Supported formats and limits

The reader uses the browser's native Barcode Detection API when available and lazy-loads a locked local ZXing fallback only after you choose an image or start the camera. Typical formats include UPC-A/E, EAN-8/13, Code 39, Code 128, ITF, Codabar, Data Matrix, PDF417, Aztec and QR. Exact support varies by browser and image quality.

A decoded number is not a product-directory lookup and does not prove ownership, authenticity or GS1 registration. No uploaded image or camera frame is sent to TNAADO.
