|
|
|The Code 16K (1988) is a multi-row bar code developed by Ted Williams at Laserlight Systems (USA) in 1992. In the US and France, the code is used in the electronics industry to identify chips and printed circuit boards. Medical applications in the USA are well known. Williams also developed Code 128, and the structure of 16K is based on Code 128. Not coincidentally, 128 squared happened to equal 16,384 or 16K for short. Code 16K resolved an inherent problem with Code 49. Code 49's structure requires a large amount of memory for encoding and decoding tables and algorithms. 16K is a stacked symbology.<ref name="2-Dimensional Bar Code Page">{{Cite web|url=http://www.adams1.com/stack.html|title=2-Dimensional Bar Code Page|website=www.adams1.com|access-date=12 January 2019|archive-date=7 July 2011|archive-url=https://web.archive.org/web/20110707082929/http://www.adams1.com/stack.html|url-status=live}}</ref><ref>{{Cite web|url=http://www.gomaro.ch/ftproot/Code%2016k.pdf|title=Code 16K Specs|website=www.gomaro.ch|access-date=12 January 2019|archive-date=13 July 2018|archive-url=https://web.archive.org/web/20180713121653/http://www.gomaro.ch/ftproot/Code%2016k.pdf|url-status=live}}</ref>

|A proprietary code developed by Electronic Automation Ltd. in 1981. It is possible to encode more than 100 numeric digits in a space of only 5mm x 5mm. User selectable error correction allows up to 40% of the code to be destroyed and still remain readable. The code is used in the pharmaceutical industry and has an advantage that it can be applied to products and materials in a wide variety of ways, including printed labels, ink-jet printing, laser-etching, indenting or hole punching.<ref name="2-Dimensional Bar Code Page"/><ref>{{cite patent|title=Machine readable binary codes|country=US|number=5825015|issue-date=20 October 1998|inventor-last=Chan|inventor2-last=GB|inventor-first=John Paul}}</ref><ref>{{Cite web|url=http://pdfpiw.uspto.gov/.piw?Docid=05825015&homeurl=http%3A%2F%2Fpatft.uspto.gov%2Fnetacgi%2Fnph-Parser%3FSect1%3DPTO2%2526Sect2%3DHITOFF%2526p%3D1%2526u%3D%25252Fnetahtml%25252FPTO%25252Fsearch-bool.html%2526r%3D1%2526f%3DG%2526l%3D50%2526co1%3DAND%2526d%3DPTXT%2526s1%3D5825015.PN.%2526OS%3DPN%2F5825015%2526RS%3DPN%2F5825015&PageNum=&Rtype=&SectionNum=&idkey=NONE&Input=View+first+page|title=US Patent 5825015|date=20 October 1998|website=pdfpiw.uspto.gov|access-date=12 January 2019|archive-date=13 January 2019|archive-url=https://web.archive.org/web/20190113062829/http://pdfpiw.uspto.gov/.piw?Docid=05825015&homeurl=http%3A%2F%2Fpatft.uspto.gov%2Fnetacgi%2Fnph-Parser%3FSect1%3DPTO2%2526Sect2%3DHITOFF%2526p%3D1%2526u%3D%25252Fnetahtml%25252FPTO%25252Fsearch-bool.html%2526r%3D1%2526f%3DG%2526l%3D50%2526co1%3DAND%2526d%3DPTXT%2526s1%3D5825015.PN.%2526OS%3DPN%2F5825015%2526RS%3DPN%2F5825015&PageNum=&Rtype=&SectionNum=&idkey=NONE&Input=View+first+page|url-status=live}}</ref>
