EAN/UPC

Are specified for retail Point-of-Sale (POS) because they are designed for the high volume scanning environment

Used at POS and in logistics must be printed larger than the "target" size to accommodate logistics scanning Limited to carrying

GS1 Keys and special identifiers for restricted applications like variable measure trade items and internal numbering

GS1 DataBar

A family of symbols that can be scanned at retail point-of-sale (POS), are smaller than EAN/UPC and can carry additional

information such as serial numbers, lot numbers of expiry dates. A subset of GS1 DataBar bar codes designed for use at

POS are being considered by a GS1 Board Task Force for future adoption because GS1 DataBar can carry all GS1 Keys and

attributes and do so in a smaller space than EAN/UPC GS1 DataBar symbols are already approved for global use on healthcare

items that do not cross POS

GS1-128 (previously referred to as UCC/EAN-128 or EAN-128)

GS1-128 (UCC/EAN-128) bar codes can carry all GS1 Keys and attibutes but cannot be used to identify items crossing POS

ITF-14

ITF-14 bar codes can only carry GTINs, can be printed directly on corrugated cartons,

but cannot be used to identify items crossing POS

GS1 DataMatrix

GS1 DataMatrix is the only "2D Matrix" symbol specified for use by GS1 and is becoming increasingly

the symbol of choice for many in healthcare Because GS1 DataMatrix

requires camera based scanners it is currently specified for healthcare items not crossing POS and direct part marking

Composite Component

Composite Component is the only "2D linear" symbol specified by GS1 It is called a component

because it is only used with a linear bar code like GS1-128 or RSS
