What is Barcode ?

Barcode is machine readable representation of information related to product to which it is attached.

Types of Barcode ?

Barcodes are of two types i.e. 1D and 2D

1.       One dimensional (1D) Barcode : 

                                                            It is also
known as linear barcode. Originally it is prepared by changing width and
space of parallel lines

Ex.
Codabar, code 25, Code 11, Code 39, Code 93, Code 128, CPC Binary, DUN
14, EAN 2, EAN 5, EAN 8, EAN 13, Facing Identification Mark, GS1-128,
Intelligent Mail Barcode, ITF 14, JAN, KarTrak ACI, Latent image
barcode, MSI, Pharmacode, PLANET, Plessey, PostBar, POSTNET, Telepen
etc.

2.       Two dimensional (2D) Barcode : 

                                                            2D code is a
matrix code to represent information in two dimension. It
represent more information as compared to One dimensional (1D) Barcode.

Ex.
Aztec Code, Data Matrix, EZcode, High capacity color barcode, MaxiCode,
NexCode, PDF417, Qode, QR code, ShotCode, SPARQCode etc.

 

What is Symbologies ?

Mapping between barcode and messages is known as symbology.

1D Symbologies :

                            It is also known as linear symbologies  which is read by laser.

2D Symbologies :

                           It is known as 2D Symbologies is read by digital camera.

 

What is Scanner or Barcode reader ?

Scanner
or Barcode readers have the ability to decode barcodes to obtain
information from it. Like RS-232, Keyboard Interface Scanners, USB
Scanners and now days many mobile phone come with barcode scanner by
utilizing mobile camera and many apps support barcode scanning like
Google goggles,  mbarcode etc

 

Barcode Verifier Standards

For 1D or linear :

                              ISO/IEC 15416

For 2D :

                ISO/IEC 15426-2

 

What is Pharmacode ?

Pharmacode is also called as Pharmaceutical Binary Code. It is used in Pharma industry to control packing system.

Encoding of Pharmacode

Pharmacode
contain a single value from 3 to 131070. Pharmacode can be read from
left to right or right to left. Narrow bar in pharmacode shows 2ⁿ and wide bar show 2*2ⁿ where n is bar position starting from 0 at right position.

 

What is Data Matrix ?

It
is two dimensional matrix barcode that contain black & white
modules or cells  arranged in square or rectangular pattern. Data Matrix
store text as well as numeric data. Some error correction codes are
used in data matrix to increase its reliability. Data Matrix have the
ability to store upto 2335 alpha-numeric characters.

 

What is QR Code ?

It
is Quick Response Code. QR Code become more popular due to its fast
readability and more storage capacity as compared to the standard UPC (
Universal Product Code ) barcodes.

 

What is GTIN ?

It
is Global Trade Item Number developed by GS1 for trade items. GTIN
number may be encoded in EAN 8, EAN 13, UPC A, UPC E and other barcodes
in GS1 system.

UPC = Universal Product Code

EAN = now  International Article Number originally European Article Number

 

What is ITF Barcode ?

ITF
Barcode is Interleaved Two of Five ( Interleaved 2 of 5 ) barcode
system. ITF is continuous two width barcode symbology for encoding
digits.
