Chinese use of QR codes

QR codes, an abbreviation of Quick Response codes, have existed since 1994.

Two thousand international standards were published, and QR codes became widely available.

QR codes are a method of "barcoding" a string of data. They can be used for websites, email addresses, app addresses, WeChat information, and more.

At the outset, QR codes were not widely used in Western countries. Sharing a small amount of data by voice, email, text, etc., was straightforward: "Our website is www.accesstochina.com." My email address is This email address is being protected from spambots. You need JavaScript enabled to view it., and so on.

Typically, there is a simple assumption that we all speak English and use a Latin alphabet!

That is only sometimes the case. For example;

مرحباγεια σας, 你好, Привет

In the early 2000s, China embarked on a technological revolution. As this technology became accessible to the masses, using Latin characters posed a challenge. While small Latin words used in Pinyin were manageable, long, nonsensical strings of Latin characters in a foreign language were difficult to comprehend, spell, or transcribe.

A more significant issue was passwords. Given the problem with using Latin characters, many Chinese passwords were short and only sometimes changed.

Chinese social media platforms ingeniously tackled the language barrier by employing QR codes. When scanned, these codes provide access to services through embedded, long, and complex passwords. Consequently, QR code scanning has become ubiquitous among Chinese social media users.

Since most Chinese social media users know how to scan QR codes, QR codes have become widely used in China.

Today, we see QR codes everywhere in China. They have replaced domain names in marketing and sales, and businesses and people have replaced the writing of their internet links with QR codes.

Today you see QR code everywhere in China;

• Website
• Internet login / passwords
• Supermarket
• Billboard adverts
• Information displays

QR codes have also replaced printing URLs, emails, and social media addresses on business cards.

Here are a few examples:

A QR code can be in different colours and styles, with or without logos embedded in the centre.

The significant advantage of QR codes over barcodes is that they are flexible and can store different types and volumes of data.

Given that people no longer have to type the URL, you can add additional information to the URL to track the inquiry source, e.g., use different URLs on brochures, websites, promotions, etc. You can also track the use of your QR codes.

At this point in China, you are seeing QR throughout China and increasing use worldwide.

Are there a few problems;

• Outside China, not everyone uses, knows, or has a QR scan on their Mobile Phone. Your URL must still be printed on brochures, business cards, etc.
• The longer the URL, passwords, etc., the more complex the QR code. This can make it too large to be read successfully.
• The QR code colour must contrast with the background colour. A QR code is successfully scanned if there is a sharp contrast between the background and the QR code colour. For example, the image of the Access to China home page ( https://www.accesstochina.com ) has a black QR code in the top right-hand corner. It is not our regular QR code; see above; the change was necessary to allow it to be read successfully.
• When creating a QR code, add http;// or https:// to the front of the website, e.g., http://www.accesstochina.com, or for email, mailto:This email address is being protected from spambots. You need JavaScript enabled to view it..
• You must test your QR code before publishing. Many problems with QR codes are corrected at the outset with a few simple tests.

Access to China QR code recommendations

• Create QR codes and publish them on all marketing materials, business cards, etc.
• Add your QR code(s) to your company website's home page. In China, readers/users often transfer web content from desktops to mobiles; a QR code makes this straightforward.
• Use different URL codes to track business sources such as Brochures, Business cards, and websites.
• Always check and test that QR codes are working both for seeing the website and tracking system.
• Do not use a lengthy URL or email address, as the QR code becomes too complex and challenging for QR scanners to read.

We recommend using the free QR code generators to understand how they work and what design characteristics look right for your business. QR code design companies are available on the internet if you need assistance.

If you are looking to create a QR code, you can find many free tools on the internet to generate it, e.g., https://www.unitag.io/qrcode
