ITF-14 (Interleaved 2 of 5) is the barcode used on shipping containers and outer cases that hold multiple retail units.
The most striking feature of an ITF-14 is the thick black border (Bearer Bars). These bars serve two purposes: they equalize the pressure of the printing plate and prevent "short scans" where the laser only crosses a portion of the code.
ITF-14 barcodes are designed to be scanned from a distance and in motion, making them perfect for automated conveyor belts in sorting facilities and distribution centers.
ITF-14 is for logistics only; it is not intended for scanning at the retail point of sale.
