解説 二维码 in your Level:

At the A1 level, you only need to recognize '二维码' as a single object associated with your phone and scanning. You will see it everywhere in China. Think of it as the 'key' to doing anything. When you see a square pattern of black and white dots, that is a '二维码'. In simple sentences, you use it with '扫' (sǎo - scan) or '看' (kàn - look/see). For example, if a teacher or a friend shows you a QR code to add them on WeChat, they might say '扫我' (Scan me) or '这是二维码' (This is the QR code). You should learn to say '我要扫二维码' (I want to scan the QR code) when you need to pay for something or open a website. It is one of the most practical words you will learn in your first week of Chinese study because it is the primary way to interact with the environment. You don't need to worry about the 'two-dimensional' part of the name yet; just remember the three characters together: èr-wéi-mǎ. At this level, focus on the physical action of scanning and the visual recognition of the code on posters, tables, and screens. If you can point at a code and say '二维码', you are already doing great! You will also encounter it in the phrase '扫一扫' (sǎo yī sǎo), which is the label on many Chinese apps like WeChat and Alipay. This is the gateway to the digital life in China. Even at this early stage, understanding this word will help you feel much more independent when navigating stores and restaurants.

At the A2 level, you should start using '二维码' in more complete sentences and understand its different functions. You should know that '二维码' can be used for '支付' (zhī fù - payment), '点餐' (diǎn cān - ordering food), and '加好友' (jiā hǎo yǒu - adding friends). You will begin to notice that '二维码' is often the object of the sentence. For example, '请扫一下这个二维码' (Please scan this QR code). You should also be able to describe where the code is located, using prepositions like '上' (shàng - on) or '下' (xià - under). For instance, '桌子上的二维码' (The QR code on the table). At this level, you might also encounter the word in the context of taking the bus or subway, where you use a '乘车二维码' (chéng chē èr wéi mǎ - transit QR code). You should be able to ask questions like '哪里有二维码？' (Where is there a QR code?) or '我可以扫二维码吗？' (Can I scan the QR code?). You are also learning that '码' (mǎ) is the short form, often used in phrases like '扫码' (sǎo mǎ). Understanding this contraction is key for A2 learners as it appears in many signs and advertisements. You should also be able to handle simple problems, such as '我扫不出来二维码' (I can't scan the QR code) or '二维码太小了' (The QR code is too small). This level is about functional communication in daily life where the QR code is a tool for survival and convenience.

At the B1 level, you can discuss the '二维码' in the context of technology and daily habits. You should be able to explain how QR codes have changed life in China. For example, you can talk about the '无现金社会' (wú xiàn jīn shè huì - cashless society) and how the '二维码' is the core of this change. You will use more sophisticated verbs like '生成' (shēng chéng - to generate) and '识别' (shí bié - to recognize/identify). You might say, '这个软件可以自动生成二维码' (This software can automatically generate a QR code) or '我的手机无法识别这个模糊的二维码' (My phone cannot recognize this blurry QR code). You should also understand the difference between '静态二维码' (jìng tài - static) and '动态二维码' (dòng tài - dynamic), which is important for security and payments. At B1, you are expected to follow more complex instructions, such as '长按二维码识别' (Long-press the QR code to identify it) while using a mobile browser. You can also express opinions about the convenience or security of using QR codes. For example, '我觉得二维码支付非常方便，但也担心安全问题' (I think QR code payment is very convenient, but I also worry about security issues). You should be comfortable using '二维码' in various contexts: from business meetings (sharing contact info) to logistics (tracking packages). Your vocabulary surrounding the word should now include '扫描仪' (sǎo miáo yí - scanner) and '感应' (gǎn yìng - to sense/induction).

At the B2 level, you should be able to use '二维码' in professional and technical discussions. You can explain the technical difference between a '二维码' and a '条形码' (barcode) using terms like '维度' (wéi dù - dimension) and '存储容量' (cún chǔ róng liàng - storage capacity). You can discuss the impact of QR codes on the '零售业' (líng shòu yè - retail industry) or '物流业' (wù liú yè - logistics industry). You should be able to use the word in formal writing, such as a report on digital trends. For example, '二维码的普及极大地推动了中国移动支付的发展' (The popularization of QR codes has greatly promoted the development of mobile payments in China). You will also encounter the word in legal or security contexts, such as '诈骗二维码' (fraudulent QR codes) or '个人隐私' (gè rén yǐn sī - personal privacy). You should be able to give a short presentation on how to use QR codes for marketing, using phrases like '引流' (yǐn liú - to attract traffic) and '营销工具' (yíng xiāo gōng jù - marketing tool). At B2, your understanding of '二维码' extends beyond the physical object to its role as a data carrier. You can discuss how it facilitates 'O2O' (Online to Offline) commerce. You should also be familiar with the '二维码' ecosystem, including '小程序' (xiǎo chéng xù - mini programs) that are often accessed via scanning. Your ability to troubleshoot complex issues, such as '二维码纠错级别' (QR code error correction level), shows a high level of proficiency.

At the C1 level, you can engage in deep sociological or economic debates regarding the '二维码'. You might analyze how the '二维码' has contributed to the '数字鸿沟' (shù zì hóng gōu - digital divide), where elderly people who cannot use smartphones are excluded from services that require scanning a code. You can use the word in academic contexts, discussing its '编码算法' (biān mǎ suàn fǎ - encoding algorithm) or its '容错性' (róng cuò xìng - fault tolerance). You should be able to read and understand technical specifications or white papers about QR code standards in China. Your vocabulary will include terms like '矩阵式二维码' (matrix QR code) and '层级结构' (hierarchical structure). You can also discuss the cultural implications of the '二维码' in Chinese society, such as how it has changed the concept of '面子' (miàn zi - face) in social networking or the etiquette of '抢红包' (qiǎng hóng bāo - grabbing red envelopes) via QR codes. In a business context, you can discuss '二维码追溯系统' (QR code traceability systems) for food safety or supply chain management. You should be able to use the word fluently in any register, from extremely formal technical seminars to casual slang-filled conversations about the latest digital trends. You understand the nuances of how the '二维码' is integrated into '智慧城市' (zhì huì chéng shì - smart cities) and '物联网' (wù lián wǎng - Internet of Things).

二维码 30秒で

A two-dimensional matrix barcode (QR code) used for storing data and linking to URLs, ubiquitous in modern Chinese digital life.
Primarily used for mobile payments (Alipay/WeChat), adding social media contacts, and accessing digital services like restaurant menus.
Interacted with using the verb '扫' (sǎo - scan) or '出示' (chū shì - show), and can be either static or dynamic.
A symbol of China's transition to a cashless society and its mobile-first approach to technology and social interaction.

The term 二维码 (èr wéi mǎ) is the Chinese word for 'QR Code,' which literally translates to 'two-dimensional code' (二 èr = two, 维 wéi = dimension, 码 mǎ = code). In the context of modern China, this word represents far more than just a data storage format; it is the fundamental bridge between the physical and digital worlds. While QR codes were invented in Japan for the automotive industry, China has become the global leader in their everyday implementation, making the term 二维码 ubiquitous in daily speech and visual landscapes. You will encounter this word from the moment you step off a plane at a Chinese airport to the moment you order street food from a tiny stall in a rural village. It is the primary method for processing payments, identifying individuals, sharing social media profiles, and accessing digital services.

Technical Composition: The 'two-dimensional' aspect refers to the fact that data is encoded both horizontally and vertically, allowing it to hold significantly more information than a traditional one-dimensional barcode (条形码 tiáo xíng mǎ).

请扫描桌子上的二维码点餐。 (Please scan the QR code on the table to order food.)

In a practical sense, the word is almost always paired with specific verbs. The most common verb is 扫 (sǎo), meaning 'to scan.' You will frequently hear the phrase '扫个码' (sǎo gè mǎ), which is a casual way of saying 'scan the code.' Another common verb is 识别 (shí bié), meaning 'to identify' or 'to recognize,' often used in technical contexts when a phone's camera is processing the image. During the COVID-19 pandemic, the term became even more central to life with the '健康码' (jiàn kāng mǎ - health code), a specific type of QR code used to track health status. This period solidified the QR code's role as a mandatory digital identity marker in Chinese society.

Cultural Significance: In China, 'scanning the code' has replaced the physical exchange of business cards (名片 míng piàn). Instead of handing over a card, professionals will simply open their WeChat QR code for others to scan.

我加你微信吧，你出示一下二维码。 (Let me add you on WeChat; please show your QR code.)

Furthermore, the ubiquity of the 二维码 has led to a 'cashless society' phenomenon. From high-end shopping malls to elderly vendors selling vegetables in a wet market, the QR code is the standard payment interface. There are two main types of payment interactions: '主扫' (zhǔ sǎo), where the customer scans the merchant's static QR code, and '被扫' (bèi sǎo), where the merchant scans the customer's dynamic QR code displayed on their phone. Understanding the vocabulary surrounding these interactions is essential for anyone living in or visiting China. The technology has even extended into the realm of public transport, where '乘车码' (chéng chē mǎ - transit code) has largely replaced physical metro cards in major cities like Shanghai and Beijing.

这个二维码已经过期了，请刷新一下。 (This QR code has already expired; please refresh it.)

Future Trends: While facial recognition is growing, the QR code remains the most cost-effective and accessible technology for digital interaction, ensuring the term '二维码' will remain a core part of the Chinese lexicon for years to come.

你可以通过扫描这个二维码来关注我们的公众号。 (You can follow our official account by scanning this QR code.)

由于光线太暗，手机无法识别这个二维码。 (Because the light is too dim, the phone cannot recognize this QR code.)

Using 二维码 (èr wéi mǎ) correctly involves understanding the verbs and prepositions that typically accompany it. In Chinese grammar, the most common sentence structure involving this word is '扫 [Object] 的二维码' (Scan [Object]'s QR code). For example, '扫桌子上的二维码' (Scan the QR code on the table). Because the QR code is a tool for an action, it often appears in imperative sentences (commands) or as the object of a resultative verb construction.

Verb Pairing: 扫 (sǎo): The verb '扫' (to scan) is the most frequent partner. It is often doubled as '扫一扫' (sǎo yī sǎo) to sound more casual and polite, similar to 'take a quick scan.'

打开微信，点一下右上角的“扫一扫”来扫描这个二维码。 (Open WeChat and click 'Scan' in the top right corner to scan this QR code.)

Another important verb is '出示' (chū shì), which means 'to show' or 'to present.' This is used in formal situations where an authority figure or a cashier asks to see your code. For instance, '请出示您的健康码' (Please show your health code). In contrast, '打开' (dǎ kāi - to open) is used when you are the one initiating the action of bringing the code up on your screen.

Grammatical Pattern: Passive Voice: Sometimes the QR code is the subject of a passive sentence, particularly when discussing technical failures. '二维码被损坏了' (The QR code was damaged).

由于这个二维码被遮住了，扫码器无法读取。 (Because this QR code was covered, the scanner could not read it.)

In a retail context, you might hear '刷二维码' (shuā èr wéi mǎ). While '刷' (shuā) literally means 'to brush' or 'to swipe' (like a credit card), it is colloquially used for the action of scanning a QR code at a payment terminal. This reflects the linguistic transition from swiping physical cards to scanning digital codes. If you are paying for something, you might ask: '我可以刷二维码支付吗？' (Can I pay by scanning a QR code?).

请把手机靠近感应区，以便机器识别二维码。 (Please put your phone close to the sensor area so the machine can recognize the QR code.)

Compound Usage: The word is often shortened in compounds. '扫码' (sǎo mǎ - scan code) is a verb-object compound that functions as a single verb. '扫码支付' (sǎo mǎ zhī fù) means 'scan-code payment.'

现在很多餐厅都实行二维码自助点餐。 (Nowadays, many restaurants implement QR code self-service ordering.)

如果二维码模糊不清，你可以尝试手动输入号码。 (If the QR code is blurry and unclear, you can try entering the number manually.)

In China, you don't just 'hear' the word 二维码 (èr wéi mǎ); you live it. However, the auditory frequency of this word is highest in service-oriented environments. If you are at a checkout counter and the cashier is waiting for you to pay, they won't just say 'money'—they will say, '请出示您的二维码' (Please show your QR code) or '扫这个二维码' (Scan this QR code). In a busy restaurant, the waiter might point to a sticker on the corner of the table and say '扫码点餐' (Scan the code to order), without even mentioning the word 'menu' (菜单 cài dān).

Public Transportation: At subway stations, security guards or station staff might yell, '请提前打开乘车二维码' (Please open your transit QR code in advance) to keep the flow of people moving through the gates.

进站前请准备好二维码，谢谢配合。 (Please have your QR code ready before entering the station; thank you for your cooperation.)

In social settings, the word is used when making new acquaintances. Instead of asking for someone's phone number (电话号码 diàn huà hào mǎ), it is much more common to hear, '我扫你还是你扫我？' (Should I scan you, or will you scan me?). This refers to scanning each other's WeChat QR codes. The word '二维码' is implied here, but it is often explicitly used if there is any confusion about which app to use: '这是我的微信二维码' (This is my WeChat QR code).

Office and Business: During presentations or conferences, speakers will often end their talk by showing a slide with a QR code and saying, '大家可以扫码获取PPT' (Everyone can scan the code to get the PPT).

演讲结束后，屏幕上会出现一个二维码供大家下载资料。 (After the speech, a QR code will appear on the screen for everyone to download materials.)

You will also hear the word in the context of security warnings. Because QR codes can link to phishing sites, public service announcements (PSAs) often warn: '不要随意扫描陌生的二维码' (Do not scan unfamiliar QR codes at will). This highlights the dual nature of the technology—convenient but potentially risky. In banks or government offices, you might hear instructions about '身份认证二维码' (identity authentication QR code), which is used for secure logins without passwords.

为了您的账户安全，请勿将此支付二维码发给他人。 (For your account security, please do not send this payment QR code to others.)

Everyday Services: When renting a shared bike (共享单车 gòng xiǎng dān chē), the app will prompt you to '扫描车头或车锁上的二维码' (Scan the QR code on the handlebars or the lock).

如果单车上的二维码被涂改了，你就无法开锁。 (If the QR code on the bike has been defaced, you won't be able to unlock it.)

快递员把包裹放在了快递柜，并给我发了一个取件二维码。 (The courier put the package in the locker and sent me a pickup QR code.)

While 二维码 (èr wéi mǎ) is a relatively straightforward noun, learners often make mistakes regarding its collocation with verbs and its distinction from other types of 'codes.' The most frequent error is using the wrong verb for 'scanning.' English speakers might try to translate 'scan' literally using words like 浏览 (liú lǎn - to browse) or 检查 (jiǎn chá - to check), but in Chinese, only 扫 (sǎo) or 扫描 (sǎo miáo) is acceptable.

Mistake 1: Confusing 扫 (sǎo) and 刷 (shuā): Learners often think '刷' only means 'to brush teeth.' However, in the context of QR codes, '刷' is used when the code is being read by a fixed scanner (like at a subway gate). '扫' is used when you are using your phone's camera to look at a code. Using them interchangeably is common but technically imprecise.

错误：我要看一下你的二维码。 (Wrong: I want to 'look' at your QR code - implies just staring at it.)
正确：我要扫一下你的二维码。 (Correct: I want to 'scan' your QR code.)

Another common mistake is confusing 二维码 with 条形码 (tiáo xíng mǎ - barcode). A barcode is the one-dimensional series of lines found on grocery items, whereas a QR code is the square, pixelated matrix. If you call a QR code a '条形码' in a technical or retail setting, it might cause confusion, as the scanning equipment for both is often different.

Mistake 2: Incorrect Word Order with 'Show': Learners often say '显示二维码' (xiǎn shì - to display) when they mean 'show me the code.' '显示' is usually used for what a screen does. If you want a person to show you something, use '出示' (chū shì) or '给我看' (gěi wǒ kàn).

错误：屏幕出示了二维码。 (Wrong: The screen 'presented' the QR code - sounds like the screen is a person.)
正确：屏幕上显示了一个二维码。 (Correct: A QR code 'is displayed' on the screen.)

A subtle mistake involves the word '码' (mǎ) itself. In English, we use 'code' for many things: zip codes, area codes, passwords, and QR codes. In Chinese, these are all different: 邮编 (yóu biān - zip code), 区号 (qū hào - area code), 密码 (mì mǎ - password). If you simply say '码' without context, people will usually assume you mean a QR code because of its current dominance, but using '二维码' is safer to avoid being confused with '密码' (password).

不要把你的支付二维码和支付密码混淆。 (Do not confuse your payment QR code with your payment password.)

Mistake 3: Pronunciation of '维' (wéi): Some learners pronounce '维' (wéi) as 'wěi' (third tone) because they confuse it with '委' (wěi - committee). It is strictly second tone. Incorrect tones here can make '二维码' sound like 'two-tail code' (二尾码), which makes no sense.

请确保二维码完整地出现在取景框内。 (Please ensure the QR code appears completely within the viewfinder.)

如果你无法扫描，请点击“手动输入”下方的二维码。 (If you cannot scan, please click the QR code below 'Manual Entry'.)

In the digital ecosystem of China, several terms are related to 二维码 (èr wéi mǎ). Understanding these helps you navigate different technological scenarios. The most immediate relative is the 条形码, but as technology evolves, other 'codes' and 'tags' are becoming common.

二维码 vs. 条形码 (tiáo xíng mǎ): A '条形码' is a traditional 1D barcode. While QR codes (2D) are used for complex data and web links, barcodes are still primarily used for inventory and product scanning in supermarkets. QR codes are more versatile and can be scanned from any angle.

收银员先扫了商品的条形码，然后让我出示我的支付二维码。 (The cashier first scanned the product's barcode, then asked me to show my payment QR code.)

Another alternative is 验证码 (yàn zhèng mǎ - verification code). This is the 4-6 digit numeric code sent to your phone via SMS or displayed as distorted text on a website to prove you are not a robot. While it also uses the word '码,' it is a string of characters rather than a graphical matrix. Confusing these two is common for beginners because both are used for 'verification' (验证).

二维码 vs. 数字码 (shù zì mǎ): A '数字码' is simply a numeric code. In many apps, if the QR code fails to scan, you can '输入数字码' (input the numeric code) as a backup. This is frequently seen on shared bikes or package lockers.

如果二维码模糊，你可以尝试输入下方的数字码。 (If the QR code is blurry, you can try entering the numeric code below.)

In the realm of contactless tech, you might also hear about NFC (Near Field Communication) or 近场通信 (jìn chǎng tōng xìn). While not a 'code' in the visual sense, it serves the same purpose as a QR code for payments and transit. However, in China, QR codes are far more popular because they don't require specialized hardware—just a camera. Recently, 小程序码 (xiǎo chéng xù mǎ - Mini Program Code) has appeared. This is a circular, stylized version of a QR code specific to the WeChat ecosystem. While technically a 2D code, people often call it by its specific name to distinguish it from standard square QR codes.

这个圆形的二维码其实是微信的小程序码。 (This circular QR code is actually a WeChat Mini Program code.)

Comparison Table

二维码: General 2D code, used for everything.
条形码: 1D barcode, used for retail products.
验证码: SMS or image text, used for security login.
小程序码: Circular WeChat-specific code.

请扫这个二维码加入我们的会员，不要扫那个条形码。 (Please scan this QR code to join our membership; don't scan that barcode.)

虽然都是码，但二维码的信息量比条形码大得多。 (Although both are codes, the information capacity of a QR code is much larger than a barcode.)

ヒント

Be Ready to Scan

In China, always have your WeChat or Alipay ready. Scanning a QR code is often the *only* way to pay at many places.

Use '扫一扫'

When looking for the scan button in an app, look for the '扫一扫' icon. It usually looks like a square with a line through it.

Privacy Tip

Don't show your payment QR code to anyone until you are at the cashier. Scammers can sometimes 'steal' a scan from a distance.

Brightness Matters

If your code won't scan, turn up your phone's screen brightness. This is a common solution in China.

Social Scanning

When adding a new friend, it is polite to ask '我扫你还是你扫我？' to see who should open their code first.

Verb-Object

Remember that '扫码' is a verb-object phrase. You can put things in the middle, like '扫个码' (scan a code).

The 'Ma' Family

Learn '二维码', '密码', and '验证码' together. They are the 'Three Musketeers' of Chinese digital life.

Public Transit

Download the local city's transit app or use the WeChat 'Transit Code' (乘车码) to scan your way onto buses and subways.

Marketing

If you are doing business in China, your '二维码' is more important than your website URL. Put it on everything!

Mini Programs

Many QR codes don't just open a website; they open an '小程序' (mini-program). This is an app-within-an-app.

暗記しよう

記憶術

Think of 'Er' as two lines, 'Wei' as dimensions (like a web), and 'Ma' as a code. It's the 'Two-Web-Code'.

視覚的連想

Imagine a square box (the code) with two people (èr) standing inside a dimension (wéi) holding a horse (mǎ - since 'ma' sounds like horse).

Word Web

手机扫描支付微信支付宝链接信息安全

チャレンジ

Go through your day and count how many times you see a '二维码'. Every time you see one, say the word out loud.

語源

The term is a direct translation of the English technical concept. '二' (two) and '维' (dimension) combined describe the 2D nature, while '码' (code) is the standard Chinese character for codes and numbers.

元の意味： Two-dimensional code.

Sino-Tibetan (Mandarin Chinese).

文化的な背景

Be aware that for some elderly people in China, the total reliance on 二维码 can be a source of frustration or exclusion (the 'digital divide').

In English-speaking countries, QR codes were slow to catch up and were often seen as a marketing gimmick until the COVID-19 pandemic made them popular for restaurant menus.
