DataGroup1

internal final class DataGroup1 : DataGroup

Represents Data Group 1 (DG1) from an ePassport. DG1 contains information about the travel document.

The Data Elements of DG1 are intended to reflect the entire contents of the MRZ whether it contains actual data or filler characters.

Note

Details on the implementation of the MRZ are dependent on the type of LDS1 eMRTD (TD1, TD2 or TD3 formats).

Note

DG1 is required by the LDS of the eMRTD.

Note

The MRZ is duplicated within DG1 from the physical document.
