Quest for the Hidden QR Code: How to Hide a QR Code?

A hidden QR code or a camouflaged QR code on an image makes it difficult for users to spot them at first glance, giving it an illusion of being hidden.

Placing it like it’s a  hidden QR code on print materials or digital templates is an innovative way to engage with audiences and keep them on their toes.

Hiding QR codes in print materials or online ads will increase users’ interest, leaving a good impression of your material.

This way, your audience will interact more with your brand since they’ll be interested in finding your QR code and discovering what data lies behind it.

If you want to get ideas for this, you’ve come to the right place.

Check out how you can create a QR code using the best QR code generator and hide it flawlessly.

Ways to hide a QR code

There are several methods that you can use to hide a QR code. Check out the examples below for your reference.

Hide the QR code in the image

Hidden QR code

You can disguise your QR code as part of an image.

Since visual QR codes are customizable, you can add them to the overall picture using the same color scheme.

By doing so, you will still be able to maintain the image’s aesthetic, and users won’t notice that you hide a QR code in that image.

This method is applicable for marketers hosting a scavenger hunt for promo codes.

They can hide the QR code on product packaging and see the lucky consumers who will notice that hidden code to win amazing surprises.


Blend QR codes in artwork

As an artist, sharing your artwork and its details are both important.

Some artists have already used QR codes on their masterpieces for transparency, such as materials used, inspiration, and details about the artists.

But did you know that you can blend QR codes right into your actual artwork?

In the study “Aesthetic QR Codes Based on Two-Stage Image Blending” by Zhang et al., they blended module-based and pixel-based blending and maintained the correction-error level.

Invisible QR code thru nanotechnology

Invisible QR code

Counterfeit money poses a potential threat as it can reduce real currencies’ value and lead to inflation.

This is why installing QR codes for added security is a must.

To combat this staggering problem, US researchers created a hidden QR code on banknotes.

They used nanoparticles to develop this tiny detail. 

The QR codes created can be seen under an infrared laser light but are still scannable using smartphones.

They combined blue and green fluorescence ink so users could only see them under infrared light.

This method may not be achievable yet for most.

But if you have the same resources, you can try this technique to create an invisible QR code.

Print on a hidden area

There’s no better way to hide a QR code than actually hiding the QR code. Do not just change its colors so it’ll blend with the surroundings.

Hide it somewhere no one will see.

This technique is great for scavenger hunts and games, especially for companies promoting their product.

You can print it behind a product’s label, so only those who peel off the packaging can scan the QR code.

The finding-QR code gimmick could form part of the overall promotional stint.

How to make a QR code using the best QR code generator

Marvel has always been fond of discreetly placing the QR codes in many of its series, waiting for the audience to spot them.

In Marvel’s Moon Knight, they make the QR code appear less visible and less noticeable in the season’s first, second, and fifth episodes.

Each redirects to a free digital copy of the Moon Knight comics.

Even in the first episode of Ms. Marvel,  viewers found a QR code displayed on an ATM during a scene between characters Kamala Khan and Bruno in a store.

The code redirects to a Ms. Marvel 2014 webcomic.

A QR code on the wall in one of She Hulk’s episodes also leads to a website where audiences can access the 1980s The Savage She-Hulk #1 comic. 

QR codes hiding in video games

Portal RTX, the updated version of the game Portal, introduced secret QR codes across their game world.

Scanning one will reveal a secret code that will open up a new cube and change the game display.

Another unnoticeable QR code is on one of the scenes in the video game High On Life.

You can see the character Tweeg eating from a cereal box with a QR code.

When scanned, it will lead scanners to the Squanch game site, where they can play more games.

Music videos with QR codes

There’s a QR code hiding in plain sight in Charlie Puth and BTS Jungkook’s Left and Right music video.

Most people thought of it only as a prop, while others dismissed it as they focused more on the song and the artists.

But here’s the surprise: The QR code works. When scanned, it redirects to Puth’s official website, where fans can order the limited-edition CD single of the song.
