RFID disadvantages

The RFID technology seems to be the next generation technology, but with its expensive installation cost, it is hard to adopt for small and medium enterprises. For additional information on RFID costs, visit this website: http://www.rfidjournal.com/faq/20

Another disadvantage that RFID has is the interference of other radio waves such as a presense of mobile phone towers. Although RFID uses radio waves and can track a product anywhere, it is also possible that other radio waves such as cellphones can interrupt these radio waves, which might lead to unattainable information or false information. Furthermore, each country may have their own sets of range in frequencies that allow RFID tags to function. This will make international shipping companies and other companies to follow each countries rules and laws, which may become very time consuming. Lastly, RFID can be used as an invasive technology. Customer's identity or privacy information can be tracked if stores or a facility does not deactivate the RFID tags in a product after purchased. If left alone, by simply holding the product, any RFID reader can process the information inside the RFID tag, which may be harmful to the person. Even if the RFID is costly to install and can be used to steal people's information, it can be a great asset if this techology is used properly.
