Quoted from MikeS:It's not worth the cost for home but if you buy one game with it included you can use the scanner to setup home team for the rest of your Spike 2 games.
This is what I did on a older LCD game. Added the WIFI dongle and connected the QR reader from GZ with a long cable to setup. Then use home team to use it without the scanner.
Only downside is if you forget to start with home team you cant scan in later.
