Each physical library thing - book, tape, CD, DVD, and so on could have its own thing number. To help it, the things might be barcoded. The reason for barcoding is to give a one of a kind and readable identifier that interfaces the barcoded physical thing to the electronic record in the list. Standardized tag must be genuinely joined to the thing, and scanner tag number is gone into the comparing field in the electronic thing record.

Standardized identifications on library things could be supplanted by RFID labels. The RFID tag can contain thing's identifier, title, material sort, and so on It is perused by a RFID peruser, without the need to open a book spread or CD/DVD case to check it with scanner tag peruser.
