What Is a QR Code?

A QR code (Quick Response code) is a type of two-dimensional barcode that stores data such as URLs, text, contact details, or authentication tokens. When scanned, the phone decodes the information instantly and displays the result.

A detailed explanation of how QR codes work, including their structure and real-world use cases, is available in this QR Code overview on Wikipedia.

Can Android Phones Scan QR Codes Natively?

Yes. Most modern Android phones can scan QR codes without installing any extra app. Android supports QR scanning through:

• Built-in Camera apps (on many devices)
• Google Lens (available on almost all Android phones)
• Google Photos (for scanning QR codes from images)

These methods are officially supported by Google and follow Android security and privacy standards.

Many Android phones now support QR code scanning directly from the Camera app.

1. Open the Camera app on your Android phone
2. Point the camera at the QR code
3. Hold steady for 1–2 seconds
4. A notification or link appears on the screen

Google Lens is the most reliable and universal method to scan QR codes on Android.

Steps:

1. Open Google Lens (from Google app, Camera, or app drawer)
2. Point your camera at the QR code

If the QR code is saved as an image or screenshot, you can still scan it easily.

2. Select the image containing the QR code
3. Tap the Google Lens icon
4. The QR code is scanned instantly

Google confirms image-based QR scanning support in its Google Photos help documentation.

Method 4: Scan QR Code from Chrome Browser (Links Only)

If a QR code opens a web link, Chrome can help generate and interact with QR codes.

While Chrome mainly focuses on creating QR codes, Google’s official Chrome documentation explains how QR codes are used for quick sharing.
This method is limited but useful for link-related QR actions.

Method 5: Use an Online QR Scanner (Optional)

If your phone camera does not support QR scanning, you can use browser-based tools.
