EAN 13. Usage.

see the previous part here


Widely used in Europe on consumer goods such as groceries, DVDs, food items and other similar products.
Used in production houses where fast encoding and decoding is required owing to its simpler encoding/ decoding technique involving numeric only.
Due to its capability to be scanned at acute angles, EAN-13 is widely used on point of sales retail stores.


Code13 barcode type should be used in cases where quick and easy encoding and decoding  of barcode is required such as retail stores and point of sales.

EAN 13 . Advantages and Limitations.


It is a very high density barcode and can encode large amount of information in smaller area.
The barcode is very easy to read and even a scanner, at an angle as acute as 45 degrees to the surface of the barcode, can easily decode the information
Wide use of the scanner in Europe makes it very portable and no advanced scanning devices are required to decode the information
Much suited to fast moving items on automatic machines.
Checksum digit provided self-checking mechanism.


Can encode only numeric data, not alphabets and special characters.
Like other linear barcodes, it has very small tolerance for damage and distortion and cannot be scanned in that case.

Ean 13. History and Purpose

EAN 13

EAN-13 is a linear barcode type most commonly used outside America, particularly in European countries. EAN-13 is an abbreviation for European Article Number which is now called International Article Number. EAN-13 contains 13 consecutive and fixed digits in total. The first 2, 3 digits of the EAN-13 code represent the country code next 9, 10 digits represent the manufacturer code and the product code while the last digits are the checksum digits. The total 13 digits of the EAN-13 barcode are divided into two equal parts of 12 digits by a guard bar in the center.


International Article Numbering Association has designed this EAN-13 barcode type and most of the European countries are using this barcode type. GSI is an international organization for standards. This organization defined the standard for EAN13; however, this type is not used in USA. Initially it was developed as Universal Product Code (UPC) with twelve digits in USA but later on it evolved to 13 characters, 12 digits and 1 checksum for self-checking.


Purpose of EAN-13 was to develop a bar code which can be easily and quickly encoded and decoded. It is for this reason only numeric data can be encoded with EAN-13. This numeric-only encoding scheme fits the bill and EAN-13 can be encoded/ decoded quickly, easily and acute angles.

QR Code. Usage


Used for document management, tracking products and time, inventory management, item identification and marketing purposes.

Widely used in automotive companies in Japan.

Business cards often contain QR codes inscribed on them which may contain related information to the websites or the links to the resume of a person.

QR code enabled scavenger hunt was introduced by Starbucks for promotion purposes which contained information regarding the hints encoded in the QR code.

Darling National Wildlife Refuge in Florida (USA) uses QR codes in trails which contain links to the detailed information regarding the animals.

Funny Fact: In Seattle, QR codes are inscribed on graves which contain link to the detailed information about the deceased person.

QR Code. Advantages and Limitations.

read the first part here


Can be scanned using a smartphone or any other phone with scanning capability.
QR codes are versatile, the can encode almost all types of data e.g. numeric, alphabets, special and binary.
Extremely fast scanning.
Like other 2-d barcodes, QR code has good fault tolerance. Even if some part of the code is damaged, information can still be decoded from the code.
Stores large amount of information unlike 1-d barcodes.


Smart phones used to scan QR codes are often expensive in comparison with simpler phones.
Relatively new barcode type, people are not much familiar with its use. Requires training in order to fully understand the concept.
Not very aesthetic, it contains random patterns of square boxes which might not look pleasing on products unlike 1-d barcodes.
