This research paper is to review the techniques available in asset tagging or labelling such as barcode, RFID, and QR Code. It is known that QR codes are mostly used for marketing and promotion, information dissemination, and localization. By taking advantage of the increasing use of smartphones and their ability to read QR codes, the researchers attempted to implement QR codes on the existing system for improvement where it could facilitate users in borrowing or reserving library materials. The current web-based system allows users to borrow books however book reservation is only possible for physical materials available in the library repository. With the implementation of the QR code, this flaw can be solved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
