Uses Of Barcode and RFID Technology

A barcode is a visual pattern in which information is encoded that only a machine could read. It is a combination of black and white bars, all of which represents text characters which has an algorithm for every barcode type. The information encoded is read by a barcode scanner which converts the bars in to text which a computer can understand.

Usually barcodes holds the information of the product and with that information price is not fixed as the price is dependent on the POS (point of sale) software any company has or the database in a computer contains the price of that product.


There are two main types of barcodes

1.       One Dimensional (1D) Barcode:

One dimensional barcode looks like a “fence” and is also called UPC(Universal Product Code). The 1D barcode uses number from 0-9 for every pattern drawn. We all are also much more familiar to it as we find it on almost all of the things we use. Many types of One dimensional barcodes can be made, some of them contains numbers only while some contains any characters in them. Whenever the information is stored in 1D barcodes it is stored horizontally, information in it these barcodes can be read by any type of barcode scanner. It contains 20-25 characters.

2.       Two Dimensional (2D) Barcodes:

Two dimensional barcodes are complex in nature than the 1D barcodes as they store information horizontally and vertically, which helps it to store more information than the 1D barcodes while using less space . To be read properly it requires an imagescanner . 2D barcodes can contain upto 2,000 characters. It can hold quantity,size, web address or picture while 1D barcode cannot.

Barcodes can be in a variety of sizes and it can get as small as 0.125 inch square however, this small barcode will consist of limited amount of characters. The smaller the barcode is the harder it is for the scanner to read. And a very high resolution printer is required to print such barcode.
Barcode technology is very common these days  butthe users don’t value its importance.  On the other hand this technology never stops benefitting its users.

The technology is so simple that it only requires some printing equipments and a scanner to read that barcode. It benefits in a way that it improves the accuracy, speed and efficiency without imposing  higher costs.

How it is implemented around the globe: 


UPC barcodes are so successful that nearly every grocery store has been using this technology to keep a track of inventory. Because of UPC barcodes the cases of stealing the merchandise have reduced.


The barcode technology has been in use in hospital settings also. This is used for identification of the patient including his data, medical history,drug allergies etc.


Some 2D barcodes have a hyperlink to a web page. Special cellphones may read those patterns to browse  the website. It helps the shoppers to find the best price of an item within that locality.


Barcodes are also used to keep a track of rental cars, airline luggage, nuclear waste, registered mail, express mail and parcels. Barcoded tickets allow the holders to enter into different places like cinemas,theatres, transportation. It also facilitates proprietors to identify duplicate and fraudulent tickets.


  • ·          In point of sale management  barcode systems can provide up-to-date information on a business.
  • ·         The items that are sold frequently can be identified and reordered automatically.
  • ·         The items that are not sold frequently can be identified thus saves  from inventory build-up.
  • ·         The barcodes  provide the opportunity  of profiling consumers.
  • ·         Barcodes have proved useful in logistics and supply chain management also.
  • ·         When a delivery is packed for shipment, manufacturer gives a unique identifying number  to it.
  • ·         The database gets linked with the relevant information of that delivery (includes order               number,itemspacked,quantitypacked,destinationetc)
  • ·         The information is transferred by  Electronic Data Interchange and hence the retailer gets  to know about the delivery before it reaches its destination.
  • ·         Shipments get tracked before reaching their final destinations through UID and the store           gets to know about the shipment’s source, contents and costs.


(Radio frequency identification is the wireless use of electromagnetic comic to dealing information for the purposes of automatically identifying and following tag)

1.  Access management
2.  Tracking of artifact
3.  Tracking of  persons and animals
4.  Toll aggregation and contact less mercantilism
5.  Machine readable journeyn documents
6.  Stardust {for massively separated sensor networks}
7.  Tracking sports memorabilia to declare authenticity
8.  Airport baggage following logistics
9.  Timing sportsman like events


A Radio Frequency Finding system has three parts:

A tag
A transponder
The scanning aerial puts out radio frequency signals in a relatively improvident compass. The RF radioactivity does two things:

It provides a means of communicating with the transponder (the RFID tag) AND

It provides the RFID tag with the liveliness to pass (in the happening of inactive RFID tags).

This is an dead key split of the discipline ; RFID tags do not beggary to include batteries , and can hence stay serviceable for very longish periods of instant

The scanning antennas can be permanently pasted to a surface; handheld antennas are also usable. They can swear some mould you requisite; for admonition, you could shape them into a door plan to swallow information from persons or objects extremely through.

When an RFID tag passes through the tract of the scanning sensitivity, it detects the activation signalize from the aerial. That "wakes up" the RFID semiconductor , and it transmits the information on its microchip to be picked up by the scanning tentacle.

In acquisition , the RFID tag may be of one of two types . Activistic RFID tags person their own nation publication; the asset of these tags is that the reader can be overmuch farther off and solace get the signalize . Regularise the several of these devices are collective to screw up to a 10 year invigoration move they change specific sprightliness spans. Voice RFID tags , nonetheless , do not expect batteries, and can be some smaller and possess a virtually oceanic time move.

RFID tags can be translate in a comprehensive variety of circumstances , where barcodes or additional optically record technologies are ineffective.


In manufacturing

In the current century more than half of the goods in circulation are fast-moving-goods (FMCGs). The production line/assembly line of such product needs to move with quick efficiency with accuracy of the total count. Keeping track of the total count of the large inventory results in a tedious job. This job might result in reduce of efficiency and increase costs by wasting valuable labor power and time.  By employing RIFD tags, the management can easily keep track of the inventory. RIFD technology does not require the tag to be in the line-of-sight in order to be scanned.
If compared to barcode scanning process, this is highly efficient and less costly and time consuming. Apart from that RIFD tags are capable of storing more information as compared to barcodes. This helps the manufacturer keep record of the maintenance of the product without much hassle
In a nutshell, implementing the RIFD technology would ultimately result in
·         Less wastage of valuable workforce
·         Less time-consuming process
·         Increase efficiency
·         Better chances of improvement in inventory management and planning

In Warehousing:

Implementation of RIFD technology in warehousing would prove to be highly beneficial as it would allow the inventory to be tracked at every location. Each cargo unit can be fitted with its own RIFD tag. When the units are moved to and from the warehouse, the scanning system can automatically keep in track of the inflow and outflow of inventory.
For warehousing of multiple products, RIFD helps the centralized system keep in track of the kind and number of inventories being kept in or moved out of the warehouse without going through the hassle of keeping a manual record. This significantly reduces the chances of human error and results in the accurate handling of the product.
In short, RIFD helps in warehousing in the following ways
·         Helps in locating the exact inventory in record time
·         Helps in warehouse management and planning
·         Keeps track of movement of all goods

In Shipping:

Keeping track of inventory moving overseas in real time is a difficult and time consuming job. OInce the inventory reaches the desired location, it takes a day or two to recount the entire set of unit received. By using RIFD technology, this task not only becomes easier but also less time consuming. The technology records the movement of goods though their RIFD tags and keeps the management updated in real time.
Basically it does the following things
·         Keeps track of cargo movement without any time delay
·         Improves efficiency while reducing chances of error

In Distribution:

RIFD also proves to be beneficial in distribution procedures. It will greatly improve the delivery system by increasing efficiency in accurate delivery of the product while doing the job in record time. The information present on those tags is enough for the distributors to function on.

In Retail:

Over the past few years, with the development of supply chain management, various firms have now realized that including RIFD in their systems is not an operational advantage only but a vital part of strategic planning. In the longer run, this technology proves to be better as it increases efficiency of the company in all stages of supply chain and reduces costs of management as well.
