I find very likely Netflix or Amazon will be one of the first companies to support this in June now.
This was made initially to replace old school automatic debit for phone/electricity/etc bills, but it will support all services.
In Brazil, installments with credit cards are also super common... Basically when you put a credit card on any website or buy on a store, you can just choose to pay in 12x.
Well, they will add in September Pix Installments as well.
