Does this system require casinos to re-rack or will existing (e.g. H&C with plain edges) work? Great article in the latest CC>CC magazine but, for black jack players, a bit scary don't you think? Tracks not only how much you bet but exactly what you do with each hand and can quickly tell if you are counting cards. Feels like the big brother to me but then, as a recovering black jack player gone to poker, guess I don't really care--
