Scan QR Code On Laptop Screens In 7 Easy Steps

Did you know that you can scan QR code on laptop screen? That’s right—QR codes are not only scannable when printed. 

You can still scan a QR code even when it’s shared digitally. As long as the significant points of the code are clear, a scanner can decode it.

Check out how you can do so and how to create a unique QR code using a free QR code generator from this blog.

The basics of QR codes: Static vs. dynamic

Before diving into the scanning part, let’s first get to know what is a dynamic QR code and how they differ with static ones?

QR codes evolved from bar codes. These codes were first created to aid in the logistics industry in Japan.

Today, QR codes are more flexible and are being used in many different industries like retail, marketing, and food and beverage industries. A free QR code generator offers this in two forms: static and dynamic.

Static QR code

These types of codes are permanent and best for non-updatable content. If you want to embed permanent data that does not require constant editing, then static codes are the best choice.

Plus, static QR codes are also free. You don’t have to pay a penny when using this solution. However, its features are limited compared to dynamic QR codes.

Dynamic QR code

Dynamic QR codes, however, are perfect for complex campaigns like marketing and advertisement that must be updated each time.

Although not a free code—it requires a subscription for continuous use and comes with several features helpful in creating better campaigns like edit, track, password-protect, and expiry.

What is a QR code scanner?

Scan QR code

A QR code scanner for PC or mobile is any device or software application designed to decode QR codes.

Without a QR code scanner, you won’t be able to interpret the embedded data in a QR code.

QR code scanners play a significant role in modern technology, offering a quick and convenient way to access information or perform actions simply by scanning a code with a compatible device or application.

How to scan QR code on laptop?

Do you have a QR code flashed on your laptop screen or saved in your laptop gallery? Here’s how you can scan your code in three easy ways:

Using your smartphone’s camera

If you’re using an Android 8 and up version or an iOS 11 and later version, then using your camera as a scanner should work.

1. Flash the QR code on your laptop screen.

2. Open your phone camera and position over the QR code.

3. Wait for the scanning to begin.

Using a third-party scanner

If your phone’s camera is not working after doing the steps above, you might need to use an application to scan a web QR code.

1. Download any third-party scanner from your app store. Make sure to pick one with a good review.

2. Launch the application to open up the scanner.

3. Position over the QR code and wait for the scanning to begin.

Using the Google Lens as Web QR code scanner

1. Open the Google app on your Android device. Tap the Google Lens icon (usually located in the search bar) or access it through the camera by holding down the home button and selecting Google Lens.

2. Aim your phone’s camera at the QR code you want to scan. Make sure the code is within the camera’s viewfinder. 

3. Google Lens will automatically recognize the QR code and display relevant options or information based on the content of the code.

What hinders a successful QR code scanning for PC and mobile?

Sometimes, no matter how great you are at following instructions on how to scan a code, scanning errors might still happen. That’s why it’s important to have a QR code test first distribution.

If so, check out the following reasons that might have been causing these errors:

Low-quality codes

QR codes must be printed or displayed in high quality for scanners to interpret them accurately. Low-resolution or distorted codes might not scan properly.

One reason for having a low-quality QR code is using the wrong type of QR code. Go for dynamic QR code solutions if you’re about to embed a huge amount of data.

Using static QR codes for huge files, whose data is directly embedded in the pattern itself, will damage the pattern. And a damaged pattern will create scanning errors in return.

Damage or distortion

Although QR codes have an error-correction feature, too much physical damage like scratches, smudges, or partial covering of QR codes can hinder scanning.

Distortion due to stretching, bending, or uneven surfaces can also impact readability. Check for these factors when you scan QR code on laptop, especially dents that might be causing these scanning errors.

Poor lighting conditions

Properly lighted laptop QR code

Another tip on how to scan qr code from picture on laptop successfully is through enough lighting.

Insufficient lighting or strong glare can interfere with a scanner’s ability to recognize and decode QR codes accurately.

When scanning a QR code, make sure to have sufficient light in the area or turn or your device’s flash to give enough light.

Encoding errors

Scanning errors usually begin with the code generation itself. If you generate a problematic QR code in the first place, then it will really create scanning problems afterward.

Generally, mistakes in generating the QR code or errors in the encoded information can cause scanning failures.
