Root Cause
Vietnam is largely a cash economy in Vietnamese dong (VND). Cards are accepted at hotels, malls, and many city restaurants, but street vendors, small shops, rural areas, and markets are cash-only. Foreigners can open accounts but generally need a residence/work document; tourists should rely on cash and ATMs.
genericWorkarounds
-
90% success Carry VND cash for daily spending and use ATMs/cards mainly at hotels, malls, and larger restaurants.
Withdraw VND from bank ATMs (watch per-transaction limits and fees); keep small notes for street vendors, taxis, and markets.

82% success Use a no-foreign-fee debit card and reputable bank ATMs to minimise withdrawal costs.
Prefer ATMs attached to major banks; avoid dynamic currency conversion (always choose to be charged in VND).
Dead Ends
Common approaches that don't work:
-
Travel Vietnam with only cards, expecting to tap everywhere like at home
60% fail
A large share of Vietnamese commerce - street food, markets, local transport, rural shops - is cash-only in VND. Card-only travelers get stuck at the majority of small vendors.
-
Open a Vietnamese bank account as a tourist to handle local payments
70% fail
Banks generally require a residence card or work documentation to open an account; tourists are usually declined. Local digital wallets (e.g., MoMo) also require a Vietnamese bank account.
