Ask whomever you heard it from, because it's not true.

The simplest test example, adding a user and cleartext-password entry
to the top of /etc/raddb/users (or wherever your user file is), would
allow a user to authenticate to the NAS (i.e. login) with that
password. And if that NAS sends accounting packets, FR will record it,
and you can then use the accounting information to charge the user
later (i.e. postpaid).

To create a prepaid user, you need to return some limit attribute that
your NAS understands (i.e. Session-Timeout,
ChilliSpot-Max-Total-Octets, whatever) to limit how long that user can
be online. Usually that's done by using and configuring rlm_counter or
rlm_sqlcounter (see the docs and wiki for details).
