III-2 Machine Readable Travel Documents
• ensure efficient and optimum facilitation of the rightful holder;
• ensure protection of details recorded in the optional capacity expansion technology;
• allow global interchange of capacity expanded data based on the use of a single LDS common
to all MRTDs;
• address the diverse optional capacity expansion needs of issuing States and organizations;
• provide expansion capacity as user needs and available technology evolve;
• support a variety of data protection options;
• utilize existing international standards to the maximum extent possible in particular the
emerging international standards for globally interoperable biometrics.
6. MANDATORY AND OPTIONAL DATA ELEMENTS
A series of MANDATORY and OPTIONAL Data Elements has been defined for the LDS to meet the global
requirements of processing persons presenting MRtds as illustrated in Figure III-1.
7. ORDERING AND GROUPING OF DATA ELEMENTS
7.1 A logical order 1 supported by ordered groupings of related Data Elements has been established for
the series of mandatory and optional Data Elements as illustrated in Figure III-1.
7.2 The ordered groupings of Data Elements are further grouped depending on whether they have
been recorded by: 1) an issuing State or organization; or 2) a receiving State or approved receiving
organization.
Note.—The ability for a receiving State or approved receiving organization to add data to the LDS
is not supported in the LDS defined in this edition of Doc 9303, Part 3.
7.3 Four groups of Data Elements MUST be included if an LDS is recorded to the optional capacity
expansion technology (contactless IC):
• those that define the contents of the machine readable zone (MRZ) of the eMRtd (Data
Group 1);
• an encoded image of the face of the eMRtd holder as defined in Volume 1 and Section II of
Volume 2 of Doc 9303, Part 3;
1. The logical order for Data Elements has been standardized to meet the global requirements established for enhanced facilitation and
improved security when processing persons presenting MRtds. The actual order of recording of the grouped Data Elements is defined
by specifications established to ensure efficient performance of the contactless integrated circuit expansion technology. These
specifications are defined in Appendix 1.
