Here’s the answer before you read another paragraph: bring some cash, get one fee-free ATM card sorted, and don’t bother chasing e-wallet access. Vietnam runs on a mix of all three, but they’re not used equally, and knowing which one to reach for saves you real money.
The Quick Answer
None of the three works everywhere on its own. Here’s the honest breakdown:
- Cash: still essential.
Street food, markets, small taxis, and rural areas run on it. Always have some on you.
- Card: works well in cities.
Hotels, malls, and chain restaurants take it. Watch the fees, they add up quietly.
- E-wallet: built for locals, not tourists.
MoMo and ZaloPay are everywhere, but most require a Vietnamese phone number and bank account. Don’t plan your trip around them.
Vietnamese Dong 101
Vietnamese dong comes in big numbers, and locals shortcut it in conversation. If someone quotes a coffee as “thirty,” they mean 30,000 VND, not 30. Get comfortable dropping the last three zeros in your head and prices stop feeling absurd.
As of mid-[YY], 1 USD converts to roughly 26,000 to 26,400 VND, though it moves day to day, so check a live rate close to your trip instead of trusting an old blog post.
Pro tip: The easiest way to lose money by accident isn’t a scam, it’s mixing up notes. The 500,000 VND and the 20,000 VND bills are both blue and similar in size. Check the printed number in the corner, not just the color, especially at night.
Cash: When You Actually Need It
- Street food, markets, and small local restaurants
- Small taxis, motorbike taxis, and city buses
- Rural areas and small towns outside the main tourist circuit
- Tips, which are appreciated but never expected
Some of this is airport-specific too. Buses out of Tan Son Nhat, for example, only take cash, as our guide to getting from Ho Chi Minh Airport to District 1 covers in more detail.
Cards: Where They Work, and the Traps
Cards work fine in hotels, malls, supermarkets, and chain restaurants, and contactless tap-to-pay is spreading fast in the bigger cities. The trap is what happens when you tap: some terminals ask if you want to pay in VND or in your home currency.
Pro tip: Always choose VND. Paying in your home currency triggers dynamic currency conversion, which quietly applies a worse exchange rate than your card’s own network would give you.
A few smaller businesses also add a 2 to 3 percent card surcharge to cover their processing fees. It’s usually posted near the register. If a bill looks off, ask before you tap.
ATMs: Which Ones to Actually Use
| ATM | Fee for Foreign Cards | Typical Withdrawal Limit |
|---|---|---|
| VPBank | Usually free | Up to 10,000,000 VND |
| Most other banks (Vietcombank, Techcombank, BIDV) | ~22,000-66,000 VND per withdrawal | 2,000,000-3,000,000 VND |
| Airport ATMs | Often on the higher end | Varies by machine |
Fees change without much notice, so treat this as a starting point and check the screen before you confirm any withdrawal, it will show the fee upfront. Withdraw larger amounts less often rather than making several small withdrawals, since the fee is charged per transaction, not per dong.
Pro tip: Skip the airport ATM for anything beyond your first taxi fare. Better rates and lower fees are almost always a short walk away once you’re in the city.

E-Wallets: The Reality Check
MoMo, ZaloPay, and VNPay are genuinely everywhere in Vietnam, QR codes are taped to market stalls and coffee counters across every city. The problem for tourists is signup: most of these apps need a Vietnamese phone number and a linked local bank account to fully activate, neither of which you’ll have on a short trip.
There’s a narrow exception. A handful of nationalities can pay Vietnamese QR codes directly through their own home banking app via a cross-border system, but it only covers a short list of countries and isn’t something to count on.
Pro tip: Don’t plan your trip around Vietnamese e-wallets. If you happen to get one working, treat it as a bonus, not a backup plan.
How Much Cash Should You Actually Carry?
A comfortable range for most trips is enough small bills for a day or two of street food, transport, and tips, topped up from an ATM as you go rather than carrying a large stack from day one. If you’re bringing in a larger sum, know the line: amounts over USD 5,000 or 15,000,000 VND need to be declared at customs.
Our Vietnam Customs Rules guide covers exactly how that works and what happens if you go over.
Quick Questions, Straight Answers
Should I exchange money before I land?
A small amount is fine for peace of mind, but airport counters and home-country exchange desks both tend to offer weaker rates than an ATM withdrawal once you’re in Vietnam.
Is USD accepted in Vietnam?
Rarely, and only informally in a few tourist spots. Treat Vietnam as a VND-only country and you won’t run into problems.
What’s the best type of card to bring?
One with no foreign transaction fee and a low FX margin. It won’t help with the local ATM’s own fee, but it removes the second layer of cost on every card swipe.
Can I use Apple Pay or Google Pay?
Yes, wherever a terminal already accepts contactless Visa or Mastercard, since your phone is just tapping through the same card network. It won’t unlock local QR-code payments on its own.
Get the Money Sorted, Then Relax
None of this needs to be complicated. Land with a little cash, know which ATM to use, and let cards handle the rest. The moment this actually matters most is the first half hour after you touch down, before you’ve withdrawn anything or found a working SIM, which is exactly when a rough immigration queue makes everything feel harder than it needs to be.
Fast Track Vietnam‘s agents meet you before the immigration hall, walk you through a priority lane, and get you to the arrivals hall while the regular queue is still moving slowly, so you can go sort your cash and SIM without the added stress.
