Payments in Argentina: Cards, Pesos and QR

What a foreign card converts at now

Visa's Argentina page still describes a rate for foreign cards slightly below the MEP financial dollar, but its worked example dates from December 2022. September's posted figures sit lower. The card processor Payway was showing a foreign-card quote of 1,436.35 pesos to the dollar, dated 17 September 2026, and Visa's public calculator estimated 1,447.51 for a purchase on 25 September. On 28 September the MEP rate stood at 1,549.60.81097

So don't budget on the MEP number. The rate that counts is the one on your statement, and it can arrive late: American Express says its adjustment for cards issued abroad can take up to two billing cycles to appear. Compare that final figure, fees included, with what the same dollars would fetch in cash.11

QR codes, and why local wallets want a DNI

Under central bank rules, any interoperable wallet can pay any merchant QR, whatever logo is printed on it, by moving money out of a local bank or payment account. Opening one of those accounts is the obstacle. Mercado Pago's sign-up starts by asking for a DNI or CUIT, and MODO asks for your DNI before checking your identity with your bank.11213

A sticker with no card machine beside it is legal. Shops must accept debit cards for purchases of 100 pesos or more, but a shop that takes QR payments is exempt. Asking "¿Puedo pagar con tarjeta?" before you order saves an argument at the end. Where there's a Mercado Pago Point terminal, foreign credit cards are on its price list.414

A wallet registered abroad reaches those codes only through a local partner. The central bank opened that route on 5 May 2023, at the financial dollar rate. WanderWallet is built to scan them.2

Pesos cost something to get

The street premium that once made cash dollars worth carrying in bulk has gone. Argentina has floated the peso inside a central bank band since 11 April 2025. On 28 September 2026 the informal blue market bought dollars at 1,545 pesos, a shade under MEP, while the official bank buying price was 1,495. Both sat above the card quotes posted that month. Canada's advice, updated 24 September 2026, says to use official exchange bureaus and warns that some taxi drivers swap good notes for counterfeits.376

Western Union can beat the street, mostly on a promotion. On 23 September 2026 its US calculator turned a US$100 debit-card transfer into 159,900 pesos for cash pickup, with a US$17.99 fee crossed out. With that fee charged, the same pesos would have cost US$117.99, about 1,355 to the dollar and worse than a bank counter.15

ATMs are the expensive habit. The same Canadian advice notes low limits per withdrawal and per day for foreign bank cards and warns of substantial service charges, so small and frequent withdrawals multiply the cost. It also suggests indoor machines in hotels or supermarkets, and none after dark.6

How you pay can change the price

Card surcharges and cash discounts have arithmetic behind them. Mercado Pago's price list for its Point terminals, in force since 6 March 2026, charges a merchant between 5.90% and 6.29% plus VAT for an instantly settled credit-card sale, depending on the province. That's about double the debit rate. It adds 3% more when the credit card is foreign.14

The hotel is where the card wins outright. Registered accommodation drops the 21% VAT on the room, and on breakfast when it's included, if you live abroad and pay by a card issued abroad or a transfer from a foreign bank. The desk will ask for your foreign passport and the Migraciones entry record. Pay in pesos cash and you pay the tax.5

If a terminal or ATM offers to bill you in dollars, euros or pounds, Visa says that conversion carries its own exchange rate and extra charges, which must be shown on screen and receipt. Choose pesos, and the conversion stays with your card network and bank.16
