QR codes have been around a while now, and they don’t seem to be going away any time soon. That’s a good thing because they can benefit your WordPress site for sales, awareness, engagement, and more.
Though they look complicated, adding a WordPress QR code is simple to do — and free!
Are they that great? Well, considering mobile QR code coupon redemptions are expected to surge and surpass 5.3 billion by 2022 — it’s a better time than ever to use QR codes to your advantage.
In this article, we’re going to take a look at:
There are a lot of ways to implement them with plugins and other resources, such as QR Code Google Chrome Extension (which we’ll be going over).
After reading, you’ll understand how QR codes can add additional value to your WordPress site and your users.
You’re more than likely familiar with them. They’re the funny-looking square objects you see on items, videos, ads — just about anything.
QR, or Quick Response codes, are similar to the barcodes you see on many products’ packaging. The main difference between the two is that QR codes can hold a lot more data than traditional barcodes.
QR codes can store up to 7089 digits or 4296 characters. That includes punctuation marks and special characters.
It can equally encode words and phrases (e.g. URLs). The more data added to a QR code, the more the size increases, and its structure becomes more complex.
When scanned by a compatible device, including a camera-equipped smartphone, that data is extracted.
What’s nice is that even if it’s damaged, a QR code’s structure data keys include duplications, so it allows up to 30% of the code structure to be damaged without affecting its ability to be scanned. (e.g. coupons, interactive links, etc.)
QR codes use is relatively straightforward. They can be used on your website for numerous purposes; everything from coupons to contact information.
There are two types of QR codes: Static and Dynamic.
A Static QR code is fixed, and you’re not able to edit once the code has been generated. It’s the best code to use for personal use (e.g. access to home WiFi by scanning the QR code).
Dynamic QR code can be edited, updated, and changed however times you need. It’s ideal for ad campaigns, sales, coupons, and more (e.g. share your social media platform on a print ad).
QR codes are essentially a shortcut to information in this mobile world. Some of the most common uses for QR codes include:
- Social Media
For a good example of how they’re used on a bigger scale and how relevant they are, a recent CNN article mentions that QR codes are potentially going to be used with COVID-19 passports as a means of knowing who is vaccinated.
With all of that being said, let’s take a look at…
As you’ll see, there are many ways you can use QR codes on WordPress.
In print media, they are often used to make it easier to visit a website by encoding a URL in the code. When scanned, the code will open the website on a phone’s browser, saving the user the trouble of typing in the address. However, if your visitors are already viewing your website, this isn’t a helpful way to use them!
While it might be tempting to start using QR codes all over your website due to their novelty factor, less is more. It’s best to use them wisely to ensure they benefit your visitors rather than become a distraction.
So let’s take a look at some example uses for QR codes.
As well as the standard email contact form, you can provide an easy way for your visitors to get in touch with you to add a QR code to your contact page.
Depending on how you create a QR code, your users can either send you an email on their phone or send you an SMS message once scanned.
Suppose you prefer not to receive inquiries about your services via email. In that case, this can be a great way to encourage your potential clients and customers to contact you via SMS while also saving them the effort of manually entering your contact details.
File Download Links
Another way to use a QR code on your site is to link it to a file that your users can download. This could be an audio file for a podcast, a PDF containing an eBook, or any other content that is well-suited to be consumed on the move on a mobile device.
Want customers to stop by? Adding a QR code to your contact page, which links to an online map that is locked into your location, is a great way to simplify visitors’ process of looking up your location on their phone. This can then be used for navigational purposes when they are making their way to your premises.
Another widespread use for QR cards that translates well to online publishing is sharing contact details using the vCard format.
This gives your visitors an easy way to store your details in their phone as one of their contacts, rather than entering them manually.
Suppose you are offering your visitors a mobile app or linking out to apps created by others. In that case, you can create a QR code that links to the app and automatically redirects visitors to the correct store based on the device they are using.
Add a “Clickable” Link to Printed Pages
If your visitors are printing pages from your website, you can make it easier for them to find their way back to your online content later on by inserting a QR code into the footer of printed copies of your pages.
Last but not least is perhaps the most practical use for QR codes on a WordPress site: adding two-step verification to the login process.
Our own security plugin, Defender, has a 2FA feature that uses a QR code in collaboration with Google Authenticator.
To take things to the next level, you can set your website to require that a trusted device scans the QR code on the login page.
This helps ensure that even if your passwords get compromised, unless a hacker also has access to your mobile device, they won’t be able to log into your site.
If this sounds like an appealing way of increasing your WordPress website’s security, Rublon is a free plugin that adds QR code-based two-factor authentication to a WordPress site.
For an alternative, you can explore these six security authentication plugins for WordPress.
Along with Rubion, there are some other great QR code plugins to consider for your WordPress. They all function differently and offer specific features.
We’ll take a look at several free QR plugins to check out. The market on WP.org of QR plugins is relatively small; however, there are some decent choices. All of these are free and up-to-date.
The Kaya QR Code Generator makes it quick and easy to add a QR code to your WordPress site. It’s all done via a widget or shortcode.

However, it has an Error Correctional Level that can be adjusted. It will automatically update all of the shortcodes on your WordPress site when adjusting the size or Error Correctional Level.
QR Code MeCard/vCard Generator
The QR Code MeCard/vCard Generator was made for sharing contact information with a QR code embedded on your WordPress site.
