QR codes connect many everyday tasks in China, from paying and ordering food to unlocking shared bikes.
Order a coffee in China and the cashier may point to a small square code instead of a card machine. Scanning can feel unfamiliar at first, but the language is simple and highly reusable. Once you recognise 扫一扫, you will understand a small action that keeps daily life moving.
Where You Will Meet QR Codes
A printed code lets even a small vendor accept mobile payment.
For payment, you may scan a merchant’s code and enter the amount, or show your own payment code for the cashier to scan. Both directions are common. At restaurants, a code on the table often opens the menu and may handle ordering and payment too. Codes also appear on shared bicycles, tickets, lockers, parcel machines and some building entrances.
They spread quickly partly because printed codes are inexpensive: a small shop can display one without installing a card terminal. Large mobile apps then made the same scanning habit useful across many services.
Useful Chinese Words and Phrases
- 二维码QR code
- 扫码to scan a code
- 付款to make a payment
- 点餐to order food
- 现金cash
请扫这个码。
Qǐng sǎo zhège mǎ.
Please scan this code.
在哪儿扫码？
Zài nǎr sǎomǎ?
Where do I scan?
扫一扫 repeats the verb 扫, “to scan”. This makes the action sound quick and casual, rather like “give it a scan”.
A Short Restaurant Scenario
In many restaurants, scanning the table code opens the menu.
A: 请问在哪儿点餐？
Qǐngwèn zài nǎr diǎncān?
Excuse me, where do I order?
B: 扫一下桌子上的二维码就可以。
Sǎo yíxià zhuōzi shang de èrwéimǎ jiù kěyǐ.
Just scan the QR code on the table.
A: 付款也在上面吗？
Fùkuǎn yě zài shàngmiàn ma?
Do I pay there as well?
B: 对，点完直接付款。
Duì, diǎn wán zhíjiē fùkuǎn.
Yes, pay there after ordering.
A common misunderstanding is to assume that a table code is only for paying. In some restaurants, staff expect you to order through it and may not bring a paper menu automatically. Ask 有纸质菜单吗？ (Yǒu zhǐzhì càidān ma?, “Do you have a paper menu?”) if you prefer one.
What Should a Visitor Do?
Set up a supported payment app before travelling, because registration, identity checks and card verification are easier to solve at home. Current official guidance says overseas visitors can register for Alipay or Weixin Pay and link supported international cards; acceptance, limits and fees can vary, and the card issuer must approve the link. Carry some renminbi and a second payment option in case your phone, connection or card fails.
Never scan an unexpected code sent by a stranger. At a counter, look for the code staff indicate and confirm the amount before approving payment.
Digital Culture Spotlight: China’s Official Payment Guide
The same familiar action also unlocks many shared bicycles.
China’s State Council publishes an official guide to working and living in China, including current information on mobile payments, international cards and cash. Check it shortly before departure because supported cards, charges and payment-app rules can change.
二维码 literally means “two-dimensional code”: 二维 means “two-dimensional”, while 码 means “code”.
Final Takeaway
In China, scanning is less a novelty than an ordinary social gesture linking payment, food and transport. Learn 扫一扫, ask where to scan when unsure, and keep a backup way to pay.
