Most barcode symbologies require a calculated check character or checksum digit
at the end. Some require two. These special characters allow the barcode
scanner to verify that the barcode is not miss-scanned. It guarantees
that the barcode is interpreted correctly every time.
But don't worry. Bars & Stripes takes care of all that for you. For all of
the symbologies Bars & Stripes supports, check character calculations are
performed according to specifications and the character is added at the end of
your barcode automatically.
But if you're curious to see how we calculate the various check characters,
we've provided these handy calculators.
