You will get paid via your bank account. You need to register a bank account with Google Play Mechanism. After that, you will receive a confirmation amount via email. Enter this amount to verify your Google account, then you can receive money via this bank account. You will receive it once a month. Also, you can check the payment history as well.
I haven’t setup this kind of accounts before, but I think you are overthinking the issue. I believe you need to open a bank account, you will get a number related to this bank account (google IBAN). And when signing up In google/apple form you will be asked for this number or any other security code. In fact, you will need to enter your details not only to get paid, but to pay apple’s 99$/year fee, and google’s one time 25$ fee, before you can actually publish your app on either platforms.
