Advantages and Disadvantages of RFID technology



RFID has many advantages and one of the main ones being that it reduces the amount of time required to perform circulation operations. This allows for easier and faster check out time for patrons and staff. According to an article published by the University of Maryland some of the advantages are as follows:

"- Reduction of staff duties
- Reduction of staff injuries
- Reliablity
- Tag life and appearance"

RFID systems frees up staff to work on other duties because patrons are put in a position that they are able to check out their own materials using a self-check out system similar to what is found in grocery stories. It also reduces that amount of staff injuries in that it prevents that number of stress injuries from happening. Stress injuries results from having to flip materials over or hold them at a certain angle so that they barcode can be scanned. Tag life is long than previous systems. it is estimated that the tag life will last for about 10 years.

The disadvantages of the system according to the article are as follows:

"- Reduction of staff duties
- Cost
- Susceptibility of tags
- Big brother and invasion of patron privacy"

Reduction of staff duties fall into both categories because in some instances with the implementation of automation in libraries it may require a reduction in staff in library in some areas which is not always good. Another huge disadvantage is the one of privacy. Privacy invasion has been a popular topic of discussion in libraries. As librarians we are to protect the privacy of the patrons that we serve and with implementation of automation the question of whether patrons privacy still private has become a question. As this technology improves I'm sure that the issue of privacy will continue to be an issue until something is done to confirm the  protection of patrons' private information.

Three Types of Tags

The RFID system is headed off by what is called a tag. A tag is a programmable chip and an antenna. Many libraries are adopting the tag system instead of the old barcode system. According to an article found in the Library Philosophy and Practice Journal, "there are three types of tags: 'read-only', 'WORM' (Write once-read-many), and 'read/write'". Read only tags are not rewritable. WORM tags do not have the ability to rewrite them later. Most libraries however choose the read/write tags because information can be changed or added. Not only did this article highlight certain types of tags but there are also different tags associated with the different types of materials in the library.

Tags such as square tags, credit card tags and donut hub tags which are associated with
books, periodicals, CDs, and DVDs. See photo for more information concerning these tags.

Components of a RFID System

RFID can be very overwhelming for those who do not know a lot about it. This post will discuss the fundamental components that required in order for things to work properly. According to Patrick J. Sweeney in his article entitled, "Examining the Elements of a Basic RFID System" he lists that following as the four foundational components in a basic RFID system:

"- A transponder (more commonly just called a tag) that is programmed with information that uniquely identifies itself, thus the concept of 'automatic identification.'
- A transceiver (more commonly called a reader) to handle radio communication through the antennas and pass tag information to the outside world.
- An antenna attached to the reader to communicate with transponders.
- A reader interface layer, or middleware, which compresses thousands of tag signals into a single identification and also acts as a conduit between the RFID hardware elements to the client's application software systems, such as inventory, accounts receivable, shipping, logistics, and so on."

Each component play an important role in the success of the workings of this system. We explore them with the following blogs to better understand how the system works and to under stand the librarians role in all of this.
