Cash
Carry useful denominations, not a visible roll
Small businesses, buses, markets, parking, tips, and rural stops may be easier with cash. Ask your bank for smaller US-dollar notes when practical, split cash between secure places, and avoid relying on large bills for a low-value purchase. Count change before leaving the counter without displaying your full travel budget.
Cards and ATMs
Use supervised machines and reject surprise conversion
Prefer ATMs inside a bank, shopping center, hotel, or staffed business. Inspect the slot and keypad, cover the PIN, keep the receipt, and review transactions. If an ATM or terminal offers to convert the charge into your home currency, compare that rate with your card issuer’s terms rather than accepting automatically.
Bitcoin
Optional payment, never the only backup
A business may accept a Bitcoin wallet, may use a different service, or may prefer dollars or cards. Ask before ordering, confirm the currency and amount on your own screen, understand network or conversion fees, and do not hand an unlocked wallet to another person. Current Canadian advice specifically flags card, ATM, and Bitcoin e-wallet fraud as risks.
Tipping
Check the bill before adding anything
Tips vary by service. Look for an included service charge, ask when the bill is unclear, and tip voluntarily for attentive table service, guides, drivers, or hotel help. Keep a few small notes rather than expecting every person to break a large bill.
