Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to ISO/IEC 18013-3:2009 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 17, Cards and personal identification.
It describes the optional 1 line MRZ as a further machine readable technology option to the scanning area
identifier.

8.3.2.5 SAI consisting of an IDL MRZ
8.3.2.5.1 General
This mechanism is a 1 line MRZ and is used with the non-match alert or BAP mechanisms, which collectively
are applicable to SICs, 2D barcode, magnetic stripe and optical memory (see 8.4 and 8.5).
The IDL MRZ differs from the manner in which an input string is identified in 8.3 in that its position is fixed and
consequently does not require one or more graphical elements that demarcate the input string as an SAI.
The data elements shall be printed in machine readable form, in the MRZ, beginning with the left most
character position in each field in the sequence indicated in the data structure specifications for the IDL MRZ.
NOTE The content of the IDL MRZ should not be confused with data elements in the passport MRZ.
Check digits are used within the machine readable zone to provide verification that the entered data are
correctly interpreted.
The presence of the IDL MRZ is identified as follows:
a) If SIC access is required and the access conditions are unsatisfied (i.e. BAP is in place), the reader
searches for the IDL MRZ on the IDL.
b) If access to DG12 is available, BAP is not applicable and the non-match alert mechanism is present,
DG12 may confirm the existence of the IDL MRZ, alternatively, the reader searches for the IDL MRZ
on the IDL.
Not more than one IDL MRZ shall be present on a single IDL.

The reference string shall be encoded in accordance with ISO/IEC 8859-1.
The IDL MRZ may be located on the portrait side or the non-portrait side of the IDL, except for the case where
the reference string for the non-match alert is stored in a bar code. In such case the IDL MRZ shall not be
located on the same side as the barcode.
Figure Amd.1-1 shows the location of the 1 line MRZ at the bottom of the IDL, the nominal dimensions and
position of the IDL MRZ data.

8.3.2.5.2 Printing
The position of the left edge of the first character of the OCR line shall be 4.0 ± 1.0 mm (0.16 ± 0.04 in) from
the left edge of the IDL. The reference centre line for the OCR line shall be 7.27 ± 1.0 mm (0.29 ± 0.04 in)
from the bottom edge of the IDL. The OCR line shall not exceed the printing zone length of 77.7 ± 1.0 mm
(3.06 ± 0.04 in). No other printing in the B900 infrared band defined in ISO 1831 may appear in the machine
reading zone within 12.12 ± 1.0 mm (0.48 ± 0.04 in) from the bottom edge of the IDL.
Machine readable data shall be printed in OCR-B type font, size 1, constant stroke width. The MRZ shall be
printed with a horizontal printing density of nominally 10 characters per 25.4 mm.
The text shall be limited to the set of ICAO MRZ characters, i.e.: 0 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K L M
N O P Q R S T U V W X Y Z <, excluding the space character.
The IDL MRZ shall be adapted for reading in the B900 infrared band defined in ISO 1831. Under such
illumination the printing background and any overlays will backscatter light in a homogeneous way (i.
