The whole purchase amount plus interest is taken from the credit card limit and every month you are charged for those installments.
If you don't pay in full your statement, you pay regular Brazilian credit card interest rates (i.e. very high) on top of the BNPL interest rates.
Some stores that have high cash flow may opt to not explicitly charge interest, opting to discount the price if you pay in full or charging the same price no matter whether paying in full or in 12 installments.
It's important to note that the Brazilian BNPL scheme is enabled by the credit card acquirers, so there's a high degree of integration.
