How to Scan QR codes on Your iPhone or Android

QR codes have become a seamless part of daily life, showing up on everything from menus and flyers to business cards and product packaging. As their use expands, knowing how to scan QR codes quickly and efficiently has become a valuable skill for both personal convenience and professional interactions.

Whether you’re using an iPhone or an Android device, this guide breaks down the best ways to scan QR codes and why it matters.

Scanning QR Codes on iPhone

Apple makes it easy to scan QR codes using the built-in Camera app and additional tools like Live Text.

Using the Camera App

Scanning QR codes with the iPhone Camera app is fast and intuitive:

• Open the Camera app from the Home screen, Control Center, or Lock screen

• Use the rear-facing camera and position it over the QR code

• Hold your phone steady until a notification pops up

• Tap the notification to open the link or view the QR content

The iPhone’s camera automatically detects QR codes, so there’s no need to press a button or activate a separate feature.

Using Live Text (iOS 15 and Later)

For QR codes embedded in photos or screenshots:

• Open the image in the Photos app

• Long-press on the QR code

• Tap the pop-up that appears to access the linked content

Live Text extends QR scanning to images, giving you flexibility when the code isn’t physically in front of you.

Scanning QR Codes on Android

Android users have several reliable options depending on their device model and software version.

Using the Camera App

Many Android phones can scan QR codes right from the native Camera app:

• Open the Camera app

• Point the camera at the QR code

• Wait for a banner or link to appear

• Tap the notification to open the content

If nothing happens, your phone may not support automatic QR scanning.

Using Google Lens

For phones without built-in support:

• Open the Google app and tap the Google Lens icon

• Point the camera at the QR code

• Tap the screen when the code is detected

• Follow the prompt to open or copy the content

Google Lens is a powerful, free tool that expands your phone’s scanning abilities.

Using Third-Party Scanner Apps

If you need additional functionality or compatibility:

• Download a trusted QR scanner from the Google Play Store

• Open the app and grant the necessary permissions

• Point the camera at the QR code

• Let the app scan and display the result

These apps can also help scan barcodes or perform batch scans in retail or event settings.

Scanning QR Codes from Saved Images

If a QR code is already in your photo library or on your screen, you can still scan it easily.

Method 1: Use Online QR Code Readers

For both iPhone and Android:

• Save or screenshot the QR code image

• Open a mobile browser and visit a reputable online QR code reader

• Upload the image

• Wait for the code to be processed

• Copy or interact with the decoded information

This method is helpful for scanning codes found on websites or within digital documents.

Method 2: Long-Press on Gallery Images

Some phones support scanning directly from the gallery:

• Open your gallery or photo app

• Locate the image with the QR code

• Press and hold on the code

• If supported, a link will appear with the option to open it

This feature is available on newer models and varies by device manufacturer.

Troubleshooting QR Code Scanning

If your device struggles to scan a QR code, try the following:

• Improve lighting: QR codes need to be well-lit to register clearly

• Clean the lens: Dust or smudges can affect camera focus

• Hold steady: A shaky hand can cause scanning delays

• Adjust distance: Try moving your phone closer or farther from the code

• Check code quality: Blurry, damaged, or low-resolution codes may not work

These simple adjustments often solve common scanning issues.

How QR Code Technology Works

Understanding how QR codes work adds insight into their versatility:

• Data encoding: The information is converted into a binary pattern

• Square modules: Black and white squares represent data bits

• Positioning markers: Three large corner squares help with orientation

• Error correction: Built-in safeguards allow partial codes to still be readable

• Scanning: Your device translates the pattern into usable information like URLs or contact details

QR codes can store data such as website links, business contact info, event details, or Wi-Fi credentials.
