How It Works
This application uses ZXing (Zebra Crossing), a powerful barcode scanning library, to detect and decode barcodes from images or your device camera.
For best results:
- Use clear, well-lit images or good lighting when using camera
- Ensure the barcode is in focus
- Position the barcode to be as straight as possible
- Hold the camera steady when scanning with device camera
- Supported formats: QR Code, Data Matrix, UPC, EAN, Code 128, Code 39, ITF, and more
Troubleshooting
If you're having trouble with barcode recognition:
- Image Quality: Make sure your image is clear, well-lit, and the barcode is in focus.
- Camera Position: When using the camera, hold it steady and ensure good lighting.
- Barcode Type: This scanner supports both 1D barcodes (EAN, UPC, Code128, etc.) and 2D barcodes (QR Code, Data Matrix).
- Orientation: ZXing can detect barcodes in various orientations, but straight alignment may improve results.
- Contrast: Ensure there's good contrast between the barcode and background.
- Size: The barcode should be a reasonable size in the image - not too small or too large.
- Different Image: If all else fails, try a different image of the barcode.
- Camera Permissions: Make sure you've granted camera permissions if using the camera feature.
