Travel essentials

Money & ATMs

Cash vs card vs e-wallet by country, ATM-skimming risk by district, and the practical money strategy for adult-travel contexts in Asia. The headline rule across the region: carry cash, leave surplus cards at the hotel, set hard nightly spend limits in advance.

The bank-flag risk

Foreign-card ATM withdrawals in nightlife districts at 03:00 trigger fraud-flag holds on your card from most issuers. The card freeze can then ruin the rest of the trip. Mitigation: travel-notify your bank before departure, and split spend across two cards from different issuers so a freeze on one doesn't lock you out entirely.

Thailand

Thai baht (THB)

Cash / card mix: Cash dominant in nightlife districts; card accepted in hotels, malls, supermarkets, mid-tier restaurants. Foreign-card transaction fees ~THB 220 per ATM withdrawal (regulated; the same across all banks).
ATM skimming risk: High in Patpong, Soi Cowboy, Nana Plaza (Bangkok); Walking Street (Pattaya); Bangla Road (Phuket). Use ATMs inside Bangkok Bank, Kasikorn, or SCB branches during business hours; avoid freestanding tourist-strip machines.
Card-cloning risk in venues: Documented; venue-card-machine cloning is the principal vector. Use cash in unposted-price bars. If a venue insists on card and the bill is contested, dispute via the card issuer immediately.
E-wallets: PromptPay (QR-based, requires local bank account) is dominant for locals; foreigners mostly cash. TrueMoney and Rabbit LINE Pay are alternatives.

Philippines

Philippine peso (PHP)

Cash / card mix: Cash dominant outside Metro Manila; cards accepted in malls and chain establishments. ATM withdrawal fees ~PHP 250.
ATM skimming risk: P. Burgos (Manila), Fields Avenue (Angeles) — skimming documented. Use BPI, BDO, Metrobank branch ATMs.
Card-cloning risk in venues: Documented; bar-fine venues and 'short-time' hotel card terminals are typical risk surfaces.
E-wallets: GCash (dominant), Maya (formerly PayMaya), GrabPay. GCash works with foreign passport ID + Philippine SIM.

Vietnam

Vietnamese dong (VND)

Cash / card mix: Cash dominant; cards accepted in hotels and chain establishments. Bills are large in face value (100,000 dong, 200,000 dong, 500,000 dong) — colour-similar; count carefully.
ATM skimming risk: Bui Vien (HCMC), Pham Ngu Lao (HCMC backpacker area), Tay Ho (Hanoi expat area). Use Vietcombank, BIDV, Techcombank ATMs in branch.
Card-cloning risk in venues: Documented; KTV-venue card machines are the principal risk surface.
E-wallets: MoMo (dominant), ZaloPay, ViettelPay. Foreigners can register MoMo with passport ID.

Indonesia

Indonesian rupiah (IDR)

Cash / card mix: Mixed; cash dominant in nightlife and small establishments, card accepted in malls and hotels. ATM withdrawal limits vary sharply by bank (typically IDR 1.5-3M per transaction).
ATM skimming risk: Kuta and Seminyak (Bali) — methanol-poisoning-adjacent risk amplified by sometimes-skimmed ATMs around bars. Use BCA, Mandiri, BNI branch ATMs.
Card-cloning risk in venues: Documented in Bali tourist zones; spa-venue card terminals are a recurring vector.
E-wallets: GoPay (Gojek), OVO, DANA, ShopeePay. Foreigners can register with passport ID at a Gojek office.

Japan

Japanese yen (JPY)

Cash / card mix: Cash dominant in fuzoku contexts. Major hotels and chain restaurants take card. Many bars in Kabukicho and Susukino are cash-only by design. 7-Eleven and Family Mart ATMs accept foreign cards reliably 24/7 (the recommended approach).
ATM skimming risk: Lower than the rest of the region. Bottakuri-bar card cloning is the principal risk rather than freestanding ATMs.
Card-cloning risk in venues: Concentrated in unposted-price bottakuri bars in Kabukicho, Roppongi, Susukino, Nakasu. The standard defence is: cash only in unposted-price contexts; never present a card in a venue you haven't already paid in.
E-wallets: PayPay (dominant), Rakuten Pay, LINE Pay. Foreign-issued cards work via Apple Pay / Google Pay in major chains. IC cards (Suica, Pasmo, ICOCA) work in convenience stores as well as transit.

Cambodia

US dollar (USD) primarily; Cambodian riel (KHR) for change under $1

Cash / card mix: USD dominant in Phnom Penh and Siem Reap; cards accepted in mid-tier hotels and restaurants. ATMs dispense USD and KHR. Riel is functionally small-change.
ATM skimming risk: Riverside and Pub Street (Siem Reap), Daun Penh (Phnom Penh). Use Acleda Bank, ABA Bank, Canadia Bank branch ATMs. Older bills (pre-2013 USD) may be refused — bring crisp notes.
Card-cloning risk in venues: Documented; smaller venue card terminals are the principal vector.
E-wallets: ABA Mobile, Wing, Pi Pay. USD-denominated.

South Korea

South Korean won (KRW)

Cash / card mix: Card dominant; cash works but unusual. Foreign cards work in major establishments. Smaller older businesses and outdoor markets often cash-only. KB, Shinhan, Hana, Woori ATMs reliable.
ATM skimming risk: Lower than Southeast Asia. The principal money risk is room-salon and condition-meeting bill padding rather than ATM skimming.
Card-cloning risk in venues: Documented in Itaewon and Hongdae but at lower frequency than the region.
E-wallets: KakaoPay (utterly dominant), Naver Pay, Toss. T-money card for transit. Most require Korean phone number + bank account so visitors typically can't register.

Taiwan

New Taiwan dollar (TWD)

Cash / card mix: Mixed; card and EasyCard for transit and convenience stores, cash for smaller establishments. ATMs at 7-Eleven (Cathay, CTBC) and inside bank branches accept foreign cards reliably.
ATM skimming risk: Lower than most of the region; freestanding skimming is rare in Taiwan.
Card-cloning risk in venues: Rare; KTV bill-padding is the principal money risk rather than card-data theft.
E-wallets: LINE Pay, JKO Pay, Taiwan Pay. EasyCard works across transit, convenience stores, taxis (some).

Singapore

Singapore dollar (SGD)

Cash / card mix: Card and e-wallet dominant. Cash works but increasingly unnecessary. ATMs at DBS, OCBC, UOB, Citi all accept foreign cards.
ATM skimming risk: Among the lowest in the region; freestanding-ATM skimming is rare.
Card-cloning risk in venues: Very rare; SPF Anti-Scam Centre prosecutes aggressively when reported.
E-wallets: PayNow (QR-based, requires local bank account or PayNow-compatible foreign account), GrabPay, fave. Visitors can use Apple Pay / Google Pay with foreign cards almost everywhere.

Cash / card mix: Card, Octopus, AlipayHK, WeChat Pay all dominant. Cash works. ATMs (HSBC, Hang Seng, Standard Chartered, BoC HK) reliable.
