Quoted from Pinfatuated:

I suggest that the Stern Connected thing add a Convention setting that automatically logs players out after the game. Normally they're is going to be a line for a game. If not, then a lucky player with no line can just scan in before each game.
I had it happen multiple times to me that when I walked up to a game and pressed the Start button for the appropriate number of players, it would Start more games than intended because the prior players had Logged In the Connected thing and not logged out and so the first Start press would add 2-4 players and any additional presses would add more players unless at 4 already.
Additionally, the game should forget any scanned in player that doesn't start a game within a few (1-3?) seconds. I saw people walking around to empty games and scan in on as many games as possible without playing so that when others walked up they would likely get credit for those plays - for whatever benefit or honors that might impart, if any.
Having just found out about the Insider Connected stuff and being exposed to it, I see some interesting potential in it. I agree with the person that said Stern should sell the hardware at cost or less. I think broad adoption of the tech is likely to boost profits and industry health through increased customer engagement and therefore location play and game purchases.
If it was cheap enough, I would install it in 6-12 games, primarily for use at parties to track high scores, award prizes, and set goals to increase play and player interaction. At $200 a game, I am unlikely to retrofit any games.
