Your Android device can scan any barcode or QR code thanks to a free app from the Play Store. Once you have installed the barcode scanning app, the device's camera can be used as a scanner. After that you can take different actions depending on the content of the barcode.

Part 2 of 3: Scanning a barcode
Step 1. Point your camera at a barcode
Step 2. Make sure the barcode is well lit
The scanner will have a hard time reading the barcode if it is too dark.
Step 3. Make sure the full QR code is visible in the viewfinder
Make sure the entire square code fits into the square on your screen.
Step 4. Make sure traditional barcodes appear in your viewfinder
When scanning a traditional barcode, the viewfinder should be perpendicular to the lines of the barcode.
Step 5. Adjust the distance between the camera and the barcode
This can help focus when the barcode is unclear.
Step 6. Hold the device steady while the barcode is scanned
When the scan is successful, the device will vibrate and you will hear a beep.
Part 3 of 3: Taking actions
Step 1. View the barcode information
After you scan a code you will see the type of information it contains. This can range from text to the URLs of websites. The content will be displayed at the top of the screen.
Step 2. Click an action button to take an action
The available actions will depend on the type of code you scanned.
- For example, if the scanned code is for the address of a website, you can press the Open button to open the website in your browser. You can also press the Share button to send it to someone.
- If you scan a contact you will be able to add or share it to the contact list.
- If you have scanned a product you will sometimes be able to search for the product or on the internet. Search for product will search for stores that sell this product.
- If you have scanned a calendar event, you can add it to your calendar.
Step 3. Troubleshoot codes not working
QR codes can contain all kinds of different links and content. Traditional barcodes contain only one number. This number can be associated with a product if it is popular. If the barcode was developed for a specific store or local business, it will usually only contain meaningless numbers.
