How to switch fiat into ETN withouy a bank account

Hi Guys.
I would like to get some clarity on something.

If the Idea of ETN is to target the un banked.
How do theyv lan to allow the unbanked to switch their Fiat into ETN.

For people with Bank accounts its simple.
We do an EFT into a Luno account and we convert the Fiat into Crypto.

But if you dont have a bank account (unbanked)
You can probably do a cash payment at a bank teller.

But unless you know about Luno. How do you switch fiat into crypto.

Does the ETN team have functionality to allow Fiat to crypto?
