Discussion
Radio Frequency Identification is used in library for :
(i) Circulation of Documents
(ii) Cataloguing of Documents
(iii) Security of Documents
(iv) Acquisition of Documents
Answer: D
Radio Frequency Identification uses tags put in books, and readers at the counter and the gate, so it speeds up circulation, the issue and return of documents, and provides security, since the gate gives an alarm if an item that has not been issued leaves the library. It is not a method of cataloguing or of acquisition, which are done by other means. So (i) and (iii) are correct, option (D), and the options that carry (ii) or (iv) are wrong.
