Radio Frequency Identification

Radio-Frequency Identification system (RFID) is a set of communication protocols to identify objects, record metadata or control individual target through radio waves. It is a method of transmitting data via radio waves in magnetic fields wirelessly and without contact. Connecting RFID reader to the terminal of Internet, the readers can identify, track and monitor the objects attached with tags globally, automatically, and in real time, if required. Generally, RFID or identification system by using radio frequency, is a wireless identification system that is able to exchange data by establishing information between a tag that is connected to an object and a reader.

Near-Field Communication (NFC) is a short-range, standards-based wireless connectivity technology, that uses magnetic field induction to enable communication between electronic devices in close proximity. Based on RFID technology, NFC provides a medium for the identification protocols that validate secure data transfer. NFC enables users to perform intuitive, safe (?), contactless transactions, access digital content and connect electronic devices simply by touching or bringing devices into close proximity. It is being widely used nowadays in contactless payment systems, similar to those used in credit cards (PayPass, PayWave, EMV) and electronic ticket smartcards and allow mobile payment to replace or supplement these systems.
