Barcode-Glossary

2 of 5 Industrial

Origin

The Code 2 of 5 Industrial was developed in 1968 by the Identicon Corporation.
The code 2 of 5 Industrial belongs to the code family 2 of 5, still mainly consisting of the codes "2 of 5 Interleaved" and "2 of 5 Matrix".

Furthermore, there are a few more variants that have more or less prevailed.

Symbol Designations

The Code "2 of 5 Industrial" is sometimes also called

  • 2 of 5 Industrial (VBCD: 2 of 5 Industrial) or
  • 2/5 5 Bars Industry.

These two digits, 2 and 5, express that each Barcode Character consists of 2 wide Elements, with altogether 5 elements.

Areas of Application & Branches of Trade

  • Department stores
  • Airline tickets
  • Photography business
  • The employment of code 2 of 5 Industrial has strongly decreased.

Classification

Advantages / Potencies

Disadvantages / Shortcomings

Codeable Character Set / Font

  • Digits 0 1 2 3 4 5 6 7 8 9
  • The 1Start character is automatically generated by the "Visual Bar Code Designer" (start pattern).
  • The 1Stop character is automatically generated by the "Visual Bar Code Designer" (stop pattern).

Symbol Properties

  • Code type: discrete (the Space – intercharacter gap – between the single Characters contains no information. Not only the intercharacter gaps but all spaces carry no information!
  • Elements per symbol character: 5, 2 wide ones and 3 narrow ones, displayed in form of 5 bars.
  • Self-checking characters: yes (the characters are intrinsically safe, meaning that a change within the character is detected to be an error).
  • Symbol Width: variable (the number of data characters within the symbol can, depending on existing agreements, be variable or variable up to a defined maximum).
  • Ratio (ratio between wide and narrow elements): The ratio should range between 2.0 : 1 and 3.0 : 1.
  • Bi-directionally readable: yes (the barcode symbol can be read in two directions, i.e. forwards or backwards).
  • Check Character: an optional check character (by using a check character – symbol check digit – substitution errors can nearly all be detected).
  • Character Density: 12 to 14 modules for each data character, according to the ratio between wide and narrow elements.
  • Necessary characters that contain no functional information: 15 to 19 modules, according to the ratio between wide and narrow elements Element.

Check Digits & Data Security

The five Elements each consist of 2 wide and 3 narrow elements. That way, each character of the code 2 of 5 Industrial is Self-Checking and thereby already guarantees a high level of security against Misread

In case of applications that require a high level of Data Security, a Symbol Check Digit has to be entered immediately after the last data character and directly before the Stop Pattern (stop character - will be automatically generated by the "Visual Bar Code Designer", if necessary).

Symbol Descriptions

EiA symbol – starting from the left – consists of:

  • one leading Quiet Zone
  • one Start Character (start pattern)
  • one or more Symbol Characters, representing data
    (including the optional Symbol Check Digit, that is automatically generated by the "Visual Bar Code Designer", if necessary)
  • one Stop Character (stop pattern)
  • one closing quiet zone
  • Klarschriftzeile (Human Readable Text)
    A human readable translation of the data characters encoded in the symbol (and possibly the check digits) should usually be printed along with the symbol. The size of the characters and the font type are not specified. As long as the quiet zones are not touched, the human readable text can be printed at any given spot near the symbol. Usually, the human readable text is situated below the symbol.
