Barcodes are a symbolic representation of identification information.
We are all familiar with the contrasting light and dark bars found on
virtually everything we buy. In most cases the barcode represents a
number as in the UPC code use at retail. It can however be used to
represent most of the characters available on a keyboard.
There are several different symbologies used to create barcode. The
most common being the UPC code. There are other codes used throughout
the supply chain and in other countries. If one were to walk through
a warehouse the different barcodes used to identify shipping
containers, cartons, and storage locations would be evident.
What is required to utilize barcodes
Barcode printer
Barcodes can be printed on just about any type of printer.
Conventional Inkjet and LaserJet printers are just to print barcodes
on reports and process control documents. Barcode printers are used
to print labels that are then applied during manufacturing,
distribution, and retail processes. These specialized printers are
designed to print on label stock rather than paper. The labels have
an adhesive backing.
Barcode reader
There are several different technologies used to read a barcode. The
most common being the laser scanner used in retail stores. The
scanner can be a stationary device or can be handheld. Regardless of
the technology or style all the scanner does is decipher the barcode
and then pass the information on to the computer.

Software to control the printer & reader
Some type of computer software is required to control the barcode
printer and reader. In many cases a “work station” type system is
used to manage the barcode information. In this scenario the existing
computer systems are changed. The self-contained barcode workstation
is used to process the information as it enters and exits the
companies existing systems. In this way barcodes can be utilized
without changing existing systems.
Knowledge to utilize the technology
As with
any tool the skill/knowledge required to utilize it must be acquired.
This challenge usually falls on the company’s IT department. When
there is no IT department or the resources are just not available the
implementation support can be outsourced. Barcode projects are
neither complicated nor time consuming.
How can barcodes be utilized
Product –
By attaching barcode labels to products (in all case configurations)
it becomes easy to track inventory performance. Since barcodes make
it easier and more accurate for workers to record their inventory
movement actions inventory numbers take on a higher confidence level.
Locations –
Applying barcode labels to storage and process locations reduces lost
inventory, enables FIFO product rotation, and increases worker
productivity by reducing the amount of time spent searching for lost
inventory.
Documents –
When barcodes are added to process control documents (receiving,
shipping, manufacturing, etc.) work-in-process is more accurately
recorded and customer service can better inform customers and
suppliers as to order status.
Barcode utilization impacts the
bottom-line
·
increasing worker
productivity
·
Reducing inventory levels
·
Providing accurate process
status information (WIP, order status, etc.)
·
Compliance with customer
requirements
