QR codes are small, convenient 2D symbols that can store information in a unique way. At first glance, they might look like random patterns, but to a QR code scanner, they convey clear and structured data.
When you scan a QR code, it can redirect you to a webpage, open a dialog box, or even display text in an app on your device.
QR codes have many applications, but from a marketing perspective, they are particularly valuable because they add interactivity and accessibility. This is why you see them everywhere—on online stores, blogs, social media, and even academic journals.
However, with so many uses, it’s important to test QR codes to ensure they work correctly. If you’re in marketing and planning to use QR codes, here are some essential test cases to check before launching your QR campaign.
What are Static And Dynamic QR Codes
Before getting started, it’s important to understand the different types of QR codes, since you’ll be using them in your marketing campaign.
Static QR Codes
Static QR codes are codes whose content cannot be changed once they are created or printed. No matter what type of data—URL, text, or file—is stored in the code, it will always display the same information when scanned.
In other words, once a static QR code is printed or distributed, the content is permanent and cannot be updated.
Static QR codes are perfect for situations where the information does not need to change, such as business contact details, product packaging, or event info. You’ll see many practical use cases for static QR codes later in this guide.
Dynamic QR Codes
Dynamic QR codes are QR codes whose content can be changed even after printing or distribution. For example, a QR code initially linking to a webpage can later be updated to display a text file, video, or any other type of content.
This flexibility is possible because a dynamic QR code points to an online database. When someone scans the code, the content from the database is displayed. By updating the database, you can change what users see without reprinting the QR code.
Dynamic QR codes also offer valuable tracking and analytics. You can monitor how many times the code was scanned, the location of the scans, the device used, and more. This makes dynamic QR codes a powerful tool for marketing insights and campaign optimization.
As you might expect, dynamic QR codes are more popular and versatile than static QR codes. However, static QR codes are much easier to create. You can easily find a free QR code generator online and generate one within minutes.
That is not the case with dynamic QR codes.
Sample QR Codes for Testing
Now that we’ve covered the basic types of QR codes, it’s time to look at which types of QR codes should be tested before using them in your campaign.
1. URL QR Code
The most common type of QR code is one that stores a URL. This could link to a blog, online store, social media page, landing page, or any other webpage. Depending on your needs, you can choose either a static or dynamic QR code for this purpose.
- Static QR code: Best if the URL is unlikely to change, such as a long-term landing page or permanent website.
- Dynamic QR code: Ideal if you plan to update the link later or want to track scans and engagement.
Some QR code generators let you customize the design, such as adding a logo in the center of the code. If you’re using QR codes for branding purposes, these customization options can help make your codes more recognizable and visually appealing.
2. VCard QR Code
A VCard QR code stores and shares contact information. When scanned, it automatically provides details like name, phone number, email, and other contact info, making it easy to save someone’s details without manual entry.
Since contact information usually stays the same over time, static QR codes are ideal for VCards.
On a mobile device, scanning a VCard QR code will trigger a pop-up on your screen. From there, you can save the contact information, make a call, send an email, or even send an SMS directly making it quick and convenient to connect.
3. Email QR Code
An Email QR code automatically opens your device’s email app when scanned and generates a template email to a specific address. If your device doesn’t have an email app, the content will appear in a notepad app instead.
When creating this QR code, you can pre-fill the email address, subject line, content, and signature for convenience.
For simple template emails, a static QR code works perfectly.
You could use a dynamic QR code for this, but in most cases, it’s not necessary. A static QR code is usually sufficient.
4. SMS QR Code
SMS QR codes work similarly to Email QR codes. Instead of an email address, you enter a phone number, and the subject line is removed. You can also pre-write a custom message that will appear when the code is scanned.
Once created, scanning the QR code generates a template SMS ready to send to the specified number. This is particularly useful for surveys, feedback forms, or quick responses. Businesses often place SMS QR codes on brochures, menus, pamphlets, or other marketing materials to encourage engagement.
On most smartphones, scanning an SMS QR code will automatically open the default SMS app. The recipient’s number and pre-written message will be filled in automatically, making it quick and easy for the user to send.
5. WiFi QR Code
A WiFi QR code is designed to share WiFi login credentials securely. Since WiFi networks are password-protected, you usually need to be careful about sharing access.
Manually giving someone your password—or typing it into their device—can feel inconvenient or even awkward. It might come across as distrustful if not handled carefully.
A WiFi QR code solves this problem. Simply provide the QR code, and anyone can connect to your WiFi instantly without ever seeing the password. It’s secure, fast, and convenient.
6. Social Media Share QR Code
A Social Media Share QR code allows users to copy a webpage link and share it as a post on their preferred social media platform.
This type of QR code is a smart way to increase the reach of your content. You can also include a call-to-action (CTA) on the webpage encouraging visitors to share it via the QR code, further boosting engagement and visibility.
7. File QR Code
A File QR code allows users to download or open a file (like a TXT document) directly on their device when scanned. This makes it convenient for sharing documents, instructions, or any digital files that need to be easily accessible.
One of the biggest advantages of a File QR code is that it reduces paper usage. You can simply print the QR code and place it in a public area—anyone who needs the document can scan it to access the file instantly.
8. Phone Number QR Code
A Phone Number QR code is a simplified version of a VCard QR code. Unlike a full VCard, it only contains a name and phone number.
When scanned, this QR code automatically opens your contacts app with the information pre-filled, making it easy to save the contact without typing anything manually.
9. Location QR Code
A Location QR code stores latitude and longitude coordinates. When scanned, it automatically opens your device’s maps app and shows the exact location.
One practical use is on hiking trails or areas with poor network or GPS reception. QR codes placed at intervals along the trail can help users pinpoint their location on a map without needing a network or GPS signal.
You can scan this sample Location QR code to see a random coordinate we used for demonstration purposes.
10. Event QR Code
Event QR codes are perfect for occasions like birthday parties, weddings, award ceremonies, and other gatherings. Instead of sending individual invitations, you can create a QR code and share it in a group chat or via email for all attendees.
When scanned, the Event QR code displays a popup with essential details, including:
- Event name
- Venue address
- Date
- Time
This makes it a quick and convenient way to provide event information to guests.
Why Test QR Codes?
Testing QR codes is essential because errors can cause inconvenience and reduce engagement. Here are the main reasons why QR code testing is important:
1. Testing Links
For URL and Social Media Share QR codes, it’s important to check that the links work correctly. A faulty QR code might lead to the wrong page, an incomplete link, or a dead link.
By testing QR codes in advance, you can catch and fix these issues before they cause problems for your audience.
2. Testing on Different Platforms and Operating Systems
QR codes may behave differently depending on the device, operating system, or platform.
A QR code may scan easily on an Android device but cause security warnings or errors on iOS.
Similarly, scanners on Windows, Linux, or web browsers may not always recognize the code properly.
Comprehensive testing across devices ensures your QR code works smoothly everywhere.
3. Location Testing
Location testing involves scanning the same QR code from different geographical regions.
Different locations can have varying network quality or ISP restrictions, which may affect whether a QR code works properly. Some regions may scan the code without issue, while others may face errors.
Testing QR codes in multiple locations helps you identify and resolve location-specific problems.
4. Screen and Color Testing
QR codes can include custom colors, shapes, or logos for branding purposes. However, different screens display colors and contrast differently:
- A QR code may look perfect on an OLED/AMOLED display but appear dull on IPS, VA, or TN panels.
- A QR code might scan well on a large desktop monitor but have issues on a smaller smartphone screen.
Testing across various screen types and sizes ensures your QR codes look good and function properly everywhere.
This kind of thorough testing guarantees that your QR codes are reliable, visually appealing, and functional for all users.
