This work focuses on the design and implementation of a fingerprint biometric identification system for charging and discharging library materials. Charging of library materials denotes lending or borrowing of library materials, however discharging is done when the patron or borrower return the borrowed library material. The crux of charging and discharging library materials is the means to identify the borrower and the book borrowed amidst great number of library patrons and huge collection in the library. Many methods of charging and discharging have been developed over the years. Most of these methods use a borrower's & book's card as means of identification, until the advent of the automated system. This work is aimed at using fingerprint identification as a veritable method for patron's identification during charging of library materials. It covers the conceptual analysis and practical design of a fingerprint identification system using Digitalpersona-SDK and is implemented for charging and discharging materials in the library. The fingerprint biometric identification system is designed using Java programming language and MySQL database at the backend for storing patrons' information including fingerprint images. Usability evaluation of the system revealed that the fingerprint approach to charging and discharging of library materials is faster, more effective and efficient than the manual system.
