Industrial 2 of 5
Industrial 2 of 5. (also known as Standard 2 of 5) is a variable length, discrete, two width symbology. Industrial 2 of 5 is a subset of two-out-of-five codes.
Industrial 2 of 5 is one of the first 1D and oldest barcodes and can encode only digits (0-9). It was invented in 1971 by Identicon Corp. and Computer Identics Corp. At this time, it has only historical value because of low encoding density and restricted charset. Previously it was used for cardboard printing, photo developing envelopes, warehouse sorting systems and for management of physical distribution.
Industrial 2 of 5 has low encoding density because an information can be encoded only in black bars and white spaces are just ignored. Industrial 2 of 5 barcode may include an optional check digit. Most of barcode readers support this symbology.
Industrial 2 of 5 can encode digits from 0 to 9. The digit can be encoded in 5 black bars on digit and white spaces are ignored. Any black bar can have two width: wide or narrow. Any white space can have any width by not more than narrow black bar.
Industrial 2 of 5 start/stop patterns and data patterns are split by white space. Industrial 2 of 5 could include optional checksum character which is added to the end of the barcode.
Industrial 2 of 5 features:
Four bars in encoding scheme, except zero, have own weights which encode value of the symbol. Also, last black bar is used as parity bit to avoid single error. Symbol consists of five bars: two wide bars and three narrow bars. Value of the symbol is a sum of nonzero weights of first four bars.
As an example, we can see digit 3 is encoded. Weight 1 and 2 is not zero and parity bits is 0 means the count of bits is divisible on 2. The result: 1*1 + 1*2 + 0*4 + 0*7 = 3. The same with digit 4: weight 4 is not zero and parity bit is 1, which means that count of bits is not divisible on 2. 0*1 + 0*2 + 1*4 + 0*7 = 4.
