Near Field Communication is a standard technology that enables data to be exchanged between two chips, in this case, one contained in the mobile phone and the other in the connected product.
Unlike Bluetooth, NFC enables a connection to be established with a compatible device extremely rapidly. Indeed, the startup, scanning, pairing and authorization procedures take a significant amount of time in Bluetooth. This slow speed may be considered as a sticking point for its wide-scale use among the general public.
NFC is by definition a technology based on proximity, since actions are only possible when the terminal is placed within a few centimeters of the target. This technical constraint involves a voluntary process by the user, making inadvertent activation virtually impossible. It’s worth noting thatBluetoothconnections can operate at a range of between 1 and 10 meters.
On the basis of your location (mainly shopping centers), this sends you personal notifications about products situated nearby thanks to beacons. To complement NFC, which works at very close range permitting a closer relationship with the product (its composition, its authenticity, etc.) as well as payment, the role of iBEACON would be rather to attract consumers into shops and increase their basket value.
The bottom line is :
RFID is a generic term to describe a technology for transmitting an identity (ID: often a serial number) via RF ( Radio Frequency). An RFID device involves three main components:
