ChecksumValidation

Inheritance: java.lang.Object, java.lang.Enum

public enum ChecksumValidation extends Enum<ChecksumValidation>

Enable checksum validation during recognition for 1D and Postal barcodes.

Default is treated as Yes for symbologies which must contain checksum, as No where checksum only possible.

Checksum never used: Codabar, PatchCode, Pharmacode, DataLogic2of5

Checksum is possible: Code39 Standard/Extended, Standard2of5, Interleaved2of5, ItalianPost25, Matrix2of5, MSI, ItalianPost25, DeutschePostIdentcode, DeutschePostLeitcode, VIN

Checksum always used: Rest symbologies
