Abstract
Radio-frequency identification (RFID) is a small electronic device that utilizes the radio waves for the purpose of security, personnel identification, surveillance, medical identification, patient history, library automation, baggage application, toll collection, file tracking, electronic payment, etc. Three types of RFID tags namely, active, passive, and semi-passive RFID tags, are currently available. The basic components of RFID system are RFID transponder, antenna, and transceiver. This review mainly focuses on the various applications of RFIDs in the pharmaceutical sector. RFID has potential applicability in pharmaceutical and healthcare sectors such as product tracking and inventory control, limiting the Bullwhip effect, supply chain management, maintenance of dyes and punches, preclinical study, identification of patients and hospital staff, avoidance of medication errors, etc., which have been discussed in detail. Besides having innumerable applications, RFID technology is in its early stages in pharmaceutical systems and hence its potential is required to be explored more in practical. The RFID systems are expensive which makes the adaptability of this system very difficult. Hence the development of low cost RFIDs is a big challenge at present and more research activities are required in this direction.
