UpcASymbology Class
Represents a barcode symbology implementation for UPC-A.
public class UpcASymbology : EanUpcSymbologyBase- Inheritance:
- object ObservableObjectBase BarcodeSymbologyBase LinearBarcodeSymbologyBase EanUpcSymbologyBase object
Remarks
UPC-A (Universal Product Code) is the standard retail barcode symbology used in the United States and Canada. It encodes a 12-digit number consisting of a number system digit, manufacturer code, product code, and a check digit.
The value provided should be either 11 digits (the check digit is auto-calculated and appended) or 12 digits
(the provided check digit is validated). Only digits 0-9 are supported.
UPC-A is technically equivalent to EAN-13 with a leading 0. The encoding uses the same structure:
a start guard, 6 left-hand digits encoded with L-codes (odd parity), a center guard,
6 right-hand digits encoded with R-codes, and an end guard.
The EAN-13-specific implementation is available in Ean13Symbology.
This symbology supports optional 2-digit and 5-digit add-on supplements via a supplement value in the encoding request.
