UPC-E1

This topic describes how to insert a barcode control of the UPC-E1 symbology (code type) into a report. In addition, it provides a short description of the UPC-E1 code type. To learn more about barcodes in XtraReports, see the Barcodes Overview topic.

UPC-E is a kind of UPC-A, which allows a more compact barcode by eliminating "extra" zeros. Since the resulting UPC-E barcode is about half the size of the UPC-A barcode, UPC-E is generally used on products with a very small packaging where a full UPC-A barcode doesn't fit.

The UPC-E1 is a variation of UPC-E code with the number system set to "1". In the human readable string of the bar code the first digit signifies the number system (always 1 for this code type), the last digit is the check digit of the original UPC-A code. So, in the example below, the original UPC-A code is "14210000526". We should remove the leading "1" when assigning the string to the control's property, since the code format itself implies its presence. The checksum digit (1) is calculated automatically, and the symbology algorithm transforms the rest of the numeral string. The result is 425261, and it is encoded along with the number system prefix and the check digit into the scanner-readable form.

Not every UPC-A code can be transformed into the UPC-E1. It must meet special requirements, and you may refer to UPC-E Symbology page for more information.

Since the number system "1" is not used in regular UPC-A codes, the UPC-E1 symbology use is uncommon.

The are no properties specific to the UPC-E1 barcode type.
