Money in Argentina: What You Actually Need to Know

Money is one of those things people worry about before coming to Argentina — and honestly, I understand why.

Exchange rates, cards and cash have changed quite a few times, which means a lot of advice online is simply outdated. So rather than giving you one exchange rate that may be wrong by the time you arrive, here are the things that are actually useful to know.

Cards

Cards are widely accepted in Mendoza, especially in the city and tourist areas. For most visitors, using a foreign card is the easiest option — but it isn’t always the cheapest.

Some restaurants and smaller businesses add a card surcharge, sometimes around 10%, to cover payment processing costs. Always ask if you’re unsure:

“¿Tiene recargo con tarjeta?”

If the terminal asks whether you want to pay in pesos or your home currency, choose pesos (ARS) and let your card provider handle the conversion.

And bring two cards if you can. You never know when one will decide to stop working.

What about the exchange rate on my foreign card?

This is where a lot of older travel advice gets confusing.

Argentina has had several different exchange rates in recent years, including the famous blue dollar, but the foreign-exchange system has changed significantly since 2025. The old advice you may find online about automatically looking for the blue rate is therefore not something I would rely on for a trip today.

Foreign Visa cards can still receive a preferential exchange rate for purchases in Argentina, and Visa currently lists this benefit for cards issued outside Argentina. The exact rate changes, so I would check your card provider shortly before travelling rather than planning your whole budget around a number you found on a blog.

The practical advice: bring your cards, check your bank’s fees and international-use settings, and don’t panic if you see ten different exchange rates mentioned on Google.

Cash & dollars

It’s still useful to have some cash with you, especially outside the city or at smaller businesses.

US dollars are the most useful foreign currency, and clean, undamaged notes are much easier to exchange or use. Bring a mix of denominations — large notes are great until you need to pay for something small.

You don’t need to arrive with your entire holiday budget in cash.

I would think of USD cash as a backup and another way of accessing your money, rather than something you need to carry around every day.

And don’t keep all your cash in one place. You don’t need to walk around Mendoza with your entire travel budget in your bag.

How much cash should I bring?

There isn’t one magic number because it depends on how long you’re staying and how you travel.

If you’re staying mainly in Mendoza city, using cards for hotels and restaurants and doing organised tours, you can get by with relatively little cash.

If you’re travelling to smaller towns, using local transport or staying somewhere more remote, having more pesos or USD available is useful.

My advice: have enough cash for the day, plus an emergency backup — not your entire holiday budget in your pocket.

Western Union

Western Union can be a very good option for getting pesos, and its exchange rate is often competitive. You can send money to yourself and collect it in pesos at a local branch.

Just check the current rate, fees and availability before sending a large amount. Some branches can also have queues or limited cash.

I wouldn’t send your entire holiday budget through Western Union before you arrive. Start with an amount you’re comfortable with and see how the process works.

Also remember that branch availability matters. A Western Union location showing online doesn’t necessarily mean it has unlimited cash available when you walk in.

ATMs

ATMs are available, but they wouldn’t be my first choice. Fees and withdrawal limits can make them expensive.

If you use one, check the current fee and limit and take out a larger amount rather than making several small withdrawals.

Your own bank may also charge you for the withdrawal, so check both sides of the transaction.

And if an ATM offers to convert the withdrawal into your home currency, be careful. In general, you want your own card issuer to handle the currency conversion rather than accepting an ATM’s conversion.

QR payments

You will see QR codes everywhere in Argentina.

Locals use digital wallets and bank apps constantly, and QR payments are a normal part of everyday life. Argentina’s payment system allows local wallets and banking apps to make payments through QR codes.

For visitors, however, it can be a little different.

Don’t assume that every QR code will work with your foreign banking app.

Some international wallets can process QR payments in Argentina, and foreign tourists can receive the same type of preferential exchange-rate treatment for eligible QR payments as for foreign cards. But whether it works depends on the wallet and how it is connected to the Argentine payment system.

So if you’re visiting from abroad, I would treat QR as a bonus payment option, not something you should rely on for your entire trip.

Cash discounts

It’s completely normal to ask:

“¿Hay descuento en efectivo?”

Some businesses offer a discount for cash, so it never hurts to ask.

Just compare the final price rather than assuming cash is always cheaper.

And remember: a cash discount isn’t worth carrying around a huge amount of money just to save a few pesos.

Tipping

Tipping is fairly relaxed in Argentina.

For restaurants, leaving around 10% is common when you are happy with the service, although there isn’t the same rigid tipping culture you may know from the US.

And unlike the old advice you’ll find online, many restaurants can now add the tip directly to your card payment.

If you’re a resident with an Argentine bank account, some places also allow tips through QR or bank transfer.

Cash is still perfectly fine too.

For other services — taxis, guides, drivers, hotel staff, etc. — tipping is generally discretionary rather than an obligation.

A few things visitors often get wrong

“I need to exchange all my money when I arrive.”

No.

You don’t need to convert your entire holiday budget on day one. Your spending situation may be different depending on whether you’re staying in the city, visiting wineries, travelling around the country or using cards most of the time.

“I found an old article with a better exchange rate.”

Be careful.

Argentina’s currency system has changed considerably, and old articles can make today’s trip sound much more complicated than it actually is. The BCRA changed the foreign-exchange regime substantially in 2025, including lifting major restrictions for individuals.

That’s exactly why I don’t put a daily exchange rate on this page.

Check the current situation shortly before you travel.

“I need to carry lots of cash.”

Also no.

Cards are useful in Mendoza, and having some cash as a backup is sensible. You don’t need to walk around with thousands of dollars in your handbag.

Before you fly

1. Bring two cards if possible.
2. Have some US dollars in clean notes.
3. Check current Western Union rates if you plan to use it.
4. Tell your bank you’re travelling if your bank requires travel notifications.
5. Check your card’s foreign transaction fees.
6. Make sure your cards are enabled for international payments.
7. Don’t rely on an exchange rate or price from an old blog post.
8. Keep a small amount of cash available for places where cards don’t work.

And most importantly:

Don’t spend your whole holiday chasing the perfect exchange rate.

Argentina’s money situation can look complicated from the outside, but you don’t need to become a currency trader before your holiday.

Use the payment method that makes sense for you, keep some cash as a backup, and go enjoy Argentina.
