Following the Chips in Wynn's New Casino

Posted by CmdrTaco on from the hey-steve-comp-me-a-suite dept.

ctwxman writes "As Steve Wynn gets set to open his new Las Vegas casino, something new hits the tables: RFID encoded chips they report that "The fancy new chips look just like regular ones, only they contain radio devices that signal secret serial numbers. Special equipment linked to the casino's computer systems and placed throughout the property will identify legitimate chips and detect fakes" " " Having stayed pretty much everywhere else cool on the strip, I'm sure I'll try the Wynn out soon after it opens, but I think I'll be cashing out my chips before I leave the casino. It makes me nervous knowing I could be unwittingly scanned by others after I leave the floor. Of course, this added inconvenience may save me a fortune in blackjack losses!

    The range over which you can read RFID information in any sort of portable (ie: non-obvious) fashion is limited to a few inches. In fact, tuning the damn things so they'll read at (say: 4 or 5) inches is hard.

    The readers that are designed for doorways can do roughly 2 feet, but they're huge and very very obvious - they're designed for store entrances, where they make you walk through the "gates" to get in/out of the store. You can't miss a 4-foot (max) separated row of columns covering all the exits...

    RFID works by the reader exciting a sympathetic response in the tag (which is itself unpowered, though it rectifies the incoming RF energy to self-power), this response modifies the reader's waveform signal, overlaying an incredibly weak (roughly 1% of the incident waveform) signal on top. It is this weak modification to the reader's signal that has to be extracted and deconstructed into a bitstream.

    Speaking as one whom RFID has tried, it's not an easy task to get any significant distance between tag and reader, and IM(NS :-)HO the likelihood of being randomly snooped on wherever you go is damn small. Almost flying-pig small. Our asset management system aimed for a 6" separation between tag and reader, and we didn't care about being obvious though there were size constraints for the reader (had to fit in a 1U box). Getting repeatable results proved very difficult with the units we had.

    Aside: London Underground introduced an RFID-based system for block-purchase of tickets, promising it would read your "ticket" in your bag/pocket as you passed by. This claim was dropped on introduction, and they now advise you to swipe the reader with your tag as you go by...

      RFID tried you out? How did that go? Did it hurt?

      Considering the space already available to install cameras, cabling, and God only knows what else above the ceiling, wouldn't it be easy to include large transmitters in the ceiling?

      Better yet, install a semi-large one (a little smaller than your doorway-size variety) in each table. Doesn't matter if you see all 10 tables "light up" when Joe Gambler walks by them, you only need to get 2-3 hits before you can retrace his steps.

      It's sorta like facial recognition in that you can build up a track of where Joe Gambler went during his entire time at the site.

      But it's better -- because you can sort those tracks by dollar amount. What would it be worth to a casino's marketing department to know which path certain groups customers walk after losing all their chips (or after doubling their chips!), and reorganizing their floors (placing bank machines along the most likely route for the losers, and slot machines or other tables along the way to the cashier's cage for the winners) accordingly?

      If you were really clever, you could even have hustlers on the floor. Guy wins $1000 at a $25 Blackjack table? Cute chick comes over and offers him a drink on the way to the cashier's. Asks him how he did. Points out the conveniently-located row of $100 tables that somehow always have to be walked around before he can get to the cashier's.

      As we progress, running a casino will become more and more like playing SimAnt. (Then you can sell an extension the technology to the government to play with the rest of society, and it gets to be a lot more fun, to say nothing of more profitable :)

  3. I wonder... by Iphtashu+Fitz · · Score: 5, Interesting

    If I took some chips out of the casino, rendered the RFID tags useless with a magnet (or whatever it takes), then went back and requested payment, would they refuse to pay?

    I can potentially imagine the big stink that would arise if RFID tags stopped working in valid chips for some reason. Suppose you were playing blackjack and won a ton of money, went straight to the cashier, and they refused to pay because the RFID tags weren't responding. I can imagine lawsuits would spring up pretty darned quickly.
