How RFID cheating works?
I made a separate thread about my suspicion that this method is being employed in a poker room which I frequent. But I think the topic deserves a separate thread which is related to the topic and not coupled with my personal situation.
It's a blessing that there was a detailed presentation on the topic at Def Con in Las Vegas in 2016 and I am attaching a video of that presentation right here so you can hear from the hardware and software experts who sleuthed it all out.

In short, it works like this.
The hardware involves an infrared reader which is embedded into a variety of devices such as a smart phone or a car key. This is coupled with a deck of cards of the same brand which is used at the venue in question. The cards are marked on their edge with bar coding which is obviously invisible to the human eye. The software can be coupled with a voice or hepatic device in the form of a tiny earpiece which is used to communicate the relevant information to the player in a manner which is not detectable to anyone else.
Contrary to what opinionated people articulated in the other read, an RFID reader is capable of reading the order of cards in a stacked deck so if the user provides the number of people at a table, the outcome of the hand is discernible as soon as the cards are cut and can be communicated to the player in the order of finish at the instant the cards are cut.
The human thing which is required is for a card room employee to make sure the marked deck is put into play with their player collaborator.
A system like this was recently documented with a confession from a card room employee in Houston and casino operators caught the illicit activity on film as well as the culprit in possession of an RFID reading device.

There were a lot of people in the other thread who represented expertise that they clearly they did not possess. I suggest watching the video presentation in the link above before repeating that.

It doesn't take an expert to understand that RFID and bar codes are two different things.
RFID= Radio frequency ID- Like the chip you use to tap and pay with a credit card. It's like a miniature antenna that broadcasts over short distances to a receiving device.
Bar code= A visible pattern like they use on items at the grocery store. It's then scanned with an optical reader.
Both can be used on playing cards, but RFID readers do not scan bar codes.

Please watch the above video before commenting.
I don't have time to read all your links and watch a bunch of pointless videos. AI explanation:
"RFID readers do not work with barcodes, as they are different technologies. RFID readers are designed to read RFID tags using radio waves, while barcode scanners specifically read printed barcodes that require line of sight.
Compatibility of RFID Readers with Barcodes
Understanding RFID and Barcode Technologies
RFID (Radio-Frequency Identification) and barcodes are both used for tracking and identifying items, but they operate differently. RFID uses radio waves to communicate with tags, while barcodes rely on optical scanning of printed lines.
Can RFID Readers Read Barcodes?
RFID Readers: Primarily designed to read RFID tags, they do not have the capability to read barcodes directly. RFID readers communicate with RFID tags using radio waves, which is a different technology from the optical scanning used for barcodes.
Barcode Scanners: These devices are specifically built to read barcodes. They require a direct line of sight to scan each barcode individually.
Using Both Technologies Together
While RFID readers cannot read barcodes, businesses often use both systems in tandem. This combination allows for enhanced tracking capabilities:
RFID for Bulk Scanning: RFID can scan multiple tags simultaneously without needing line of sight, making it efficient for inventory management.
Barcodes for Precision: Barcodes can provide precise tracking for individual items, especially in retail environments where customers interact with products directly.
Conclusion
RFID readers and barcode scanners serve different purposes and cannot interchangeably read each other's formats. However, they can complement each other effectively in various applications, enhancing overall inventory management and tracking efficiency."
FYI - Please watch the video which thoroughly documents how this stuff works before commenting in ways which might be contradicted by the documentation.
You are just wrong. The DefCon video is all about infrared reader. It has nothing to do with RFID. Until you learn the difference you will continue posting and sounding like the idiot you are.
The DEFCON presentation, which was well discussed here in 2016, has nothing to do with RFID.What evidence do you have or have you shared that supports your claim a RFID reader can determine the order of a deck of cards.Not an optical barcode reader. Not that somehow a RFID reader was used to cheat in some not described way. Actual support that RFID can determine the exact order
OK .. it seems I was ignorant of the difference between RFID and infrared.
Cheating is serious but Bro is worried about this and there’s probably some super quick dealer skimming pots.
Pay attention to what matters and stop with the James Bond stuff, esp in MTTs(?) lol.
Sounds like OP was on a wild goose chase over a sun-runner, however, as tech advances, I can see RFID being compromised.
Apps downloaded to smart glasses can detect radio waves, problem right now is they must be within a few feet to read the wave.
You wouldn't need to introduce a deck. After an hour of play + exposed cards, the App could've stored each cards' ID wave.
This wouldn't help with knowing flops/turns/rivs, but it could allow the cheater to detect his opponent's 2 hole cards. (If cards were spread out, not stacked.)
The video is difficult to listen to since the guys (and gal) native language is not English.
The cards are marked with infrared and the device uses LED to read the infrared markings.
So why are we talking about RFID and bar codes?
If a player can get a deck into a game then fumble around with an infrared reader, a cell phone that works as a cell phone but also has an infrared reader and computer in it or a car key or whatever and not be caught, they deserve to win all the money.
Just keep your heads up and keep a keen eye on all players at your table is my suggestion.

Agree this has nothing to do with RFID. I think OP finally gets that but it took awhile.
As to barcodes, that is in reality or at least effectively exactly what the video describes. A barcode is printed in infrared ink on the edges of a deck. The device, a special phone, is the barcode reader and calculator.
