They are not yet commonplace, they are still being developed. See this 2005 National Geographic article: http://news.nationalgeographic.com/news/2005/01/0126_050126_dnabarcode.html http://news.nationalgeographic.com/news/2005/01/0126_050126_... I can't seem to find too much details on how it might work other than the fact that it looks at a specific region of DNA that is common between a lot of eukaryotic species.
