Overview
二维码（QR Code，Quick Response Code的缩写）是一种二维条形码，由日本Denso Wave公司于1994年发明。与传统的条形码只能在一维方向（水平）上存储信息不同，二维码可以在水平和垂直两个方向上存储信息，因此其信息容量远大于传统条形码。它由黑白色的像素点阵列组成，可以通过智能手机或专用扫描设备快速读取和解码。
二维码的应用非常广泛，主要体现在以下几个方面：
社交与分享：方便地分享个人名片、社交媒体账号、活动信息等。
二维码在日常生活中随处可见，尤其是在以下场景：
- 商业广告：产品包装、海报、传单上印有二维码，引导消费者访问官网、查看详情或参与促销活动。
- 移动支付：支付宝、微信支付等App中，生成付款码或扫描商家收款码进行支付。
- 交通出行：火车票、飞机票、景点门票上印有二维码，用于检票或身份识别。
- 餐饮服务：餐厅菜单、点餐系统中使用二维码，方便顾客扫码浏览菜单或下单。
- 社交媒体：微信、QQ等社交平台中，用于添加好友、分享个人信息或加入群组。
- 公共信息：公交站牌、信息亭上可能印有二维码，提供更详细的路线信息或服务指南。
与“条形码”（Barcode）相比，二维码在信息容量、纠错能力和读取方式上都有显著优势。条形码通常只能存储少量数字或字母信息，且需要特定的扫描设备，而二维码可以存储大量多类型数据，且大多数智能手机摄像头都能轻松识别。在外观上，条形码是一维的直线状，而二维码是二维的方块状点阵。在功能上，二维码的应用场景更丰富，尤其是在互联网和移动支付领域。

How to Use It
Notas de uso
QR codes are extremely common in daily life, particularly for mobile interactions. They are used across informal, neutral, and formal contexts, from casual sharing to official ticketing and payments. The term is universally understood in contexts involving smartphones and digital information.
Errores comunes
Users might mistakenly believe QR codes are inherently secure; they are merely a data encoding method. The security depends on the destination linked by the code. Also, confusing them with traditional barcodes can lead to misunderstandings about their capabilities.
Tips
Scan with Caution
Always be mindful of where a QR code leads before scanning. Avoid scanning codes from untrusted sources to prevent potential security risks.
Check Link Destination
Some QR codes might redirect to phishing websites or download malware. Verify the URL or action before proceeding after scanning.
Ubiquitous in Asia
QR codes are extremely prevalent in East Asian countries like China for payments, information access, and more, integrated deeply into daily life.
Origen de la palabra
The term 'QR Code' is a trademarked name derived from 'Quick Response Code', emphasizing its intended speed of use. It was developed by Denso Wave, a subsidiary of Toyota.
Contexto cultural
In many East Asian cultures, particularly China, QR codes are deeply integrated into daily life, functioning as the primary method for mobile payments, accessing menus, sharing contact information, and even for official communication.
Truco para recordar
Imagine a 'Q' for 'Quick' and 'R' for 'Response', linked to a square grid ('code') that holds information you can access rapidly.
Preguntas frecuentes
4 preguntas二维码（QR Code）是二维的，信息容量远大于一维的条形码。二维码可以存储文字、网址等多种信息，而条形码通常只能存储数字或字母。此外，二维码具有更强的纠错能力。
通常只需要一部带有摄像头的智能手机，并安装相应的扫描App（如微信、支付宝或专门的二维码扫描器）。一些专用扫描设备也可以读取二维码。
二维码能存储的信息量取决于其规格和容错级别，理论上可以存储数千个字母数字字符，或更多的二进制数据。常见的应用场景如网址、联系人信息等通常只占其中一小部分容量。
二维码本身是一种编码技术，不具备安全性。扫描二维码时，如果链接指向恶意网站或包含病毒，则可能存在风险。因此，应谨慎扫描来源不明的二维码，并确保手机安装了安全防护软件。
