Hi,

someone has a single code (no username/password) method for a captive 
portal pay-per-use wireless hot spot?
Tha idea:
A user buy a card with a code with a bonus time of 60 minutes. Connect 
to the wife using captive portal and surf the web.
Disconnect, connect,... only for a total of 60 minutes. After that the 
code is unavaible.
Authentication by radius :-)

Bye
