ZD3000 web authentification best practice

unknown

Hello,

I am using a ZD3000 with multiple R700 to deploy WiFi to
large public events, I would like to ask each client to enter some data
and store those for later reporting.

More specific, I want the
user to enter their name, address, email and phone number ( validate
this with a SMS by using a gateway ), after those steps are completed
the user should have wifi access. I looked into Guest Access and doesn't
seems to be what I need because the user cannot self register and I am
not sure how to retrieve the data for reporting.

The other option
was Web Authentication or WISPr but at this point it is not clear to
me. I would like to use a MySQL server to store the users information so
they can easily be exported into any format.

At this point I don't really know the direction to follow and research, any advice would be really helpful.

Thanks !
Mihail.
