What are the different types of QR codes, and how do they work?

We can now go on to how QR codes work in people’s various spheres of interest, now that we’ve covered the fundamental notions of QR codes.

To start with, let’s explore the basic types of QR Code:

1. Static QR Code:

The information saved in a Static QR Code is irreversible. That is to say, once content has been encoded, it cannot be changed or amended. Static QR Codes always display the same content when scanned. A static code is a self-contained unit. It is unaffiliated with any service.

However, if you encode a URL in a Static QR Code, you may use UTM parameters in Google Analytics to track that URL (the only disadvantage is the URLs are pretty lengthy). In addition, a QR Code can have 7,089 characters in total. The QR Code will become denser as you add more data.

2. Dynamic QR Code:

The target data is never directly stored in a dynamic QR Code. It saves a short URL that takes users to the desired information. As a result, a dynamic QR Code can be changed at any time. There’s no need to create a new QR Code every time the encoded material changes,

Dynamic QR Codes come with a slew of extra functions. They let you follow their scanning activity, encrypt the encoded data with a password, and even capture leads, for example.

Here are ten examples of QR codes and how they work:

1. QR codes for URLs:

The most common and well-known application of QR codes is in link directories. This method allows the user to scan the QR code with a QR code scanner app from the play store/app store or their smartphone’s built-in camera. 

2. Video QR codes – for example, a YouTube video or a Google Drive video:

You can use these QR codes to email your family, friends, students, and coworkers links to videos on Youtube and Google Drive.

With this method, you may instantly replace the stress of manually typing the video’s title by scanning and viewing it without difficulty. 

3. Social Media QR Codes:

With the rise of social media dominance, QR codes have become an effective technique for gaining more followers and subscribers. Facebook, Twitter, Instagram, and Pinterest are among the social media QR codes.

4. E-mail QR codes:

These are E-mails with QR codes for business associates. The email ecosystem is prospering and thriving in 2019, with 293.6 billion emails sent and received every day.

5. Wi-Fi QR codes:

By scanning WiFi QR codes instead of writing down your WiFi password on a piece of paper, you can enjoy WiFi connectivity without the requirement for any configuration authorization. 

6. Files with QR codes:

The usefulness of QR codes for files varies depending on the user and how they use them. The simplicity of having a file QR code allows a resourceful individual to keep track of the number of files by saving and sharing them with colleagues, classmates, and affiliates who share a common interest. 

7. Mobile Applications QR codes:

QR codes for mobile apps are dynamic because they allow for data trackings such as real-time scan monitoring, device profiles, scan location, and scan date.

8. QR codes that can be used for several URLs:

QR codes with several URLs are valuable in marketing initiatives. It permits the geographical subsidiary websites of the campaign to be injected. If you are in China, you will be forwarded to the campaign’s Chinese version.

9. For the H5 editor, there are QR codes:

H5 editor QR codes are interactive QR codes that allow users to construct personalized direct web pages. H5 refers to the mobile versions of websites that are seen through mobile browsers. An H5 page is typically used to promote events and items.

10. Business Cards with QR Codes:

As the race for attractive and professional business cards heats up, QR codes for business cards may be your best weapon for staying ahead of the competition.

Because the information required on a business card can be lengthy, the space supplied by a standard business card template is insufficient.


This cannot be emphasized enough. After you’ve generated your QR Code, scan it before printing it. Because a Static QR Code can’t be changed after it’s created, make sure you test it at every step.
