Frequently Asked Questions
How does a barcode scanner work?
The scanner emits light (laser or LED) onto the barcode. Dark bars absorb light, white spaces reflect it. A sensor detects the reflected pattern and converts it to electrical signals. Software decodes the width pattern into the encoded number or text.
Can I scan barcodes with my phone camera?
Yes. Modern smartphones can scan 1D barcodes (UPC, EAN, Code 128) and 2D codes (QR, Data Matrix) using the camera. The tool uses your device camera to read barcodes in real time and displays the decoded data instantly.
What barcode types can the scanner read?
The scanner supports: UPC-A, UPC-E, EAN-13, EAN-8, Code 128, Code 39, Code 93, ITF, Codabar, QR Code, Data Matrix, PDF417, and Aztec. It auto-detects the barcode type and displays the format alongside the decoded data.
Why is my barcode not scanning?
Common issues: poor lighting (too dark or glare), barcode too small or damaged, camera too close or far, blurry image, low print quality, or insufficient contrast. Ensure the barcode is flat, well-lit, and the camera is focused. Try adjusting distance.
How do I scan a barcode from an image file?
Upload the image containing the barcode to the tool. It processes the image, detects barcode regions, and decodes them. Supports JPG, PNG, and GIF formats. The image should have clear contrast and the barcode should not be distorted or partially obscured.
