Over at http://www.gamingfloor.com/ I found this article about a Chinese couple passing fake "tokens". http://www.expatica.com/source/site_article.asp?subchannel_id=81&story_id=20163&name=Couple+cheated+at+roulette+with+fake+tokens

GamingFloor added that these were chips and jetons. No info if the "Chinese couple" were visiting from Asia somewheres or just whittling fakes on their own or ...? How long before the fake RFID chips start appearing I wonder.
