TDType

public enum TDType : String, CaseIterable

An enumeration representing the type of a travel document (TD) based on the Machine Readable Zone (MRZ) structure.

According to the ICAO Document 9303 and ISO/IEC 7810 standard, there are three standardized document types depending on the position and the size of the MRZ within the physical document.

Note

MRZ is duplicated within the DataGroup1 from the physical smart card.
