Radio Frequency Identification is a device that is used to identify the objects based on the electrostatic waves or electromagnetic coupling in the Radio Frequency (RF) portion of the spectrum in order to track the objects on real time. The Radio waves are used to transfer the digital data onto the tag. The working of the RFID system is similar to that of barcodes that helps to capture the information of the objects. The SAP solution provides a better option to manage the products of the industry so that tracking of the objects can be made easily. The integration of this system helps the vendors to be benefited in managing the inventory of their organisation. The RFID tags placed near the surface of the objects helps to identify the details of the objects. The RFID tag is used to track the objects that are fixed and moving.
In Qatar the Doha is rich in industrial areas where the maintenance of organisation’s asset is an important task. The business like petroleum, oil & gas, petrochemicals, crude oil, fertilizers, etc use RFID system to track the objects in real time. The RFID tag works better than barcodes in the way that it need not to placed respective to the scanner. It can be used to analyze the temperature, location, and position etc of the object that is used to maintain the details on the warehouse. The RFID tag was initially used to identify the animals which were later adopted to track humans and objects.
HOW IT WORKS?
The RFID tag attached to the device helps to identify the objects using the radio frequency waves associated with it. The RFID consists of three main components as tag, reader and antenna. The chip is mounted on the antenna to track the objects. The unique identification number helps to analyze the objects correctly. The chip is used to read the data transmitted through the objects and then stores it on the tag. The radio waves then pass the information onto the tag which then stores the data in the digital format that is readable to the users. This stored information can be used for future purposes.
ACCESSORIES OF RFID
The tags in the RFID are used track and monitor the objects through the radio frequency waves that are used to read and write the data into the database. It can be used for data collection, processing and transmission of information based on the tracking.
The RFID antenna is integrated with the chip vary with strengths through which the area covered by it can be determined. Each strength fits into specific types of systems through which the antenna captures and sends the information onto the tag.
The RFID tag is used to capture and send the data to the tag through which the tracking of the objects can be efficiently handled. The radio waves are used to transfer the data onto the tag.
NOTABLE FEATURES OF RFID
The RFID tag is provided with a unique identification number that is fixed on the device. This unique number registered for tracking purpose avoids the duplication of information to be passed. The system stores the information based on this unique number.
The RFID system is used to capture the information at high speed so that the accessing and retrieval of the information can be made faster.
ACTIVE AND PASSIVE TAGS
The active and passive are the two types of tags that prevail in the RFID system. The passive tags are used to store the information on the database through battery. The embedded chip captures the information and sends it for processing in less expensive manner. The active tags are those which run the tracking purpose through the battery which lasts for long term. These tags are used to cover the objects over a distance of more than 100 meters.
The tags of the RFID have the ability to do multi tasking in the sense it can capture more objects simultaneously. This kind of process would be helpful to track variety of process considering various departments at a stretch saving the time.
The system has the ability to protect the data that is fed into the system. The accessibility priority can be set to read/write operations. The password based protection can be enabled to the system so that the information transformed into database can be maintained with high security.
The RFID tool is highly reliable to the security of the data and maintaining it on the web based database. The scalable application is easy to update the information and new features can be easily added.
The wireless technology if flexible to the changing business process as it is user-friendly to track and access the information. The solution would give better results upon the obligations of the customers with long life.
BENEFITS OF RFID TAG
The system is affordable for all range of organisations that wish to manage their products and assets. This system monitors all the process of the objects accurately so that the configurations can be managed effectively.
The RFID devices are reusable to wide range of business processes. The RFID tags are designed in such a way that it can work on harsh conditions. The tags are resistant towards high temperature, pressure, and changing weather conditions. Through this system the RFID have long term survival to track objects.
LINE OF SIGHT
The RFID tag does not require line of sight in the sense that it can be placed at a different angle rather than to be placed exactly straight to the scanner. The RFID tag captures/senses the objects if they are placed at diagonally opposite position to track that object.
AREAS IMPLEMENTED RFID
Some of the applications of the RFID system are,
- Banking kiosks.
- Trading vehicles.
- Fixed assets of organisation.
- Theme parks in replacement of tickets.
- Health care solutions.
- Racing like marathon.
- Acts as security guard.
- People and animal tracking etc.
