Whatever you read on latest Object Identification Technology in market you will come to know about Radio Frequency Identification (RFID) Technology. Surprising fact is that it is not a new technology; it was first used over sixty years ago by Britain to identify friend and foe aircraft in World War II and was part of refinement of Radar.

RFID is evolving as a major technology enabler for identifying and tracking objects (such as Goods, Asset, Persons, Animals). It helps organizations in locating critical objects more quickly to improve process efficiency and accuracy and also promises to enable new efficiencies in the supply chain by tracking goods from the point of manufacture through to the retail point of sale.

How RFID guided Solutions works?

RFID guided solutions are reading of physical RF Tags on single products, cases, pallets or reusable containers which emit radio signals to be picked up by reader devices. These devices and software supported by sophisticated solution architecture enables the collection and distribution of location based information on real time basis.

RF Tags contain a unique identification number and additional necessary information related to objects for organizations that needs to track the physical location of objects. All Information stored on RFID tags accompanies items as they travel through supply chain or organizational business processes. All information on RFID tags, such as product attributes, physical dimensions, prices or laundering requirements, can be scanned wirelessly by a reader at high speed and from a distance of several meters.

Complete Solution combines technology of RF Tags and Readers with Database ensures real time access to up to date information about relevant products/objects at any point of time in supply chain/organizations.

Listed below are core benefits of using RFID technology in state of the art solutions.

No line of sight needed.
Allows check-out and check-in several items simultaneously.
Information directly attached to product.
Performing both identification and antitheft in one single operation.
Different shape and sizes available.
Able to tag almost anything.
Accelerate scanning and identifying.

RFID tags are rugged and robust and can work in harsh temperatures and environments.
RFID Tags are Customizable according to the application / usage
RFID tags in Most applications can be detected ”hands off”
RFID tags can be placed inside the packaging or even in the product itself
Direct physical contact between the tags and the reader is not required.
Multiple RFID tags can be read at the same time.
Customizable Solutions, Integration with other System also possible
RFID technology is better than bar codes as it cannot be easily replicated
RFID Enabled solution increases the security of the product
RFID systems play a key role by managing updates of stocks, transportation and logistics of the product, in product supply chain
The RFID system works at a remarkably high speed, even in adverse conditions
RFID Systems are able to reduce the need of Human intervention and provides process automation

Problems with RFID Technology

Liquid media and Metallic Surface

It is difficult for an RFID reader to read the information in case of RFID tags installed in liquids and products having metal surface.
Problem is that the liquid and metal surfaces tend to reflect the radio waves, which makes the tags unreadable.

Communication Media for on field Devices

Interference becomes necessary if devices such as forklifts and walkie-talkies are in the vicinity of the distribution centers.
The presence of mobile phone towers has been found to interfere with RFID radio waves. Wal-Mart, the retail sector giant, has installed billions of RFID tags in their products throughout the world and they have encountered such problems.

Necessary to follow Global Standards

The USA and Europe, for instance, have different range of frequencies that allow RFID tags to function. This makes it mandatory for international shipping companies and other organizations to be aware of the working pattern of other nations also, which can be very time-consuming.

Privacy Concerns

RFID technology has been referred to as invasive technology. Consumers are apprehensive about their privacy when they purchase products with RFID tags.
Once the radio chips are installed in the product, the customer can be tracked by the RFID reader. However, many stores have a facility that deactivates the RFID tags after the product has been purchased.

Future of RFID Technology

RFID is said by many in the industry to be the frontrunner technology for automatic identification and data collection. The biggest, as of yet unproven, benefit would ultimately be in the consumer goods supply chain where an RFID tag attached to a consumer product could be tracked from manufacturing to the retail store right to the consumer's home.

Many see RFID as a technology in its infancy with an untapped potential. While we may talk of its existence and the amazing ways in which this technology can be put to use, until there are more standards set within the industry and the cost of RFID technology comes down we won't see RFID systems reaching near their full potential anytime soon.

An antenna or coil.
A transceiver (with decoder)
A transponder (RF tag) electronically programmed with unique information
The antenna emits radio signals to activate the tag and to read and write data to it.
The reader emits radio waves in ranges of anywhere from one inch to 100 feet or more, depending upon its power output and the radio frequency used. When an RFID tag passes through the electromagnetic zone, it detects the reader's activation signal.
The reader decodes the data encoded in the tag's integrated circuit (silicon chip) and the data is passed to the host computer for processing.

RFID Tags

Passive Tags

The tag functions without a battery; these tags have a useful life of twenty years or more. The tag is typically much less expensive to manufacture.The tag is much smaller (some tags are the size of a grain of rice). These tags have almost unlimited applications in consumer goods and other areas.

Semi-Passive Tags:

On-board battery, but cannot initiate communication. Can serve as sensors, collect information from environment: for example, 'smart dust' for military applications. More expensive, longer range

Active Tags:

It can be read at distances of one hundred feet or more, greatly improving the utility of the device. It may have other sensors that can use electricity for power. On-board battery, can initiate communication.

RFID Readers

RFID Handheld Reader:

Handheld Reader can be used to manage the inventory and trace the lost / missing inventory item. RFID handheld reader will be able to search by reading the RFID tag pasted on the different objects.

Fixed (Stationary) RFID Readers:

Stationary RFID readers can be affixed to walls, doorways, other types of portals, and tables/desktops. As tagged items pass through the portal (or by the table or desk), the reader picks up the tags' data, which are then stored in a database. The database is updated in real-time, making RFID a powerful technology for use in asset tracking and inventory management applications. It is suitable to use at the dock door of warehouse.

Mounted RFID Readers:

Mounted readers differ from fixed readers in the way that they are typically attached to moving objects, such as trucks or forklifts, and they keeps track of the movement of items from one location to another. Mounted RFID readers read the tags attached to the items, cases, or pallets that the vehicle is carrying and immediately send their data to the database host. Mounted readers can operate in either autonomous mode or interactive mode.
