CHECK
Validate the result
Scan the generated image with a phone camera or barcode application and verify every character of the decoded value.
LIMITS
Know the limits
QR output uses medium error correction and a fixed default margin, while Code 128 has character and practical length constraints. Successful generation does not guarantee readability on every printer or scanner.

FAQ
Frequently asked
Can I crop the margin or use low-contrast QR colors?
Heavy cropping and low contrast reduce recognition. Preserve a quiet zone around the symbol and use a dark code on a light background for reliable scanning.
