BS ISO IEC 19762-2 pdf – Information technology — Automatic identification and data capture (AIDC) techniques — Harmonized vocabulary
This part of ISO/IEC 19762 provides terms and definitions unique to optically readable media (ORM) in the area of automatic identification and data capture techniques. This glossary of terms enables the communication between non-specialist users and specialists in ORM through a common understanding of basic and advanced concepts.
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 02, 03, and 04.
3 Terms and definitions 02.01.01 optically readable medium ORM member of the set of automatic identification techniques such as a linear bar code, two-dimensional, mark sense, or optical character recognition (OCR) symbols, that are illuminated by a light source and examined by an optical detector that converts the received reflectance into electrical signals that are grouped in a predetermined method, recognized by the reader and converted into the corresponding computer code 02.01.02 symbology standard means of representing data in optically machine readable form NOTE Each symbology specification sets out its particular rules of composition or symbol architecture. 02.01.03 bar code symbol combination of symbol characters and features required by a particular symbology which together form a complete scannable entity
