Looking for tech opinions / answers about RFID imbedded chips ...
It appears that the RFID imbedded "passive" chips inside some casino chips (Fontainebleau, made by Abbiati, for instance) operate at 13.56 MHz. Correct so far? Do ALL imbedded RIFD casino chips use that frequency, or other frequencies too?

As for reading the RFID chips, It seems that the cashiers cage has some sort of reader to verify legit chips. And some table games are outfitted with readers that can do "inventory" of total chip values placed in a betting square. (Ex: 10 x $100 chips, reads as $1000 bet, etc.) Maybe more data collection and analysis too, such as figuring a player's average bet per hour & "theoretical" value for purposes of determining comp value to offer. Still correct, so far?

Now, regarding READING the RFID, I see that RFID readers can be purchased on Amazon and elsewhere. Different makes & models -- handheld (connecting to a cellphone), connected to a computer, standalone RFID readers, etc. Used in a variety of applications to include, inventory scanning, card readers for entry, etc., pet ID imbedded chips, and lots more, in addition to scanning casino chip RFIDs.

RFID readers start at $25 price range and go up from there. But if I buy one and attempt to read some RFID chips I have, is there $25 worth of fun there? Do I just get a "beep" sound, or an "OK" light, or a 10-digit random number? Not that much fun. On the other hand, if I get a readout that says "Fontainebleau $100" (AND other casino names, denominations, etc. too), that would be kinda fun.

In the past, I've bought a UV light (to look at UV marks on chips) and a magnifying glass (to look at security "dots" and other markings). So I'm willing to spend $25 for a RFID reader if it creates a little fun. Just hoping that it wouldn't be a complete bust. What do you think? Any other RFID casino chip pioneers out there?

Two reference links, for those interested -- an Amazon RFID reader for $24.90. Also, a write-up on RFID in casino applications by a company called GAO RFID Inc.
