PROS AND CONS OF RFID TECHNOLOGY

RFID is such a technology built to trace virtually several numbers of points with the help of an electronic tag that saves data and conveys the processed data to its users. A set up of this nature using this kind of technology is referred to RFID. These systems have a source of energy on board and do not broadcast signals to its readers periodically. RFID is known to be an automatic identification system. This system just like magnetic stripe or a barcode of a debit card, this technology tag has a unique identity code which could be read with the help of a scanner. RFID when compared with other identification technologies, it makes use of radio waves for communication. The moment its reader captures its waves, it automatically changes them into a digital like data which recognizes the object that contains the tag.

ADVANTAGES OF RFID TECHNOLOGY


Scanning Range: RFID technology has the ability to scan a tag provided it’s not out of the frequency range. It does not in any way by default have line of sight drawback. Other identification systems like barcodes for instance, the user needs to be close to the bar code before scanning could take place. RFID technologies possess strength here in that it automatically feels tag ID from a distance, and in addition to that it takes tag ID across the barriers between the reader and the label. This is very interesting.


RFID Capabilities: This system is so spectacular in the sense that multiple items could be scanned simultaneously. Take for example, scanning all your incoming goods to the warehouse, it simply allows you to verify all items at once taking he pain of having to run individual items away. This can be a pain in the neck but with the help of RFID, this pain is eliminated.Convenience and speed: RFID technology users can work in less time as it scan tags within a twinkle of an eye and runs on automation. Other scanning technology may need manual mode of operation and work with more time since the user has to adjust the drive and code for successful scan to take place. RFID enjoys speed of operation in services like the cashless payments.


For instance, some theme park or venues gives visitors to charge cash on RFID engraves items so they can operate a reader to pay. The need to move about with wallet and spending more time online is eliminated. Other advantages of RFID technology is its contribution to the provision of worthy services to clients via innovative ways businesses have been able to track store items. A handful of companies have to a large extent benefitted from the innovation this technology offers spanning from retail stores, local consulting firms, even the manufacturers of the technology are not left out in the chain of beneficiaries. -


- Another awesome advantage this technology possesses is competitive advantage gained by retailers and related stores who have overwhelming demand supply by utilising RFID in their supply chain. The increase in efficiency that follows the one time investment and implementation of same by establishments will ensure rapid pay-back period for the investment. -


- It is on record that Wal-Mart happens to be the pace setter in the retail chain for the utilisation of RFID across their business network. Once Wal-Mart recorded a successful history with the device, this saw other companies emulating Wal-Mart.


Intermec also recorded landmark progress with the RFID system a decade ago with strong and recyclable RFID tags which could be written several time.This technology can manage harmful chemical exposed to it and resist temperature range of minus 50 degrees Fahrenheit to 250 degree Fahrenheit.


The RFID industry witnessed prosperity and resonance that other companies in this field got themselves in this line of business by making its part and components. In a way, it’s a multiplier effect within the industry.

DISADVANTAGES

RFID cost: As a matter of fact, RFID system usage dates back to the '70s, its huge up-front cost puts a barrier to its usage by companies who need them. However, the cost are beginning to drop, the technology is still way too expensive to install and put to use compared to its alternative like the optical scanner. Companies who never bother about the cost, its serves as a means to reduce labour cost for them and increase their working efficiency.

Question of analysis: RFID system can be reliable; however, they may still develop problems. This is not to say that their readers won't walk through some non-metallic items, the thing is they have issues with water and metal. How effective they are at scanning multiple objects, they also present possible problems which could result to malfunction. If its user captures from several tags simultaneously, collision tag could occur. In a nutshell, reader collision could be an issue if two drives overlap each other.

Security and Privacy: This technology poses some security issues for its users. For instance, any device without official authorization could read or go further to even edit the data found on the labels without prior knowledge of the user to whom the object belongs. so what this showcases is that lateral channel attack could take data from RFID by simply changing from a tag to a drive, this could consequently give attacker access to information they need to feed on or needs to be fixed.

CONCLUSION

As nothing in life is certain, the future of the RFID can't be predicted with precision, nonetheless the system has come to stay. Majority of its users have one problem or the other to surmount in their bid to ensure the technology is practically implemented. The issue of privacy concerns will linger, however the total cost of the technology will be affordable to many over time. To ensure the success of RFID, there is the need for stakeholders to work with privacy counsels to come up with an acceptable procedure to practice RFID without antagonizing customers. Innovations keep cropping in everyday in the sphere of technology, so it is expected that technology will never stop to develop for RFID and host of other applications would be discovered.
