Hi Onyekachi,
Yes you can prevent users from creating new applications. This is part of the PICC Master Key setting. Please keep in mind, if you select AID=000000 and authenticate with key #0 it is the PICC Master Key and if AID!=000000 it is the Application Master Key.
This is coded as part of the ChangeKeySettings() command. You can set options for “configuration is changeable yes/no”, “CreateApplication/DeleteApplication is permitted only with PICC Master Key authentication”, “Successful PICC Master Key authentication is required for GatApplications() and GetKeySettings()” etc.
