upc-e barcodes and zero suppression
A UPC-E barcode is actually an EAN-13/UPC-A barcode that has had certain digits removed to create an 8 digit number. Only certain EAN-13/UPC-A barcodes can go through this process.
For example, the UPC-A barcode “023456000073 ” can be suppressed to the UPC-E value “02345673” and restored to it’s original value by the barcode reader. The Softek barcode Reader SDK can interpret a UPC-E barcode in either format via theConvertUPCEToEAN13 property.
A useful description of the suppression process can be found on the IDAutomation web site.
