Interleaved 2 of 5 (ITF) is a continuous two-width barcode symbology encoding digits. It is used commercially on 135 film , for ITF-14 barcodes, and on cartons of some products, while the products inside are labeled with UPC or EAN .
0*3=0 5*9=45 4*3=12 1*9=9 5*3=15 ----- 81 % 10 = 1 Once you have the checksum digit, you can look up the structure in the following table. Note that the checksum digit is not in the final 5 digits, and is not intended to validate the 5 digit data, but rather to validate the reading of the EAN-5 overall.

Encoding EAN-13 Encoding L-digits Encoding G-digits Encoding R-digits. The barcode consists of 95 areas (also called modules [citation needed]) of equal width. Each area can be either white (represented here as 0) or black (represented as 1). From left to right: 3 areas for the start marker (101)
Plessey Code is a 1D linear barcode symbology based on pulse-width modulation, developed in 1971 by The Plessey Company plc, a British-based company. [1] It is one of the first barcode symbology, and is still used rarely in some libraries and for shelf tags in retail stores, in part as a solution to their internal requirement for stock control ...
When FNC2 is in the final data position, [2]: 5.2.1.2 then the preceding two message characters, digits and uppercase letters in order 1 to 9 then A to Z (for values 10 to 35) shall as "m" and "n" designate where this message belongs in a "m out of n" sequence. As an example, a symbol whose message ends "4 B FNC2" shall be the 4th symbol out of ...
Code 93 is a barcode symbology designed in 1982 by Intermec to provide a higher density and data security enhancement to Code 39. It is an alphanumeric, variable length symbology. It is an alphanumeric, variable length symbology.
Han Xin Code finder pattern. Finder Pattern [3]: 4.2.3 consists from four Position Detection Patterns located at the four corners of the barcode. The size of Position Detection Pattern is 7×7 modules and it is constructed from 5 elements: dark 7 × 7 modules, light 6 × 6 modules, dark 5 × 5 modules, light 4 × 4 modules, dark 3 × 3 modules respectively.
