How does OCR work in live casino? What the documents show
OCR in live casino, traced from the ranking explainers to a roulette patent filing and a security guide: what is read from the camera, and for which games.
On the explainers that rank, OCR in live casino is camera software that reads a dealt card’s rank and suit from the video feed and passes it to the game as data. For roulette, the one primary method this desk read samples coloured pocket regions and the ball’s position on video, rather than reading numerals.
This is an evergreen explainer. On 8 October 2026 this desk read two roulette patent filings, NCC Group’s guide to testing online roulette, and the rank-1 explainer. The encoder it feeds is covered in what a game control unit is.
How does OCR work in live casino card games?
Telemedia Magazine’s June 2024 explainer: cameras capture the card as it is drawn, OCR picks out suit, number and symbol, and the data reaches the player’s screen in real time. It extends OCR to dice and the roulette wheel; it cites no supplier.
How does live roulette capture the winning number?
US20030060263A1, a Technical Casino Services filing, puts a camera beside the wheel. Video is sampled where the coloured pocket-number region passes, then where the ball would sit; if the ball is in that pocket, the number is output. That is colour and position sampling, not character reading.
TCS John Huxley Australia’s WO2011060486A1 claims ball-in-rim and no-more-bets signals, the latter when the ball slows to a predetermined angular velocity. It covers monitoring a live roulette table; neither filing shows what any current studio uses.
NCC Group’s guide separates on-live (a real wheel shown live), virtual (PRNG) and live automatic (simulated physics) roulette. The text read does not say how an on-live result is captured.
What each source describes, by game type
| Game | Capture method described | Source | What it does not say |
|---|---|---|---|
| Cards | Camera capture; OCR reads suit, number, symbol | Telemedia, 2024 | No supplier or document |
| Roulette result | Video sampling of pocket colour and ball position | US20030060263A1 | Filing, not deployment |
| Roulette timing | Ball-in-rim and no-more-bets signals | WO2011060486A1 | Table monitoring, not result capture |
| Dice | Dice images converted to data | Telemedia | No method given |
| Money wheel | Nothing described | None of the pages read | Open question |
Did OCR replace RFID?
BusinessCloud’s 2022 partner content says so, without a source; this desk read no supplier text on RFID. Wider kit list: what equipment a studio needs.
FAQ
Why can OCR be used in live dealer games?
Because a dealt card carries printed rank and suit marks a camera can see. Telemedia says cameras capture each card and OCR picks out suit, number and symbol. It cites no supplier, so a given studio’s method is a vendor question.
How do live dealer online casinos recognize cards?
On the explainers read, a camera captures the card as dealt and software reads suit and number into data. BusinessCloud’s 2022 partner piece adds a database cross-check and an unsourced claim that OCR replaced RFID. This desk read no supplier document on card capture.
How do physical cards become digital data?
The explainers describe a chain: camera, recognition software, then a game control unit encoding the result for the online game. The documents this desk read give a full capture method only for roulette, where a filing samples colour and ball position on video.
