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.
ISO/IEC 19762-1 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 31, Automatic identification and data capture techniques.
This second edition cancels and replaces the first edition (ISO/IEC 19762-1:2005), which has been technically
revised.
ISO/IEC 19762 consists of the following parts, under the general title Information technology — Automatic
identification and data capture (AIDC) techniques — Harmonized vocabulary:
⎯ Part 1: General terms relating to AIDC
⎯ Part 2: Optically readable media (ORM)
⎯ Part 3: Radio frequency identification (RFID)

INTERNATIONAL STANDARD ISO/IEC 19762-1:2008(E)

Information technology — Automatic identification and data
capture (AIDC) techniques — Harmonized vocabulary —
Part 1:
General terms relating to AIDC
1 Scope
This part of ISO/IEC 19762 provides general terms and definitions in the area of automatic identification and
data capture techniques on which are based further specialized sections in various technical fields, as well as
the essential terms to be used by non-specialist users in communication with specialists in automatic
identification and data capture techniques.
2 Classification of entries
The numbering system employed within ISO/IEC 19762 is in the format nn.nn.nnn, in which the first two
numbers (nn.nn.nnn) represent the “Top Level” reflecting whether the term is related to 01 = common to all
AIDC techniques, 02 = common to all optically readable media, 03 = linear bar code symbols,
04 = two-dimensional symbols, 05 = radio frequency identification, 06 = general terms relating to radio,
07 = real time locating systems, and 08 = MIIM. The second two numbers (nn.nn.nnn) represent the
“Mid Level” reflecting whether the term is related to 01 = basic concepts/data, 02 = technical features,
03 = symbology, 04 = hardware, and 05 = applications. The third two or three numbers (nn.nn.nnn) represent
the “Fine” reflecting a sequence of terms.
The numbering in this part of ISO/IEC 19762 employs “Top Level” numbers (nn.nn.nnn) of 01.
