?

I remember seeing a tv program about the East German Secret Police and the kind of stuff they kept on file. They even developed a method for saving smells and and they had a massive catalog of smells from different crime scenes. The show went on to say that though the methods of gathering evidence worked, and they gathered a tremendous amount of it, they soon had so much data that they could not sort through it and were no longer able to function....oh, and my point was I can steal your smell and brake into your computer, along with every one else, and have so many stolen credit card numbers that I won't know which one to use.
