📚 How Fake Barcode Detection Works
Checksum Verification: Every valid barcode has a mathematically calculated check digit. If it doesn't match, the barcode is definitely fake.
Quiet Zone Analysis: Genuine barcodes have required clear margins (quiet zones) on all sides. Missing margins indicate poor printing or copying.
Edge Sharpness: Professional barcode printing produces sharp, clean edges. Blurry or jagged edges suggest counterfeiting.
Pattern Recognition: Different barcode types have specific start/stop patterns and character encodings that must be followed.
Module Width Consistency: Genuine barcodes have consistent bar/space widths. Variations indicate printing problems or forgery.
⚠️ Important Notes
Best Results: Use clear, well-lit images of barcodes. Avoid blurry or low-resolution images.
Limitations: Severely damaged or distorted barcodes may not decode correctly. This tool provides probabilistic assessments, not definitive proof.
Supported Formats: EAN-13, EAN-8, UPC-A, UPC-E, Code 39, Code 128, and basic QR codes.
