Playing on a Table or Computer in a Tournament

It shouldn't be "too difficult" making an RFID sensor BG board, I guess.

Reading stacks will not be the problem anyway, unless you have so big problems with reading neighbor pieces that you turn the power way down.

It shouldn't be too expensive either (well everything is relative, but I'd recon the hardware needed could be purchased at $100-$200). The passive RFID tags that needs to go into the pieces are virtually free (a full set of 32 would run at no more than $5-$10). You could do with maybe one reader, but more likely 2, 4 or 6 readers. Then you'd need an array of antennas that you could switch, to read the different pips. Depending on antenna design (and power setting), you'd be reading what's on one pip, or what's on 3 pips, or something like that... :-) I think that would be the biggest challenge (messing around with reader/antenna design and layout to optimize the reading of tags). But like Xavier writes, a lot of issues can be solved in the software, if you know the dice rolls!

You would know each individual piece, not just black/white, so going from position A to position B you would know exactly what piece was moved from where to where, which could be helpful in determining a position. Again that depends on the chosen reader/antenna layout, but in some scenarios it could be useful. (Eg. if you find it difficult to determine where a certain piece is placed, you could take a look at where it came from, and what was rolled).

Using a DGT clock (that already has the built in "ping" for software position readers when plunged), would be the easy way to go.

But even more easy for a first version, would be a tablet app clock, that could easily be programmed to make such pings, and maybe also to handle the doubling cube and dice rolls in the initial stages...
