System Overview
The following sections describe how the Intelligent Library System Open Plus interacts
with a library’s circulation system to maintain its collection.
How RF Query Tags
The Intelligent Library components - Self-Checkout Station, Intelligent Sensor, Staff
Station Reader, and Portable Reader - all use a Radio Frequency (RF) antenna and
transceiver system (interrogator) which detects and reads the RFID tags. Communications
occur when an interrogator’s radio field is triggered by a tag passing through it. When
energized, the tag presents the programmed item-specific information to the interrogator
for further processing.

The data, routed by the Intelligent Library Controller, is compared to the Library
Management System (LMS) database, in order to identify the checkout status of an item.
How ILS Maintains the Library’s Collection Database
The Intelligent Library Controller is the communications gateway between the ILS
subsystems and the library’s Library Management System (LMS) so that the check-in,
self-checkout, inventory management, and security activities can all be accomplished.
All library materials including books, CD/DVD materials, videotapes, and cassettes are
tagged with a permanent RFID tag. This tag contains information that uniquely identifies
the item within the library circulation database. Patron cards identify patrons when the
card is scanned at the Self-Checkout Station. The card stores coded information unique to
the individual patron that identifies the user to the Library Management System. The
patron can then be validated as eligible or ineligible to use the library checkout privilege.
