I've been waiting for someone to do this!
RFID tags embedded in chips $25 and up speed the cashing-out process, they do not have to ask you what table you were playing at, or call the pit to verify that you won the chips (to thwart attempts to cash stolen or purloined chips). The chips are placed on a sensor at the cashier's cage and presumably are matched with the table to which the chips were issued.
Also probably lets them track play more accurately, too. Which is generally not a good thing
