 4. Launch the game, and check the amdaemon console for server startup messages
 5. Access the using one of the interfaces (see below), add a new server `http://<your-ip-address>:6070`, import your existing card (or create a new one) and start playing!
 
 ### Physical Cards
-AMNet 1.3 adds support for scanning physical cards on iOS devices. If you own a physical Aime/Banapass/e-Amusement/Suica card, you can scan it using the app and use it in-game.

+AMNet 1.3 adds support for scanning physical cards on iOS devices. If you own a physical AiMe/Banapass/e-Amusement/Suica card, you can scan it using the app and use it in-game.
+By changing the `useAimeDBForPhysicalCards` in segatools.ini, it is also possible to adjust the format of card numbers sent to the game:
 
-- `access` - This is the default and should be used if the game server is hosted locally.
-- `idm` - If the game server is hosted on a shared network (rinnet/aquadx.net/missless) use this option instead (cards that have been used on a cabinet connected to the same network should load correctly).
+- `0` - Default value, will send the 20-digit access code on the back of the card to the game and load the save data directly.
+- `1` - Send the card's IDm data to the game, and it will use the connected AiMeDB to retrieve a 20 digit code assigned to the card. This option should be used on shared networks to enable the same account data/profile as you would get on a physical cab.
 
 ## Interfaces
 AMNet can be used on most platforms, see below for options available for each platform:
