Credit or Debit? What a Brazilian ATM Is Really Asking

Two layers run through this, and they are not interchangeable: what a rule requires, and what a network publishes about its own machines. Here they diverge, so both appear.

What the screen is sorting

Brazilian regulation never sorts payment cards into credit, debit and prepaid. It sorts them by the account sitting behind the card.

Resolution BCB 150/2021, article 9, classifies a payment arrangement by the user's relationship with the institution, and gives four options: a prepaid payment account, a postpaid payment account, a deposit account, or a relacionamento eventual — an eventual relationship, where the customer holds no account there at all.

The debit function lives inside the third one. A conta de depósito — a deposit account — is where the money comes from when you pay or withdraw on debit, and it is the account, not the word "debit", that the norm names.

Which changes what the machine is doing. It is not asking what your plastic is. It is asking which relationship the transaction runs on, and the ones on offer are Brazilian.

Where the word "function" even comes from

One place in Brazilian regulation defines função, and it is not a consumer rule. It is a reporting form: Doc 6334, the specification the central bank imposes on acquirers for the card data they file.

The definition is short and decisive. The function is "the form of payment chosen by the cardholder and accepted by the accredited merchant", and three values are allowed, to be filed in capitals: D for débito, C for crédito, E for pré-pago.

Two things follow. The choice is defined as yours, with the merchant accepting it: the regulator describes who picks, it does not order anyone to ask. And it is written about a shop, not a cash machine, so nothing in it tells a terminal what to display.

At the counter the practice can invert that: one acquirer publishes that the shop selects credit or debit before the terminal reaches your hand. But the counter is its own subject.

At a cash machine, a withdrawal is not one service

The ATM has a harder reason to ask than a shop does. Banco24Horas, one of the independent networks here, publishes what each participating institution enables. There a withdrawal is not one service with a variable attached: it is a list of separately named ones — Saque conta corrente, Saque conta poupança, Saque cartão de crédito, and more for payroll-credit and app-code withdrawals. Checking, savings or credit is not a detail bolted on; it is which withdrawal you asked for.

Some entries in that catalog are not banks at all, but card brands:

That is what the network publishes on those rails, not what a foreign card is shown: it names the brand, never the country of issue. And Elo shows that three is no law here — it publishes five.

A Brazilian rule depends on the answer too. Free-withdrawal entitlements are counted per account type — more from a checking account than from a savings one — so a machine that never asked could not apply them.

Your card has a category. It is not one of the buttons.

The regulation does name what you are holding. Article 10 of the same resolution classifies an arrangement by territorial reach, and the second option is cross-border: an instrument issued in the country for use abroad, or issued abroad for use here. Your card is a defined class, not an edge case the system tolerates.

The gap opens one level down. The central bank's list of authorized arrangements — 43 of them, under its November 4, 2025 stamp — carries only two purposes: purchase, on 27 entries, and transfer, on 16. No withdrawal purpose exists. The arrangement filing a foreign card against a deposit account is a purchase arrangement, which is the counter, not the cash machine.

The reporting closes the loop from the other end. Doc 6334 sorts each transaction by function, brand, product, modality, capture form, segment and installment count, and by nothing else: across the whole specification "exterior" and "estrangeiro" appear zero times, "país" once, inside a merchant-category description. Nothing asks where the card was issued.

That is narrower than it sounds. The authorized list splits domestic from cross-border in a column of its own, so Brazil does distinguish foreign cards. What the form settles is only that your transaction reaches the acceptance statistics as a debit or a credit like any other.

The screen nobody publishes

This is where the trail stops.

The same network that separates withdrawals by account type in its catalog also publishes three walkthroughs of how to take cash out — one dated September 28, 2020, two undated — and none has a step for choosing the account. They go from identify yourself, to PIN, to amount, to confirm. One company, one machine, two versions of whether the choice exists.

One screen element is committed to print: Banco24Horas states on its blog that its machines hold a physical ceiling of 20 notes per operation, and that the number appears on screen before you confirm. It is the only piece of a Brazilian ATM screen we found an operator willing to write down.

The closest thing to a published screen comes from a state bank. Caixa's official cardless-withdrawal booklet photographs real terminals, and they repay reading for the interface rather than the flow: "use os botões ao lado da tela" — the buttons beside the screen, not a touch surface — and an amount screen asking "QUANTO VOCÊ QUER SACAR?" over preset values that, the booklet warns, "may vary by time of day or by the number of banknotes available". Hence one terminal offering different options at different hours.

Not your flow, and we will not pretend otherwise: that is a withdrawal made with a CPF and a code from a Brazilian banking app, which a visitor does not have. What it establishes officially is the hardware and the language.

Portuguese, and no button for it

Every screen photographed in that booklet is in Portuguese, and none carries a language control. We could not find one Brazilian network, bank or terminal maker publishing whether its machines offer another language. That is not the same as a Portuguese-only network, and we are not writing it as one.

The silence is not for want of an audience. The same network runs an English page aimed at you, saying its devices are available "including with international cards" — a foreign reader, addressed in English, about a foreign card, with nothing said about the screen that card will meet. Its locator filters by the compact in-store unit, deposits, note sizes, opening hours and venue type; there is no filter for "takes my card", and the only language control on the page is the website's own PT/EN/ES switch.

One more crack: that English page names eight international brands accepted at the machines, while the service catalog on the same domain carries four. Only one of the two can be current, so we record the divergence rather than smooth it.

So the practical reading is plain. The button selects a Brazilian account relationship, your card carries a foreign one, and the mapping is made by your issuer and the brand — not by the screen. What the withdrawal costs and what to do when no route works come next.

What we could not verify

• The screen a foreign-issued card actually sees — the order, the labels, the button. We read the full Banco24Horas sitemap and its twelve likeliest blog posts, both Saque e Pague service pages and its help centre, Caixa's booklet, a Banco Mercantil walkthrough and the acquirer specification. Nobody publishes it; everything published assumes a Brazilian account.
• Whether any Brazilian ATM offers a language other than Portuguese. No network, bank or terminal maker publishes it, and the one official document showing real screens shows them all in Portuguese. Tourism blogs and expat forums claim otherwise; none is a source we accept.
• Whether a card withdrawal in Brazil lets you choose the notes. One operator publishes a screen step for exactly that — but only on a Pix withdrawal, which needs a Brazilian account. Nobody publishes the same for a card.
• How many foreign-card transactions Brazil sees, split by function. The count does not exist by design: the acquirers' form has no field for the country of issue. The sets that would carry it sit among five of ten central-bank open-data resources that returned HTTP 500 to us, while the other five answered on the same call signature.
