About Near Field Communication
Near Field Communication (NFC) is a very short-range radio technology and is used for contactless communication between NFC-enabled devices and tags or cards. It has a range of typically no more than 4 cm, operates at 13.56 MHz, and supports transfer speeds of 106 Kbps, 212 Kbps and 424 Kbps. NFC provides an easy means of communication as it allows devices to interact with each other merely by being sufficiently close to one another.
NFC has many real-world applications, such as:
- Smart posters: Smart posters are posters that are embedded with small electronic tags that store data such as URLs. An NFC-enabled device can read smart posters and act on the data.
- Data exchange: NFC-enabled smartphones can exchange data such as electronic business cards simply by being tapped.
- Contactless payment: NFC-enabled smartphones can be used as credit cards.
- Ticketing: NFC-enabled devices can be used to gain access to events, transit systems, etc.
NFC is a standard-based technology defined by the NFC Forum. A number of ISO standards are used in the NFC architecture, most notably the ISO 14443 and ISO 7816 specifications. NFC technical specifications are well-documented and available on the NFC Forum.
