QR codes, those pixelated black and white squares, are popping up everywhere nowadays. Once used primarily for industrial tracking purposes, QR codes are now scannable gateways to online content and apps. With the right decoder, all you need to access these convenient shortcuts is a quick scan on your Android device‘s camera.
Scanning QR codes on your Android opens up many intriguing possibilities. You can scan a code to:
- Visit a website
- Watch a video
- Download an app
- Pay for a product or service
- Retrieve contact details to connect with someone
- Unlock special content or experiences both online and offline
As QR code usage proliferates, knowing how to scan them on your Android ensures you don‘t miss out on all this functionality. The scanning process only takes seconds too!
In this comprehensive guide, you‘ll learn several methods for scanning QR codes using your Android device and camera. Let‘s dive in!
A Brief History of QR Codes
Before learning how to scan, let‘s briefly travel back in time to understand how QR codes came to be.
QR codes were invented in 1994 by the Japanese company Denso Wave. The "QR" in the name stands for "quick response," reflecting how rapidly the coded information can be scanned and processed.
Denso Wave originally designed QR codes to track vehicle parts in manufacturing plants. However, marketers soon realized QR codes provided a fast way for consumers to access digital content.
When smartphones with cameras appeared in the late 2000s, QR codes began popping up everywhere as scannable shortcuts to websites, videos, special offers, and more.
Now with billions of QR code scans conducted globally each year, it‘s clear these ingenious pixelated squares are here to stay!
Benefits of Scanning QR Codes on Android
With the ability to encode different types of data like URLs, text, images, and contact info into a tiny space, it‘s no wonder QR codes have become so popular.
Scanning QR codes on your Android device provides many advantages, including:
Convenience – Rather than manually typing in a long URL or contact details, you can access the information almost instantly with a quick scan.
Engaging Experiences – QR codes drive scanners to rich online content, lead to real-world rewards, or unlock interactive experiences.
Contactless Transactions – Instead of exchanging payment cards or cash, a seller can display a scannable QR code to safely and seamlessly receive payment.
Information On-Demand – Museums, transit systems, stores, and events display QR codes to provide supplementary content to interested visitors.
Brand Connection – Marketers incorporate QR codes in advertisements, product packaging, and promotions to engage consumers.
Clearly, you gain a lot from learning how to scan QR codes on Android! Now let‘s get right to it.
Method 1: Scanning QR Codes with Your Camera App
If your Android device runs on version 8.0 or higher, you likely have a built-in QR code scanner in your camera app.
Here‘s how to use it:
Open Your Camera App
The first step is accessing your camera app. Depending on your Android model, you may:
- Swipe up from the bottom to reveal all apps, then select the camera icon
- Swipe left or right to scroll through apps on your home screen and tap on your camera app
- Or simply tap on a camera icon already on your home screen
Position Your Camera to Focus on the QR Code
With your camera app open, point your phone‘s lens at the QR code while ensuring:
- You have good lighting conditions
- The QR code takes up most of the camera frame
- All 4 corners of the code are clearly visible
Your phone will automatically detect and scan the QR code.
Follow Onscreen Prompts After Scanning
What happens next depends on the type of data encoded in the QR code:
- For a website URL, you‘ll see the address pop up on screen with options to open the link in your browser, copy the URL, or share it.
- If it‘s contact information, you may be prompted to add it to your address book.
- For an app download, tapping may begin setup in the Play Store.
- Scanning a payment QR may open your wallet app to complete the transaction.
Essentially your Android will process the QR code data and display relevant follow-up options to utilize the information. Pretty magical!
And that‘s all there is to scanning QR codes with newer Android camera apps! Next let‘s look at options if your device lacks this baked-in scanning functionality.
Method 2: Scanning QR Codes with Google Lens
Google Lens is an image recognition tool from Google that can also scan and interpret QR codes embedded in photos.
Accessing Google Lens to scan QR codes is easy with these steps:
Open Google Lens
You have a few options to initially open Google Lens:
Through the camera app – If available, tap "Modes" then select Google Lens
Via Google Assistant – Activate your voice assistant then say "Open Google Lens"
In the Google app – Tap the rainbow colored Google Lens icon
Within Google Photos – Open the photo containing your QR code, then tap the Google Lens icon
Scan Your QR Code
Once Google Lens opens, just point your camera viewfinder at your QR code to trigger scanning.
Much like directly scanning with the camera, the app will analyze the QR code data and present relevant actions to take.
You may also see some informational overlays about the QR code or encoded URL appear on screen after scanning with Google Lens.
If for some reason Google Lens isn‘t working properly with your camera, double-check that "Google Lens suggestions" is enabled in your camera settings.
Now let‘s look at one final option for decoding QR codes on Android…
Method 3: Using a Third-Party QR Scanner App
If your Android device is older or doesn‘t include integrated scanning capabilities, downloading a QR code reader app is your best bet.
The Google Play Store offers many reliable, free scanner apps to help you get the job done.
Popular options include:
-
QR Code Reader – One of the highest rated barcode and QR scanners with over 100 million installs
-
Barcode Scanner – A longtime favorite app for scanning all types of barcodes
-
QR & Barcode Scanner – As the name suggests, easily scans QR codes and 1D/2D barcodes
Let‘s use QR Code Reader as an example to walk through installing and utilizing a third-party app:
Download and Install Your Chosen App
- Open the Play Store on your Android device
- Search for "QR Code Reader" (or your preferred app)
- Tap "Install" to download the app
- Tap "Accept" to grant the app permission to access your camera for scanning
Open the App and Scan Your QR Code
- Tap to open your newly installed QR Code Reader app
- Point your camera at the QR code until scanned
- Take any suggested actions presented after decoding
And done! The app does the tough work translating that QR mosaic into something meaningful for you.
Troubleshooting Issues Scanning QR Codes
Given how rapidly QR code scanning occurs, you may be surprised to encounter issues occasionally.
Here are some potential problems and fixes:
QR code not scanning? First, double check your camera focus and lighting. Move closer or further away. Try scanning from multiple angles. If still failing, the code itself may be damaged or encoded incorrectly.
Scanned code doesn‘t open a link? The URL or website associated with the code may no longer be active. Notify the code creator if possible.
Scanned code opens unwanted content? Stop engagement. Uninstall any downloaded apps immediately. Report fraudulent or dangerous QR codes to the proper authorities.
Scanning feels buggy? Try restarting your Android device or reinstalling your QR scanner app for a fresh start.
Still having trouble? Search for your specific scanning error message online for helpful tutorials or contact customer support.
Hopefully these troubleshooting tips get your QR code scanning back on track!
The Many Creative Uses for QR Codes
Beyond pointing your phone‘s camera at a QR code printed on a random advertisement or product package, there are many creative ways QR codes are being implemented:
Interactive Restaurant Menus – Rather than browsing grubby physical menus during COVID, restaurants adopted scannable QR code menus accessed right from diners‘ phones.
Informative Museum Exhibits – Museums attach QR codes to exhibits providing supplementary content like audio, video, and historical facts.
Transit Ticketing – Rail systems and airlines utilize scanable QR codes on digital tickets for contactless, convenient boarding.
Product Authentication – High-end goods embed certification QR codes which buyers scan to verify authenticity and learn about manufacturing origins.
Contact-Free Business Cards – Professionals now often connect by sharing virtual business cards with QR codes linking to their websites, social profiles and contact info.

Secure Events Access – Rather than paper tickets, conferences and conventions issue attendee wristbands with scannable QR entry codes.
Elaborate Marriage Proposals – Romantics integrate QR code riddles leading their partners eventually to the big "Will you marry me?" question.
As you can see, QR codes open up boundless creativity both online and offline thanks to the myriad types of scannable information they can embed!
Security Considerations When Scanning QR Codes
While QR codes certainly make life more convenient, you must exercise some caution too.
Malware Risks – Criminals can direct unsuspecting scanners to malicious sites distributing malware. Only scan codes shared from trusted sources.
Phishing Schemes – Fraudsters masquerade as legitimate businesses with QR codes sending victims to convincing but fake sites capturing login credentials and payment information.
Unexpected Charges – Unethical retailers present QR codes that trigger unwanted subscriptions, text message charges or large downloads deducting from customers‘ phone plan data and device storage limits.
Location Tracking – QR codes associating scanned IDs with geolocations can compromise privacy if data falls into the wrong hands.
Until QR code safety standards evolve, individuals need to stay vigilant. Double check the URLs of scanned sites for any sign of suspicious activity. Avoid entering sensitive personal information after scanning.
You can also run scans through tools like QR Code Monkey or ScanGuard to detect if codes have malicious redirects baked within before engaging.
