This is Part 2 of the Poker series, see Recording Poker Games for the initial setup.
What would be the best way to track the cards being played?
I could train a machine learning model or use an existing one? See Playing-Cards-Computer-Vision from @awrd2019. Not sure how much work this would be and how accurate the results are.
The next idea was RFID Playing cards, I got a link for Luna NFC/RFID Cards by Andras Barthazi and thought £21.99 for a pack isn't bad, but I'd miss read:
- Blank face (6 cards): £21.99
- Poker face (52 + 2 cards): £104.99
- Blank face (54 cards): £104.99
Checking other sites I found one a little cheaper in RFID PLAYING CARD DECK, ISO15693 £93.00 GBP.
So why don't I just buy some NFC / RFID stickers and put them on an existing pack of playing cards? It might make them harder to shuffle and easier to see a marked card but for an inital POC it'll be cheaper.

Only £8.99 for 50, that's much better, albeit I need 52 and I'll have to stick them all on and program them all, but that's the fun part!
Next I need a reader/writer, which I'm sure I saw in the ADVENTURE KIT 2 $197.00 I'd bought.
1x RFID reader and Keychain
Create your own unique ID card and be able to read the data from it. Allowing just those with access keys in.
There's a video and board layout on the course:
Next problem is I'll need a board to connect to them, so that then adds more wires, there doesn't seem to be a nice compact way like with the camera.
I also need to test what the pickup area is, will I only need one per pocket? Will The Board only need one too? Once I've tested I'll feed back with the results.
I can then create a local API that I can post the cards too, which in turn will update the screen.
Having access to what cards are available I can also calculate rudimentary pot odds. Add them to the screen too.
The actual pot will be harder - mic with voice recognition? Weigh the table? RFID on each chip? Let's solve one problem at a time.
All this hardware setup it starting to get messy, my thoughts here are to create my own custom table, I can then hide all the parts in custom fitting areas. If the wood is thin enough the devices should be able to pick up the cards. Plus then I have an excuse to do some woodwork :).
