What are QR Codes?

QR（快速响应）代码是一种特殊类型的条形码，允许用户在其移动设备和应用程序上使用扫描仪访问或提供信息；无触摸和快速。他们为用户提供即时信息，或者将用户引导采取一些立即行动。例如，零售商可能会将QR码放在公交车站的广告上。当有人扫描QR码时，他们的手机将立即打开选定的网页。一家英国公司，QE的回忆甚至创建了QR码来登上墓碑，人们可以扫描以了解有关死者的生活的更多信息。

顾名思义，QR码允许用户快速访问和提供信息。他们可以在方形的网格中存储多达7089个数字或4296个字符。

QR码设计的一个有用功能是，它在其数据键中包含重复，这意味着人们即使造成30％的损坏也可以成功扫描QR码。

One of the reasons that many countries have chosen to incorporate QR codes into their Covid scanning is that they can easily create distinct QR codes for every business/venue. When somebody scans a QR code in their Covid app, it records that they have been to that place at a specific date and time. All this happens relatively quickly, making it practical for businesses and other venues with reasonably large numbers going through.

Why Are QR Codes Gaining Popularity?

Toyota子公司Denso Wave于1994年发明了QR码，作为在制造过程中扫描汽车组件的快速方法。作为日本人，他们必须找到一个可以处理英语字母的系统。结果，他们开发了一种特殊的条形码，可以编码汉字，卡纳和字母数字字符。

Unlike traditional barcodes, you can read QR codes from top to bottom and right to left. This means that QR codes can hold much more information than standard barcodes, up to 4,000 characters of text. The developers deliberately designed the code to be easy to scan from any angle, which is why it's square. They also wanted to ensure that their workforce could easily distinguish QR codes from any other barcodes.

It took a while for QR code usage to become commonplace, however. The first phones with QR code readers were marketed in Japan in 2002, which sparked more companies to use QR codes.

Their usage has widened considerably in recent years, however. This is partly because of an explosion in mobile phone usage. There are now 5.29 billion mobile phone users globally, 67.1% of the world's population. This figure grew by 1.9% in the year to October 2021. Most of the world has converted to smartphones. For example, 89.6% of all internet users use smartphones to gain access, compared to just 4.8% of old-style feature phones. The average speed of mobile internet connections has also improved to now be 56.74 MBPS. As a result, more of the world's population now has access to usable technology, and QR codes are a simple, straightforward way to transact and deliver information.

QR codes have now become widespread in many parts of the world, which has encouraged more businesses to find ways to use the technology. As a result, different types of companies have experimented with using QR codes over time, and others in their industries have followed suit, increasing their usage further.

Denso Wave, the original QR code inventors, added additional capabilities to QR codes in 2020, including traceability, brand protection, and anti-forgery measures.

您如何扫描QR码？

大多数智能手机和平板电脑都将内置QR扫描仪作为相机的一部分。但是，如果您的手机没有用于扫描QR码的内置应用程序，则您会在Android和iOS应用商店中找到许多。

要读取QR码，您所要做的就是将手机的相机指向QR码。通常，您的角度无关紧要。但是，根据手机的不同，您可能首先需要首先打开特定的应用程序。

Your phone will read data from the QR code and then do what the QR code asks. For example, it may bring up a particular type of information, take you to a specific webpage, record your presence for contact tracing, or start a payment process.

Parts of a QR Code

There are seven parts to a QR code:

1. 安静区域 - 代码周围空的白色边框。这对于扫描仪识别QR码是必要的。
2. Finder pattern, aka positioning detection markers, are the three black squares in the bottom left, top left, and top right corners. These are used to orientate a scanner and indicate where the code's boundaries are.
3. 对齐方式 - 右下角附近的较小正方形，有助于扫描仪方向和阅读。它有助于拉直QR码在弯曲的表面上。
4. Timing pattern – an L-shaped dotted line that connects the inner corners of the three large squares. It helps the scanner identify individual squares within the code and determine how large the data matrix is.
5. 版本信息 - 右上角附近的一小部分信息字段，识别正在读取的QR码的版本。目前有40多个版本，尽管最常见的是版本1至7。
6. Data cells – the rest of the QR code encodes the actual information being conveyed. In addition, it includes some format information and error correction keys.
7. 格式信息 - 其中包含有关误差容量和数据掩码模式的信息，并使扫描QR码更容易。

Static vs. Dynamic QR Codes

There are two distinct types of QR codes:

1. Static QR codes – contains information that is fixed and uneditable. Typical Static QR code uses are:
   1. WiFi – use this to help friends and family connect to your WiFi network
   2. 比特币 - 将比特币和其他加密货币变成QR码，以平滑加密货币交易
   3. 纯文本 - 显示最多300个字符的消息
   4. VCARD - 分享您的业务联系方式的一种方式，也许在您的名片上
   5. 电子邮件 - 为客户提供可以用来与您联系的客户提供的电子邮件
2. 动态QR码——你可以更新、编辑和改变the type of the QR Code as many times as you need. When people scan a dynamic QR code, they are actually scanning a short redirection URL, meaning you don't have to store all the data in the code. You can use dynamic QR codes to capture information. Typical Dynamic QR uses are:
   1. App Store – links to multiple app stores with one scan
   2. PDF – downloads digital magazines, brochures, eBooks, etc.
   3. Social media – use a QR code to share your social platforms
   4. Coupon – customers can scan a coupon to their smartphones and share it on social media and email. They can even redeem it at a nearby location or online store
   5. Business page – can provide details about your business with the QR code, even if you don't have a website.

您可以在我们的免费QR码生成器工具中制作许多静态和动态代码。

QR码的使用

QR codes may have been invented to help with inventory control, but they now have many other uses. These include:

1. Industry

QR codes began in industry, and firms still use them regularly there. They are frequently used to track parts, products, and supplies.

2.数字付款

一些付款应用程序将QR码包含在人们付款的快速简便方法中。在结帐时，用户只需在手机上扫描QR码即可。这会自动启动付款屏幕。用户确认付款（假设附件有可用的钱），完成交易仅需几秒钟即可。

3.购物

Brands are finding multiple ways to use QR codes to assist with different stages of the purchasing process.

一些公司提供QR码，然后客户扫描订单。

其他公司使用QR码向其客户提供其他信息。例如，消费者可以在包装上扫描QR码，以获取有关产品的可持续性和能源所使用的信息。

Best Buy，Home Depot和Staples之类的公司在其实体店中添加了QR码。结果，客户可以快速获取有关产品的信息，而不是通过竞争对手的在线网站获得有关产品的信息。QR码可立即访问视频，产品和操作内容，然后客户可以在店内购买或使用其应用程序。此外，QR码可能会提供机会在客户正在浏览的特定商店中购买库存的多种库存。

4.餐馆

QR码在许多餐馆中变得司空见惯。吐司describes the typical process used:

1. 餐馆坐在桌子上，并在菜单上扫描QR码
2. Often, they can then pick items from the menu using a QR code and send the order directly from their phone to the kitchen
3. 一旦饭菜完成，收据可能包括唯一的QR码。食客可以使用智能手机立即从桌子上付款

5.邮政服务

Many postal services now keep track of mail through the use of QR codes.

6.营销

如今，QR代码最常见的用途之一是用于营销。公司定期将QR码添加到各种媒体的广告中，从杂志展示广告到广告牌。您可以使用QR码作为传达其他信息的快速简单方法。您甚至可以链接到优惠券和折扣页。

You can use QR codes to drive people to your website. You do this by including them in another form of marketing. For example, you might insert your QR code in a magazine ad. Anyone who scans your QR code will go directly to a customized landing page on your website. It's much easier than requiring them to type in a URL, particularly in traditional media where clickable links don't work. Similarly, you can use a QR code to promote your app, taking people directly to your section of the app store.

一些公司使用QR码帮助人们找到业务。当有人扫描QR码时，它会打开Goog​​le地图以显示其物理地址。这也是放置在名片上的QR码的另一种用途。

7. Product Reviews and Ratings

You can use QR codes to encourage customer reviews and ratings of your products and customer service. Consider including a QR code on your business card, email signature, or website asking for feedback. You can use special QR codes to assist with this, making it easy for customers. Rating QR codes collect a rating from people on a ten-point scale. They simply scan the code and give their rating, which is then sent to your email address.

Alternatively, you can include a Feedback QR code to collect information via a Google Form. When somebody scans your QR code, they are sent directly to your questionnaire.

8. Contact Tracing

As we referred to at the start of this article, many countries have chosen QR codes as an integral part of their Covid tracing. For example, in New Zealand, the Ministry of Health created theNZ Covid Tracer app。这取决于扫描QR码和蓝牙跟踪的组合。

夏娃ry retailer and many other types of businesses and locations have individualized QR codes. There are even different QR codes for separate train and bus trips. When somebody visits a place with a QR sign, they scan before entering. The app records where they were at that particular time. If they later find they have COVID, they can share their digital diary with contact tracers. In addition, their Bluetooth Tracing keys can find other app users who have been close to the person with Covid.

The NZ app, at least, incorporates privacy precautions, with your digital diary being stored securely on your phone and deleted automatically after 60 days and Bluetooth data automatically deleted after 14 days.

QR码安全性

像几乎所有类型的现代技术一样，使用QR码时，您必须保持警惕。根据安全公司的报道Kaspersky, a determined attacker could embed malicious URLs containing custom malware into a QR code. It could then take data from a mobile device when scanned or even embed a malicious URL into a QR code that directs to a phishing site.

但是，QR码本身不能被黑客入侵。而且，QR代码生成软件不会收集个人身份信息（请注意，任何共谋理论家。）收集的数据与位置扫描有关，在什么时间和操作系统上扫描了代码的次数扫描代码的设备。

卡巴斯基建议移动用户只能扫描来自受信任发送者的代码。
