Every travel horror story about money in China — the traveler whose card was blocked at the Shanghai airport ATM, the family that couldn't link a foreign card to WeChat Pay, the couple who arrived with only home currency and a broken credit card — has one thing in common: it was preventable. The good news is that none of these require hours of work. The tasks below take about 30 minutes of active effort if you do them in one sitting, spread over the week before your trip. We have organized them by timeline so you know exactly when to tackle each one.

2 WEEKS BEFORE DEPARTURE
- ✅ Notify your bank(s) of your travel dates and destinations. Call the number on the back of every card you plan to use. Tell them explicitly: dates (departure and return), countries you are visiting (not just China — include connecting transit countries), and that you will be using mobile payment apps (Alipay, WeChat Pay). Ask them to note this in your account. See our bank notification guide for a sample script.
- ✅ Confirm daily ATM withdrawal and purchase limits. Ask what your daily ATM limit is and request an increase if needed (many banks set defaults of $300–$500/day which may be too low). Also confirm daily purchase limits and whether these reset at midnight local time or midnight at home.
- ✅ Find and save your bank's international customer support number. This is often different from the 1-800 number on your card. Write it down in two places: a notes app on your phone (offline), and a piece of paper in your wallet or luggage. Memorize it if you can. When you're in a noisy Shanghai taxi trying to unblock a declined card, you will need it.
- ✅ Check foreign transaction fees on every card. Find out which cards charge 0% foreign transaction fees, which charge 1–3%, and which charge ATM withdrawal fees of $X plus Y%. You may find one card is cheaper for purchases and another is cheaper for ATM withdrawals — that's normal. See our card fee guide for what to look for.
- ✅ Identify your "primary" and "backup" cards. Designate one credit card for hotel deposits and large purchases, one debit card for ATM withdrawals, and one "emergency" card you keep locked in the hotel safe. Make sure these are from different banks — if one bank flags your activity and freezes your account, you still have access to the other.
- ✅ Verify your cards will not expire mid-trip. Check the expiration date on every card you are carrying. If any card expires within 6 months of your return date, consider getting a replacement before departure or carrying a different card. Some merchants — especially international hotels — will refuse cards with less than 3 months left.
1 WEEK BEFORE DEPARTURE
- ✅ Back up your phones and download offline maps. Before you install Alipay and WeChat Pay, make sure your phone is backed up. China's internet environment is unique, and you will want offline access to maps (Google Maps needs a VPN, so download a China-friendly alternative), your bank numbers, your passport photo, and scanned copies of your cards.
- ✅ Install and set up Alipay with your foreign phone number. Download from the official App Store or Google Play. Register, complete passport verification, and link your Visa or Mastercard. Test it with a small purchase or at least confirm the app shows your card as "active" before you fly. See our step-by-step Alipay guide.
- ✅ Install and set up WeChat Pay as well. Register a WeChat account with your foreign phone number, complete Wallet activation with passport verification, and link a card. Even if you think you'll primarily use Alipay, having WeChat Pay set up takes 15 minutes and gives you a critical backup. See the full WeChat Pay setup guide.
- ✅ Verify SMS international roaming works on your phone. WeChat, Alipay and your bank all use SMS for two-factor authentication. If your home SIM cannot receive international SMS, you will be locked out of everything. Test by sending an SMS to your own international number while still on home soil.
- ✅ Calculate how much yuan you should exchange before departure. Most travelers get enough local currency for 2–3 days of expenses — roughly USD 100–150 in yuan, depending on your budget. Exchange a small amount at home so you can pay for your first taxi, snack and metro ride in China without hunting for an ATM at midnight. See our cash calculator guide.
- ✅ Research where ATMs and currency exchange centers are at your arrival airport. Know which terminal they are in, whether they use the Plus/Cirrus networks your cards are on, and whether they have English interfaces. Most major Chinese airports have several options, but some are hidden or behind security.
- ✅ Download your bank's mobile app and log in. Make sure you can access your account balance, recent transactions and online support from the app. Test that biometric login (fingerprint, Face ID) works — you may not remember your password under stress.
NIGHT BEFORE DEPARTURE
- ✅ Take photos or scans of every card and save them offline. Front and back of each credit and debit card, your passport's photo page, your driver's license, and your travel insurance card. Save these to an encrypted notes app, a cloud service, and email them to yourself. If your wallet is stolen, having these speeds up card cancellation by hours.
- ✅ Decide where to store each payment method during travel. Use different bags and pockets: one card in your daily wallet (for frequent use), one card in your carry-on bag's hidden pocket (backup), cash split between a money belt and your hotel safe, one backup card left at the hotel safe and only accessed if both others fail. Do not carry all your payment methods in one place.
- ✅ Make sure you have a small amount of yuan in hand. Not a large stack — just enough for a taxi from the airport, a bottle of water at the convenience store, and any unexpected small payment at your hotel upon arrival. 500–1,000 yuan (≈ USD 70–140) is a comfortable starting amount.
- ✅ Check your bank accounts for any holds or alerts. Log into each account and make sure there are no unexplained pending transactions, fraud alerts or security prompts that might trigger while you're abroad. If anything looks off, call your bank before you leave.
- ✅ Save your hotel's address and phone number (in Chinese characters). Not just in English — you need Chinese characters for taxi drivers and metro ticket machines that don't accept English text. Have this saved on your phone and written down on paper.
- ✅ Put a note in your passport or luggage with your bank numbers and emergency contacts. A simple folded paper with: the international phone numbers for each bank, your home bank branch number, and a contact person back home who knows your itinerary. You don't want this visible to everyone, but if something happens to your phone, having it in your physical documents is critical.
- ✅ Set a "stop-loss" alert with your bank if available. Many banks let you set alerts for transactions over a certain amount, transactions in specific categories, or daily spending totals. If your card gets stolen, you want to know within minutes — not hours — that something unusual is happening.
- ✅ Take a deep breath and confirm you have all methods working. Quick final check: Alipay works, WeChat Pay works, main credit card is in your wallet, backup credit card is in your carry-on, debit card is with you, cash is split, bank numbers are saved. You are ready to fly.
What Happens If You Skip These Steps?
We get emails every week from visitors who skipped these and hit problems. Here is what typically goes wrong:
No bank notification: You try to pay for your hotel with a credit card on day one. Your bank sees a charge from a Shanghai hotel, flags it as fraud, and declines it. Now you're standing at the front desk with no working card, potentially no cash yet, and you need to call the bank from an international number while they run through security questions you can barely answer. This is the #1 travel payment complaint we see.
No mobile payment setup before departure: You arrive in Beijing, try to download Alipay, and discover your home SIM can't receive international SMS for verification. You can't complete setup. You don't have cash yet. You have one card that the small restaurant near your hotel refuses. You are stranded for a meal and a metro ride. This scenario is surprisingly common.
All cards in one wallet: You get pickpocketed in a Shanghai subway station. Your credit card, debit card, cash reserve and ID are all gone. You have no backup payment method for the rest of the trip, and you have to spend days canceling cards. Splitting payment methods across bags is free and takes 30 seconds.
Frequently Asked Questions
How far in advance should I notify my bank?
Most banks recommend 1–2 weeks before departure. This gives their fraud monitoring systems time to note your travel dates and countries. Waiting until the day before means the notification may not be fully processed, and you risk card declines on your very first transactions abroad.
Should I set up mobile payment apps before leaving home?
Absolutely. Setting up Alipay and WeChat Pay before departure lets you complete passport verification and foreign card linking while you still have reliable home SIM access for SMS codes. Waiting until arrival risks roaming or SIM card problems that derail the setup.
What is the most important backup payment method?
A credit card with no foreign transaction fee kept separate from your other cards. Use it for hotel deposits and large purchases. Pair it with a debit card for ATM withdrawals and a modest cash reserve — three layers of protection.
How much cash to exchange before departure?
Enough yuan for 2–3 days of basic expenses — roughly USD 100–150 equivalent. The rest can be withdrawn from ATMs or exchanged at hotels in China, which often offer better rates than home exchange offices.
