What is a Barcode?A barcode is basically a series of parallel alternating black and white patterns that represents a sequence of numbers or characters. It allows real-time data to be collected accurately and quickly.
The combination of barcode with appropriate hardware and application software creates the potential for improving performance and productivity.
In it's early days, barcode technological development is driven by retail applications. However, industrial applications soon followed.
The first major success of barcode is the UPC (Universal Product Code) barcode that is used in the US and Canadian supermarkets. Subsequently, this led to the adoption by European countries and the creation of the EAN (European Article Numbering) code and symbol in 1976.
I need to print barcodes, what do I need to do?You can easily print the barcode labels yourself with a laser printer. Alternatively, you can have your labels printed by commercial printing firms.
To print the barcodes yourself, you can either purchase a barcode software or barcode fonts.
How do I make sure my barcode is scannable?Barcode scanners work by analyzing and interpreting the alternating black and white bars. It is important to leave adequate white space before and after the actual barcode.
The size of the barcode also matters. The bigger the barcode the easier it is to scan.
Barcode FontA font is an organized collection of text characters. A font in general defines the shape, size, pitch and spacing of text characters.
A Barcode Font is a specially designed font that allows you to specify and generate barcodes on normal text characters. It is extremely easy to use. You can just install the font, then load up your text editor like Wordpad or Word to create the barcodes. Most computer applications today that support text enable you to choose from among many fonts.
Code 39 BarcodeCode 39 barcode is one of the earliest and most widely used barcode. It is a variable length barcode, which means that you will be able to encode any number of characters as a barcode. It supports alphanumeric characters and is used in a wide variety of applications.
Code 128 BarcodeCode 128 is one of the most popular modern barcodes. It is a very high density barcode supporting alphanumeric characters. This barcode is used as the basis for many other barcodes like UCC/EAN, HIBC(Health Industry Barcode) and the Blood Bank Industry barcode.

UCC/EAN BarcodeUCC/EAN is an international barcode format used widely by many different companies. It uses a list of Application Identifiers (AI) for identifying the structure and format of the data in the barcode. For example, AI 00 is used for identifying a 18 digits Serial Shipping Container Code.
I2of5 BarcodeI2of5 (Interleaved 2 of 5) is a widely used, high density barcode supporting numeric characters. The data to be encoded must contain even number of digits as each two digit numbers is uniquely represented by a set of bars and spaces in the barcode. The character '0' may be added to the beginning, if the data does not contain an even number of digits.
ITF14 BarcodeThe ITF14 is a 14 digits barcode used to mark the external containers of products with a EAN identifier. It is based on the I2of5 barcode. ITF14 barcodes usually contain a top and bottom bar (sometimes rectangle) called the Bearers bar. The purpose of the Bearers bar is to make sure that the barcode is read completely.
UPCA Barcode12 digits Universal Product Code. This barcode is used to identify each product with a unique code. It consists of a 1 digit Numbering System, 5 digits Manufacturer's code, 5 digits Product Code and 1 Check Digit.
