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.
