What is barcode?
 It is an automatic identification
technology of dark bars and white spaces.
Structured to contain a specific piece of
information.
Combination of barcode technology with
computer and application software
improves performance, productivity and
profitability

WHY USE BARCODES?
 As far back as the 1960s, barcodes were used in
industrial work environments. Some of the early
implementations of barcodes included the ability
identify rail,road,cars, etc……
 In the early 1970s, common barcodes started
appearing on grocery shelves. To automate the
process of identifying grocery items, UPC barcodes
were placed on products.
 Today, barcodes are just about everywhere and are
used for identification in almost all types of business

BARCODE TYPES
 The type of barcode to use for a particular
situation depends upon:
1. The use.
2. The data encoded in the barcode.
3. How the barcode will be printed

There are two types of barcodes:
1. Linear barcodes
2.2D Barcode

BARCODE SCANNER
Handheld, single line
Fixed mount, multi-line

ADVANTAGES
 REPRESENT UNIQUE IDENTITY OF A
PRODUCT
 ACCURACY OF DATA INPUT (ERROR
FREE)
 LABOUR SAVINGS BY AVOIDING
MANUAL SYSTEM
 MORE ACCURATE DESPATCH

 COST EFFICIENT
 REAL TIME DATA COLLECTION
 MEASUREMENT OF WORK IN PROGRESS
THROUGHOUT THE FACTORY
 RAPID ACCESS TO TOTAL PRODUCTION
COSTS

DISADVANTAGES
 System Failure may cost more delays.
 Scratched or crumpled barcodes may cause
problems.
 Data must be coded in the barcode.
 In laser scanning, durability and cost are the
two disadvantages.
