Radio Frequency Identification (RFID, for short) is a technology used for tracking and identification of objects in many areas of commerce, shipping, manufacturing, and, beginning in the late 1990's, in the circulation and inventory processes of libraries, and is useful for security applications, as well.

RFID is similar to barcode technology in that it employs coded labels to communicate information about a specific item (a library book or DVD, for instance) to a central server. However, since RFID uses radio frequencies to communicate with items' attendant labels rather than scanning barcodes with a laser, the RFID reader does not require a direct line of sight to the label to read it, can read multiple items at once, and can read through physical tissue such as a book cover or DVD case.

Circulation Advantages of RFID

Checkout

RFID technology's ability to read ID tags regardless of position or orientation as well as detect signals through physical materials is particularly advantageous for library circulation processes. Since several items can be read at once, checkout procedures can be accomplished much more rapidly than with barcode technology, which requires that each item be handled individually. For these same reasons, patrons can accomplish self-checkout much more efficiently, as well.

Implementation of RFID in libraries generally leads to greatly-reduced queues at the checkout counter, enhanced customer service, and less repetitive strain injuries for library staff [1]. A study commissioned by the San Francisco Public Library anticipated a substantial reduction in risky, repetitive motions associated with circulation such as lifting, reaching and grasping as a result of its RFID implementation [2].

Checkin

RFID can be equally advantageous for checkin processes, as well. In addition to being able to check in multiple items simultaneously, RFID readers can be affixed to book return slots, effectively checking in items as they pass through the slot. RFID can further streamline checkin when used in conjunction with an automated materials handling (AMH) system. A conveyor carries items past an RFID reader, which checks them in and then sorts them by category into bins or onto carts, eliminating the need for staff to handle items until the fine-sorting step of the process.

The time saving potential of an RFID implementation can be substantial; an Australian library reported an 80% reduction in time spent on circulation procedures by staff after RFID was implemented [3].

Inventory

RFID also has had a significant impact on inventory processes in libraries. With a fully-tagged collection, inventory can be taken with a portable, hand-held wand which is passed alongside the books on the shelves; the reader picks up the individual signals from each item's tag, without needing to remove or even tip the books outward from the shelves. As a result, says Karen Coyle, with RFID "not only does the cost of doing an inventory in the library go down, the odds of actually completing regular inventories goes up" [4].
