Why Do You Need Mobile Payment When Heading North?
The mainland is basically a "cashless society": restaurants, supermarkets, ride-hailing, convenience stores, and even street stalls all use QR code payments. Bringing only cash will lead to a lot of trouble:
- Many merchants don't accept cash or can't make change
- Some restaurants and food delivery platforms only accept mobile payments
- Only with mobile payments can you get coupons, discounts, and membership points
💡 In short: when spending in the north, having either WeChat Pay or Alipay is basically a necessity.
WeChat Pay HK Card Linking Guide
The easiest way for Hong Kong users is to use WeChat Pay HK (WeChat Pay Hong Kong version), which allows you to link a Hong Kong credit card or Faster Payment System (FPS) directly:
- In the WeChat app, tap "Me" → "Services" → activate WeChat Pay HK
- Link a Hong Kong credit card / bank account (supports most Hong Kong banks)
- Complete real-name verification (using your Hong Kong ID; required for some features)
- When spending in Shenzhen, show merchants your payment QR code, or scan the merchant's collection QR code
Another method is to use the mainland version of WeChat Pay, which requires linking a mainland bank account or mainland phone number. This is suitable for users who frequently head north or plan to stay long-term.
Alipay (AlipayHK / Mainland Version) Guide
Alipay also has a Hong Kong version, AlipayHK, which can also link Hong Kong credit cards:
- Download the AlipayHK app and register with a Hong Kong phone number
- Link a Hong Kong credit card / bank account and complete real-name verification
- Scan to pay at mainland merchants (AlipayHK already supports the mainland merchant network)
If you want to use the mainland version of Alipay (with the most complete features, including Meituan, DiDi, etc.), you'll need a mainland phone number + a mainland bank account. This is why we always say "phone card + bank account" are the three essentials for living in the north.
Is Cash Still Usable?
Although the mainland promotes mobile payments, cash is still legally accepted in Shenzhen — it's just that some merchants find making change troublesome. Recommendations:
- Carry a small amount of RMB cash for emergencies (e.g., ¥200-500)
- Large shopping malls, hotels, and chain stores usually accept cash
- For currency exchange, you can use Hong Kong money changers or mainland banks — watch out for exchange rates and fees
⚠️ If a merchant refuses to accept cash, you can politely insist, or patronize a nearby shop instead. But for your own convenience, it's recommended to mainly use mobile payments.
Money-Saving Spending Tips
- Watch for exchange rate deals: Some credit cards / e-wallets offer preferential exchange rates or rebates when spending in the north
- Use coupons: Meituan and Dianping frequently have group-buying deals, which can only be purchased with mobile payments
- Enable small-amount password-free payments: Scanning to pay for meals and shopping becomes much faster
- Handling refunds: When paying with mobile payments, refunds are automatically returned to your account, which is more convenient than cash
