An Overview on Near Field Communication (NFC) and Blockchain Technology

Modeling and Performance Analysis of OAM-NFC Systems

“…N EAR field communication (NFC), which is based on the near field magnetic induction [2] at a distance much less than a wavelength of the carrier, is a kind of simple and efficient short-range wireless communication [3], [4]. Devices with NFC can achieve contactless, point-to-point, and lowpower-consumption data transmission in a very short range [5].…”

Development of sensors and non-destructive techniques to determine the performance of coatings in construction

“…Near field communication (NFC) is an RFID compatible interface and protocol which was developed with the aims of simplifying the RFID system [135]. This allows communication wirelessly between devices at a distance of approximately 10 cm or less, making it one of the shortest range wireless communication protocols [131]. It uses RFID technology and hence communication is based on the principle of magnetic coupling and can involve passive or active tags.…”

“…The main advantages of NFC, over RFID, are that reading devices are relatively simple and are now commonplace in mobile phones unlike RFID readers which are more complex. Data sharing is also relatively simple via the protocol [131].…”

“…An NFC device is classed as active if, similar to the RFID system, it is capable of generating a radio frequency field. If this is not the case it is classed as passive and hence transfers data via the inductive coupling method [131]. Communication is active if achieved by two active devices and passive if one is passive and one active.…”

“…Figure 2.36. A basic description of the RFID system[131] RFID is similar to a barcode technology, in terms of the data transferred, but does not require line of sight. The reader has a microcontroller, signal generator and a signal receiver/detector and an antenna for each.…”
