My friend, @jesterfunhouse, graciously gave me a new Insider Connected kit last night. I've been having fun already collecting the achievements, even though I wasn't planning on buying one ever.
I bought the coin door mount and waiting on that. What I'm doing now is moving the reader from game to game. I have network cables connected in each pin , so I open the coin door and plug in the reader. No big deal, just me playing and easy to reach in with my phone to scan. Plus I don't have to re-scan when playing games after game.
I had enough spare 16GB cards to install in each game. But of course I only have the single wifi dongle that was included in the kit. So that sucks having to move it to each game and re-enter wifi password, etc.
Anyway, found this AWESOME deal on a 5-pack of the CanaKit Raspberry Pi WiFi Wireless Adapter/Dongles. Now it makes it simple to move the reader itself from game to game. I probably won't even mount it and keep it in the coin door because I remove one cable and that's it.
$35!!! Seven packs left.
