A document may look perfect.
But if the barcode doesn’t match – it’s an instant rejection.
▪ PDF417 / Code128
The code contains the same data as the visual zone.
Name, number, date – everything must match character by character.
▪ Check digits
Algorithms calculate the numbers automatically.
One mistake – and the file is flagged as invalid.
▪ Encoding logic
Format, field order, regional standards – the code is read as structure, not as a “picture”.
A barcode is not decoration.
It’s a digital duplicate of the document.
▸ If you think “it’s just stripes” – better double-check.
Message us – we’ll review the code before the system does.
