Money is one of the easiest things to get right in 旧金山 — and one of the easiest to quietly overpay on. Here's how to pay smart in 旧金山, 美国: the currency, cards versus cash, what to budget, transport payments and tipping, with the local specifics just an in-app question away.
The currency & how to pay
美元（USD）；餐厅小费一般为 15–20%，并留意菜单是否包含服务费。 In short, lead with a card that charges no foreign transaction fees for most spending — it gives you the best exchange rate and the most protection — and keep a little local cash for markets, tips and the small places cards don't reach. Whether you're at a shop terminal or an ATM in 旧金山, always choose to be charged in the local currency, never your home currency: the 'home currency' option builds in a markup that's almost always worse than your card's own rate.
- Lead with a no-foreign-transaction-fee card for most spending
- Carry some local cash for markets, tips and small vendors
- Always pay in the local currency in 旧金山, never your home currency
What things cost in 旧金山
As a rough guide, plan around $120–$300+ 每日（经济至中档；高档酒店和餐饮费用更高） in 旧金山 — adjust up for boutique hotels and fine dining, down for hostels, street food and free sights. Set a daily number before you go and track it loosely so a few splurges don't quietly blow the budget. Many of the best experiences here — wandering neighborhoods, markets and viewpoints — cost little or nothing.

Getting around & paying for transport
公共交通（Muni 公交、轻轨、有轨电车）以及连接区域的 BART 可到达大多数目的地；顺风车和自行车适合短途，停车费用昂贵且交通有时拥堵。许多中心街区非常适合步行，但需预料陡峭的坡道。 Wherever you can, use the official transport payment method — a transit card, pass or contactless tap — rather than paying a premium in cash, and agree fares or use a meter or a rideshare app for taxis to avoid being overcharged.

Tipping in 旧金山
Tipping customs vary a lot between countries, so it's worth knowing the local norm in 美国 before you arrive rather than assuming your home habit. As a sensible default, round up or leave a small token for good service where tipping is customary, and never feel pressured where it isn't. For the exact, up-to-date tipping etiquette in 旧金山 — restaurants, taxis, hotels and guides — just ask Mike in the app.

Money-smart in 旧金山
A few habits keep more money in your pocket in 旧金山: withdraw cash from bank ATMs (not airport or tourist-strip exchange kiosks, which have the worst rates), take out larger amounts less often, decline any machine's offer to 'convert' to your home currency, and keep a backup card stored separately in case one is lost or blocked.
