I doubt he has an accomplice. I think he's intimately familiar with the RFID system, including having had direct access to the actual one being used on Stones Live (per his connection to them that was observed on Linkedin), and enabled a multiplexing debug feature to send his phone a stream of every card being read.

It could be pretty independant from the main system too. They could wireshark the system's network connections to see if any rogue data is being sent and find nothing.

But, what if the data is coming directly from the RFID readers? Depending on which boards they're using to read the rfid cards it could be a simple bluetooth broadcast that his phone picks up. His phone could constantly scan for bluetooth signals -- it wouldn't even need to make an actual bluetooth connection, the card data could be embedded in the advertising signal for anyone who knew the schema to pickup.

I was thinking that he could encode the already read card data in a modulation of the RFID transponder itself. If the signal were randomised then it would just look like a noisy power supply or something?

There were some hands where he made weird bluff and his hole card in graphics changed after the opponent folded. (so his hand changed from air to very strong hand) Someone said it was a bug in RFID but it happened only to him and not constantly.

I think he has an accomplice. Either someone working at the casino or with remote access to casino computers.

I actually think the "changing cards" situations were the stream employees seeing the action and finding it so implausible that he was playing a given hand that way, and inadvertently gaslighting everyone by overwriting the graphics based on their assumptions. So they weren't necessarily complicit, but were sort of forced to cover for him because they couldn't say "Hm, maybe he's just cheating" to explain the insane moves hew as making.

That doesn't make sense at all. There is no reason for them to change the card if they don't have a proof that graphics are wrong.
