Verify PDF 417 codes to ensure that they were printed properly and are scannable with a PDF 417 Verifier (also known as a PDF 417 Checker). PDF 417 symbols can link to other symbols, allowing more data to be stored amongst the two codes. However, both codes need to be formatted and printed correctly for this to work.
When checking the format of a PDF 417, elements such as modulation, minimum edge contrast, and defects, amongst other criteria are considered. These result in a verification grade, which will determine if the PDF 417 is readable on a barcode scanner.
PDF 417 codes can be checked by the Webscan verifiers below.
