Cash, card or phone pay: what works by region

Start with the card. A no-foreign-transaction-fee card is the single biggest saving; the difference between 0% and 3% on a USD 3,000 trip is USD 90. If you do not have one, a multi-currency account with a linked card gives you the same effect and often a better exchange rate. Order it at least three weeks before departure so it arrives and activates.

Add the phone layer. Load the same card, or a second one, into Apple Pay or Google Pay. On Android and iPhone this works at any contactless terminal, which is most terminals in card-first regions. For China, set up Alipay or WeChat Pay before you fly and link an international card; both accept foreign cards for tourist use, but the setup needs your home number and a passport check.

Then the cash layer. Order a small amount of the destination currency from your bank or a currency desk before you leave, enough for the first day: a taxi, a SIM card, a meal. Change the rest locally at banks or ATMs rather than airport kiosks, which usually carry the worst rates. Carry notes in two places. If you want a hard-currency reserve, check first whether USD or EUR notes are actually accepted where you are going and what rate you would get; in many places local currency is the only reliable option.

Card purchases abroad usually cost you nothing beyond the exchange rate if your card has no foreign transaction fee. Cards that do charge typically add around 3% in the US and often 2.5–3% in the UK, Canada and Australia, plus the network's conversion margin, which is baked into the rate you see. A no-fee card removes the first part; the margin remains but is usually small. These are 2026 estimates — your issuer's fee schedule is the only number that binds.

ATM withdrawals are where costs stack. Your home bank may charge a flat fee, the foreign ATM may charge another, and some banks add a percentage. Foreign ATM fees commonly run from zero to a few dollars or the local equivalent, and some machines cap each withdrawal. Withdrawing the maximum each time is the cheapest habit. Check your own bank's and the local ATM operator's terms before you rely on a figure.

Phone payments cost the same as the underlying card, because the wallet just passes the charge through. Where a wallet saves money is in China and Southeast Asia, where QR payment avoids cash-handling and sometimes unlocks small discounts. Setup time is the real cost: budget 20–30 minutes at home to add a card to a wallet, and longer for Alipay or WeChat Pay if the verification needs a passport photo.

Dynamic currency conversion is the most common way travellers lose money without noticing. The terminal or ATM offers to charge you in your home currency; the rate it uses is set by the merchant's bank, not yours, and is usually worse than the local-currency price. Always choose the local currency, even when the screen makes the home-currency number look convenient.

Cash-only pockets exist inside card-first countries. In Germany and Austria many small restaurants, bakeries and taxis are reported to take cash only, and some shops set a card minimum. In Japan, convenience stores and chain hotels take cards, but small restaurants, temples and rural buses often do not; a loaded IC card such as Suica or ICOCA covers trains, buses and many vending machines. In the US, cash is still expected for tips in some situations, though card tips are now standard at most counters.

Phone-only pockets exist too. In China, Alipay and WeChat Pay are the default and some stalls no longer keep change; foreign cards work for tourist payments but the setup is not instant and needs doing before you arrive. In Sweden and Denmark, some businesses are effectively cashless and may refuse large notes. In India, UPI QR codes are everywhere but need a local bank account, so visitors fall back on cash and cards.

Two more traps: cards that block foreign use until you confirm a text to your home number, and phone wallets that stop working when your phone battery dies. Carry a physical card and a small power bank.

Each method wins in a different situation. Cash is universal but risky to carry and poor value to obtain. Card is cheap and fast but fails at small vendors and in cash-first countries. Phone is the fastest at the counter but depends on battery, network and a wallet that accepts your card.

The practical rule is to lead with the method the region prefers and keep the other two as backup. That way you are never the traveller holding up a queue, and never the one walking to a hotel because the taxi takes nothing you have.
