When you pay with a dual-function card at the POS, before confirming the transaction, you will be asked if you want to use it as debit or credit. The same option appears when you withdraw money at an ATM, using the same PIN for both functions.
In Brazil, almost all credit cards are dual-function credit/debit and also BNPL. At the POS, choosing debit deducts the amount from your current account, while choosing credit then it will ask you if you want to pay the full amount or to select the number of installments (e.g., 3x, 6x, 12x) without interest, similar to Monzo Flex or Virgin Money Slyce.
The advantage of this system is that it reduces the number of cards you need to carry by half and doubles the number of cards you can add to Apple Pay. I was surprised to find that most countries I visited do not offer dual-function cards, including the UK, U.S., and most European countries, the only exception was Spain, which also offers dual-function cards.
That is really not a good card. It took me way to long to realise how it was spelling “Money”. It is just a mess. Probably my least favourite card, and I normally like the cards for kids accounts for being a bit more unique.
