ChecksumValidation

Umożliwia weryfikację czeku podczas rozpoznawania kodów 1D i pocztowych.

Podstawowe jest traktowane jako Tak dla symboli, które muszą zawierać czeki, jako Nie, gdzie czeki są tylko możliwe.

Checksum nigdy nie używany: Codabar, PatchCode, Pharmacode, DataLogic2of5

Przegląd jest możliwy: Code39 Standard/Extended, Standard2of5, Interleaved2of5, ItalianPost25, Matrix2of5, MSI, ItalianPost25, DeutschePostIdentcode, DeutschePostLeitcode, VIN

Checksum zawsze używane: symbole odpoczynku

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