ChecksumValidation

Permite validarea checksum în timpul recunoașterii pentru codurile 1D și Postal.

Default este tratat ca Da pentru simboluri care trebuie să conțină checksum, ca Nu unde checksum numai posibil.

Checksum nu a fost folosit niciodată: Codabar, PatchCode, Pharmacode, DataLogic2of5

Checksum este posibil: Code39 Standard/Extended, Standard2of5, Interleaved2of5, ItalianPost25, Matrix2of5, MSI, ItalianPost25, DeutschePostIdentcode, DeutschePostLeitcode, VIN

Checksum întotdeauna folosit: simboluri de odihnă

[XmlSerialization(Type = XmlSerializationType.Element)]
public ChecksumValidation ChecksumValidation { get; set; }
