When printing the Interleaved 2 of 5 symbology (I 2 of 5 symbology), verify that the codes will scan with an Interleaved 2 of 5 Verifier (also known as an Interleaved 2 of 5 Checker).
Certain specifications for I 2 of 5 require bearer bars, which completely surround the symbol including the quiet zones. These bars must be a consistent thickness around the entire barcode. Other specifications require a MOD 10 check sum. These checksums are calculated the same way as a UPC checksum. Webscan’s verifiers will ensure that Interleaved 2 of 5 barcodes will scan throughout the supply chain according to ANSI standards.
Below is a verification report of a Interleaved 2 of 5 (I25) bar code from a Webscan verifier.
