District positions

I some questions/comments:
Does the online registration system require a payment for all applications?
(A person applying for a district position who is already in a unit should be “free”)
What forms of payment are accepted (Credit/Debit Card, check , cash)?
I just went through two Cub recruiting at elementary schools NOT all of the parents of our cubs have Credit/Debit Cards) see some discussions in “https://discussions.scouting.org/t/transferring-scouts-between-councils-via-my-scouting”. These could be issues on why online applications do not work for some councils or in some cases.
