First of all, before we dive down into discussing the best methods of how to scan QR codes on your computer, let’s re-cap on what these codes actually are.
First designed in Japan for the automotive industry in 1994 by the Denso Wave company, the term QR is an abbreviation for “Quick Response” and the form this code comes in is basically a square bar code. As its name suggests, a QR code is meant to be “quick”. As a result of this particular code design, you can scan QR codes in a jiffy by simply hovering your smartphone camera over it.
But, what about other devices? Does QR code scanning work with every device? Is there a possibility to scan a QR code using a PC or a MAC?
How Do I Scan a QR Code on My Laptop?
Depending on your device (Android or iPhone), you should either see a preview screen and/or be navigated the desired destination.
Unfortunately, this isn’t the right solution in every single case. For instance, you may need to scan a QR code with your webcam. You might not even own a smartphone with a camera. Or, your phone may not be able to natively* scan QR codes. (* – Without downloading any extra apps)
There can be all kinds of reasons why you would not able to scan the code with your smartphone. However, there are several alternatives, the first being to print the code on paper and then try to scan it using your smartphone or your computer’s webcam.
Even more, this does sound unnecessarily complicated, which is why we got a solution to recommend – use a free QR code scanner for PC online.
How Do I Scan QR Codes Using a QR Reader?
There are tools out there that you could use to scan QR codes with your webcam. You can also use these same tools for any smartphone or tablet that do not have native QR scanning support. (Nowadays, almost all of the popular smartphone models have QR code scanning functionality implemented into them)
If this sounds good, you should know that these tools allow you to scan the code no matter where it might be. For instance, the QR code can be a part of an app or found on some website. It can also be included in a text document or an e-mail. It can even be a part of a physical product.
As long as the code is clearly visible, with nothing covering it, our free QR code scanner tool should be able to do its job. You can either scan it with your camera or upload an image. Therefore you can also take a print screen and upload that if you like.
(To get a screenshot of the QR code try the: Windows: The Snipping tool or Mac: Command+Shift+5)
Here’s what you do:
Scanning
Uploading the QR Code as an image
The best thing is that the tool will do a scan as quickly as your smartphone would. Perhaps even faster! This works for both PC and Mac computers.
Where Do I Find QR Scanners for PC and Mac?
The great thing about QR code reader for PC is that there is a lot of them out there. Some of them are paid tools and some of them are free. If the latter is your preference, you can find an excellent free QR code scanner for PC on our website that has all the premium features for free.

How to Scan a QR Code on an iPhone or Android
These days, you can find QR codes on everything from candy wrappers to billboards. Scanning these modern-day barcodes with your smartphone lets you quickly open a web page, download an app, send a text message, and much more. Many restaurants and bars are even replacing their menus with QR codes, while some stores allow you to pay with a QR code now, so you don’t have to touch anything. Here’s how to scan a QR code with your iPhone or Android phone and what to do when you can’t scan them.
How to Scan a QR Code on an iPhone
To scan a QR code on your iPhone, all you have to do is open the Camera app and point your phone at the QR code. Make sure the QR code is inside the box on your screen, and then tap the pop-up banner or the yellow QR code icon in the bottom-right corner.
If you don’t see the banner or QR icon, make sure that you have the Scan QR Codes feature enabled. You can do this by going to Settings > Camera and tapping the slider next to Scan QR Codes. You will know it is turned on when it is green.
If you still don’t see the pop-up banner or QR code icon, take a picture of the QR code and open it in the Photos app. Then tap the Live Text icon that looks like three lines in a box in the bottom-right corner. Finally, tap the QR code, and then the pop-up banner should appear.

How to Scan a QR code on an Android Phone
If you’re running Android 8 or later, you can scan a QR code by opening the camera app, pointing your phone at the QR code, and tapping the pop-up banner. If you don’t see the pop-up banner, you can use the Google Lens app to scan the QR code instead.
If you don’t see the banner appear, you can use Google Lens instead. You might see the Lens icon (which looks like a circle inside a broken box) somewhere on your screen. Or you might have to tap Modes (or More) in the bottom-right corner of the app and select Lens. Then place the QR code in the white lines and tap the magnifying glass icon to scan it.
You can also open Lens on some phones by tapping and holding the QR code on your screen until you see a multi-colored spinning wheel. Then tap the pop-up banner when it appears above the QR code.
If Google Lens isn’t working in your camera app, you might have to enable it in your settings. You can check your camera settings in the app or in the general settings on your Android. Then enable the Google Lens suggestions option.
You can also download the Google Lens app from the Google Play Store. Once you open the app, move the QR code to the center of the viewfinder and tap the magnifying glass icon at the bottom of your screen to scan it.
If you are running Android 7 or earlier, your phone might not be compatible with the app, but you might already have the Google Lens feature on your Android device. To find out, press the Home button at the bottom of your device (or the line at the bottom of your screen) until the Google Assistant pops up. Then tap the Google Lens icon or select the microphone icons and say, “open Google Lens.”
If all else fails, you can take a picture or screenshot of the QR code, open the Google Photos app, and tap the Google Lens icon below that picture.

Marketing with QR Codes
QR Codes are extremely useful for both print and digital marketing. It’s particularly useful when you use Dynamic QR Codes in your QR Code campaigns so that you can track the scan data, and update your content. To give you some inspiration for your own marketing efforts, we’ve included some fictional business examples below.
Consumer Electronics
Siekens Electronics creates high-quality electronics that users can purchase online or in-store. In order to make the setup process easier and lessen product returns, they’ve added Rating QR Codes to all their product packaging. This makes it easy for users to find the exact link and conveniently leave a review within mere seconds.
Software & Game Developers
eGo Gaming Studios recently released a new computer game. In order to spread the word and make it convenient for users to make mobile purchases, they added a Dynamic URL Code to a print magazine ad that directed users to a landing page.
Real Estate Agencies
A real estate agency like The Home Finders takes full advantage of using QR Codes to boost attendance to their property viewing events. They use Event QR Codes on property display signs and on their office window so passersby can sign up anytime.
Healthcare & Doctors
Dr. Andrew Webber wants to make sure each and every one of his patients is satisfied with his team’s dental care. They make it easy for patients to give feedback by adding a Feedback QR Code on the take-home paperwork all patients receive.
Gyms & Wellness Studios
Studio Gym is no stranger to promoting their classes with QR Codes on billboard ads. In order to compare the best locations, and determine which types of ads have the best ROI (return on investment), they use Coupon QR Codes to incentivize customers to try out their classes and then track the results.
QR Code Security: What are QR codes and are they safe to use?
QR code definition and meaning
QR stands for «Quick Response.»
While they may look simple, QR codes are capable of storing lots of data. But no matter how much they contain, when scanned, the QR code should allow the user to access information instantly – hence why it’s called a Quick Response code.
What are QR codes?
A QR code is a type of barcode that can be read easily by a digital device and which stores information as a series of pixels in a square-shaped grid. QR codes are frequently used to track information about products in a supply chain and – because many smartphones have built-in QR readers – they are often used in marketing and advertising campaigns. More recently, they have played a key role in helping to trace coronavirus exposure and slow the spread of the virus.
Check out this video on YouTube how to recognize malicious QR codes and protect yourself:
The first QR code system was invented in 1994 by the Japanese company Denso Wave, a Toyota subsidiary. They needed a more accurate way to track vehicles and parts during the manufacturing process. To achieve this, they developed a type of barcode that could encode kanji, kana, and alphanumeric characters.
Standard barcodes can only be read in one direction – top to bottom. That means they can only store a small amount of information, usually in an alphanumeric format. But a QR code is read in two directions – top to bottom and right to left. This allows it to house significantly more data.
The data stored in a QR code can include website URLs, phone numbers, or up to 4,000 characters of text. QR codes can also be used to:
The development team behind the QR code wanted to make the code easy to scan so that operatives did not waste time getting it at the right angle. They also wanted it to have a distinctive design to make it easy to identify. This led them to choose the iconic square shape that is still used today.
Denso Wave made their QR code publicly available and declared they would not exercise their patent rights. This meant anyone could make and use QR codes.
Initial uptake of the idea was slow; however, in 2002, the first mobile phones containing built-in QR readers were marketed in Japan. The use of smartphones led to an increase in the number of companies using QR codes.
In 2020, Denso Wave continued to improve on their original design. Their new QR codes include traceability, brand protection, and anti-forgery measures. There are many new uses for the QR code, from transferring payments to determining objects’ positions within augmented reality.
How do I scan QR codes?
Most smartphones have built-in QR scanners, which are sometimes built in the camera. A QR scanner is simply a way to scan QR codes.
Some tablets, such as the Apple iPad, have QR readers built into their cameras.
Some older devices may require a particular app to read QR codes – these apps are readily available on the Apple App Store and Google Play.
Scanning a QR code using your device is straightforward:
Are QR codes safe?
Attackers can embed malicious URLs containing custom malware into a QR code which could then exfiltrate data from a mobile device when scanned. It is also possible to embed a malicious URL into a QR code that directs to a phishing site, where unsuspecting users could disclose personal or financial information.
Because humans cannot read QR codes, it is easy for attackers to alter a QR code to point to an alternative resource without being detected. While many people are aware that QR codes can open a URL, they can be less aware of the other actions that QR codes can initiate on a user’s device. Aside from opening a website, these actions can include adding contacts or composing emails. This element of surprise can make QR code security threats especially problematic.
A typical attack involves placing malicious QR codes in public, sometimes covering up legitimate QR codes. Unsuspecting users who scan the code are taken to a malicious web page which could host an exploit kit, leading to device compromise or a spoofed login page to steal user credentials. Some websites do drive-by downloads, so simply visiting the site can initiate a malicious software download.
Mobile devices, in general, tend to be less secure than computers or laptops. Since QR codes are used on mobile devices, this increases the potential risks.
Do QR codes collect my personal information and data?
QR code-generating software does not collect personally identifiable information.
The data it does collect – and which is visible to the code’s creators – includes location, the number of times the code has been scanned and at what times, plus the operating system of the device which scanned the code (i.e., iPhone or Android).
Can someone hack a QR code?
The QR codes themselves can’t be hacked – the security risks associated with QR codes derive from the destination of QR codes rather than the codes themselves.
Hackers can create malicious QR codes which send users to fake websites that capture their personal data such as login credentials or even track their geolocation on their phone.
This is why mobile users should only scan codes that come from a trusted sender.
How do QR codes work?
The patterns within QR codes represent binary codes that can be interpreted to reveal the code’s data.
A QR reader can identify a standard QR code based on the three large squares outside the QR code. Once it has identified these three shapes, it knows that everything contained inside the square is a QR code.
The QR reader then analyzes the QR code by breaking the whole thing down to a grid. It looks at the individual grid squares and assigns each one a value based on whether it is black or white. It then groups grid squares to create larger patterns.
What are the parts of a QR code?
A standard QR code is identifiable based on six components:
Do QR codes collect my personal information and data?
QR code-generating software does not collect personally identifiable information.
The data it does collect – and which is visible to the code’s creators – includes location, the number of times the code has been scanned and at what times, plus the operating system of the device which scanned the code (i.e., iPhone or Android).
Types of QR code
QR codes can be used for multiple purposes, but there are four widely accepted versions of QR codes. The version used determines how data can be stored and is called the «input mode.» It can be either numeric, alphanumeric, binary, or kanji. The type of mode is communicated via the version information field in the QR code.
There are two additional modes which are modifications of the other types:
NOTE: A QR code can use multiple modes, so long as each QR code contains the correct version information field.
What are the different styles of QR code?
It is possible to create QR codes in many different shapes and styles, but five types are most commonly found. They all do the same job – they just look slightly different.
QR code use examples
QR codes are used in numerous contexts – for example:
QR codes in sales and marketing
Many advertisers use QR codes in their campaigns because it provides a faster and more intuitive way to direct people to websites than by entering URLs manually.
They can also be used to link directly to product pages online. For instance, if you were searching for the exact dress a model was wearing in a poster, a QR code could directly take you to the web page where you could purchase it.
QR codes for coronavirus tracing
The coronavirus pandemic has supercharged the use of QR codes. For example, in the UK, visitors to hospitality venues such as bars and restaurants are invited to scan a QR code upon arrival using the NHS Covid-19 tracing app. This is to help trace and stop the spread of the virus. If someone tests positive for Covid-19 at that venue, other visitors to the location are alerted by an app, thanks to the data accumulated from QR code scans.
QR codes on product packaging
You may also find QR codes on the packaging for some of your favorite products. These QR codes can reveal information about the product, such as nutritional information or special offers you can use next time you make a purchase.
QR codes in industry
QR codes were initially invented to help track parts in vehicle manufacturing, and they are still used throughout the manufacturing industry. You’ll also find QR codes used by other businesses that need to keep a close eye on products and supplies, such as the construction, engineering, and retail industries.
QR codes in postal services
Postal services around the world also use them. Because they can contain a large amount of information, they are often relied upon to track parcels. For example, global fashion brand ASOS have moved entirely to QR codes for tracking refunds.
QR codes in education
QR codes are also used in schools and colleges to help engage with students. They have appeared everywhere, from the classroom to the library, for tasks such as helping students find the books they are searching for.
How can I increase QR code security?
There’s no telling where and when you might come across a malicious QR code. That’s why it is essential to use a QR Scanner you know you can trust and not download a random one from the app store or online.
Kaspersky QR Scanner instantly checks that a scanned link is safe before submitting any information to you.
The scanner provides QR code authentication and alerts you to potential dangers behind a QR code, such as:
Kaspersky QR Scanner still provides everything you need from a QR Scanner, such as adding contacts to your phone. It also creates a log of past scans so that, if necessary, you can trace back to see when and where you may have been compromised.
