RFID sensor for reading pot size... (2 Viewers)

[bgritt]

Hello! Apologies if this is the wrong category for this topic, please let me know if so. I just found this forum and I've gone down a few of the interesting threads here on RFID tech in poker tables. I'm working on a DIY option for my own home games so that I can transmit real time chip data between the live game and other players who are interacting virtually. My question pertains to RFID range capabilities and poker chip reading. Is there anyone here who has gone down this path and found the best RFID reader solution to read a stack of chips placed near the center of the table? Maybe something with a range of around 10 inches from the center to create a diameter of 20 inches of readable area and a chip stack 10 inches high? I'm pretty new to RFID technology and the latest tech, so hoping someone who has been more immersed in this topic can provide a starting point. Thanks for any advice.

@eightyWon might be the one to speak with. He is working on a pretty cool RFID project at the moment.

Following. This is a dream of mine too.

Aside from the anti collision problem, you will have a very bad coupling between your big board antenna and each very small tag antennas. i would say it requires testing but i’m pessimistic.

I'm pessimistic too as a DIY project because the level of complexity seems like an order of magnitude above what I'm working on.

There are issues like collision detection (as @LaBestiole pointed out), read range, and just the amount of time it takes to read any significant number of tags.

I'm sure RFID chips are successfully being used in casino settings and that's the angle I'd approach from if I were to try and DIY it. What equipment are casinos, the WSOP, etc., using? I'd learn as much as I could about that gear and go from there. Publicly available info seems sparse just from a quick search.
