An ITF-14 bar code. The thick rectangular border is the Bearer Bar. ITF is often used for marking product ID numbers or other codes, of various lengths, on item cartons and multi-unit cases. One specific instance of this, standardized by GS1, is the ITF-14 bar code used to mark packages with Global Trade Item Numbers. In these uses, the ITF bar ...
A UPC barcode. The Universal Product Code (UPC or UPC code) is a barcode symbology that is used worldwide for tracking trade items in stores.. The chosen symbology has bars (or spaces) of exactly 1, 2, 3, or 4 units wide each; each decimal digit to be encoded consists of two bars and two spaces chosen to have a total width of 7 units, in both an "even" and an "odd" parity form, which enables ...
Then in 1987 it was standardized as JIS-X-0502, [2] a standard physical distribution barcode symbol ITF-14/16/6. The ITF barcode has an add-on version for displaying the weight, etc., and it is possible to encode a 5-digits numerical value and 6-th check character as ITF-6 [3] after ITF-14 or ITF-16 [4] (obsolete in 2010).
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.
By utilizing the barcode's center marker, a scanner can decode an International Article Number (EAN) by scanning one half of the barcode at a time through a helical scan at a 45-degree angle. This method reconstructs the full code from partial scans, useful when the barcode is obscured or damaged.
Each code, typically four or five digits long, offers information about the item's category (i.e., if it's a banana, an apple, or a peach), if it's organic or conventionally grown, and potentially ...
Example of Industrial 2 of 5 barcode. Industrial 2 of 5. [1] (also known as Standard 2 of 5 [2] [3] [4]) is a variable length, discrete, two width symbology. Industrial 2 of 5 is a subset of two-out-of-five codes. [5] Industrial 2 of 5 is one of the first 1D and oldest barcodes and can encode only digits (0-9).
They do not appear in the body of a Codabar string. The 16 possible combinations of start and stop symbol may be used to distinguish different applications. For example, the library barcode illustrated begins with A and ends with B. FedEx tracking number barcodes, on the other hand, begin with B and end with D.
