What is the difference between NFC & RFID?

NFC (Near Field Communication) in Chinese is called near field communication technology. NFC is developed on the basis of non-contact radio frequency identification (RFID) technology combined with wireless interconnection technology. Technology started much later than RFID, around 2003, a short-distance wireless communication technology mainly promoted by Philips, Nokia and Sony. It is a short-distance non-contact communication method with a working frequency of 13.56MHz. , the communication rate is 106kbit/sec to 848kbit/sec. With the mobile phone as the carrier, the non-contact IC card application is combined with the mobile phone, and the card, reader, and point-to-point three application modes are used to realize mobile payment, industry application, point exchange, electronic ticketing, identification, anti-counterfeiting, advertising, etc. Applied service offerings.RFID (Radio Frequency Identification) is a wireless communication technology that uses radio waves to transmit data to realize long-distance identification and tracking management of objects, animals or people. RFID technology consists of tags, readers and middleware, among which tags are the core components of RFID. The tag has a built-in chip and an antenna, which can store and transmit data, and has a unique identifier that is not repeated. The reader/writer sends radio waves to the tag, reads the data in it, and transmits it to the computer system for processing. RFID technology is widely used, including logistics management, warehouse management, production line automation, vehicle management, library management, animal tracking, personnel access management and other fields. Due to its advantages of high efficiency, precision and automation, it has attracted more and more attention and application from enterprises and institutions.NFC and RFID look similar at the physical level, but they are actually two completely different fields, because RFID is essentially an identification technology, while NFC is a communication technology.

The difference between NFC and RFIDWorking frequency: NFC frequency is fixed at 13.56MHz, while RFID includes active (2.4G, 5.8G), semi-active (125K, 13.56M, 915M, 2.4G, 5.8G), and passive RFID, among which the common Source RFID can be divided into low (125KHz/134.2KHz), high frequency (13.56MHz) and ultra high frequency (860-960) frequency bands according to frequency.Working mode: NFC integrates point-to-point communication function, reader function and contactless card function into one chip, while RFID consists of two parts: reader and tag. NFC technology can both read and write, while RFID can only read and judge information.Transmission distance: The transmission distance of NFC is much smaller than that of RFID. The transmission distance of NFC is only 10 centimeters, and the transmission distance of RFID can reach several meters or even tens of meters. NFC is a short-distance private communication method. Compared with RFID, NFC has the characteristics of short distance, high bandwidth, low energy consumption, and high security.

Application fields: NFC is more used in the field of consumer electronics, and plays a huge role in access control, public transportation, mobile payment and other fields; RFID is better at long-distance identification, and is more used in production, logistics, and tracking , Asset management.ANy question,please feel free to contact SLON.
