RFID chips.

Lately there has been rumours about a past posting team that were caught at the Wynn when they past posted a 1000$ chip below a 100$ on the third dozen. The alarm went off for the dealer when the 1000 $ chip suddenly arrived after the number has come out and the claimer of the 1000$ chip were arrested. I have searched the news archives without finding anything on the incident so i don`t know if it is only a rumour.
