Ideal for small packages because of its data compression. It contains the same information as the UPC-A except that there are minimum 4 zeros, which are suppressed. It reduces the number of digits from 12 to 6. BarDIMM Pro and BarDIMM Box accept the Zero Suppressed version of UPC-E in both versions of data, compressed and uncompressed. If data comes uncompressed, BarDIMM Pro and BarDIMM Box will perform automatically the compression.
A digit is described by 2 bars and 2 spaces and its width is calculated as 7 thin bars. Note that caption text below the barcode can be activated to verify checksum calculation.
