Common Mistakes to Avoid
Using EAN-13 with the wrong number of digits
Solution:
EAN-13 requires exactly 12 or 13 digits — check the format's requirements if generation fails.
Making bars too thin to scan reliably
Solution:
Increase bar width if the barcode will be printed small, so scanners can read it reliably.
