Frequently Asked Questions

Can it read damaged QR codes?

QR codes have built-in error correction (up to 30%). Slightly damaged codes still read; heavily damaged ones fail.

Multiple QR codes in one image?

All detected QR codes are returned with their position. Useful for batch scanning of labels.

What about other barcode types?

pyzbar also reads Code 128, Code 39, EAN-13, UPC-A, etc. The decoder identifies the type automatically.
