What is Barcode ?
Types of Barcode ?
1. One dimensional (1D) Barcode :
It is also
known as linear barcode. Originally it is prepared by changing width and
space of parallel lines
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
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.
Aztec Code, Data Matrix, EZcode, High capacity color barcode, MaxiCode,
NexCode, PDF417, Qode, QR code, ShotCode, SPARQCode etc.
What is Symbologies ?
1D Symbologies :
2D Symbologies :
What is Scanner or Barcode reader ?
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 :
For 2D :
What is Pharmacode ?
Encoding of 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 ?
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 ?
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 ?
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.
What is ITF Barcode ?
Barcode is Interleaved Two of Five ( Interleaved 2 of 5 ) barcode
system. ITF is continuous two width barcode symbology for encoding
