!!! Overview
[{$pagename}] stands for [Near Field Communication] a standard defined by the [NFC Forum|http://nfc-forum.org/|target='_blank'], a global consortium of hardware, software, credit-card, banking, network-providers and others who are interested in the advancement and standardizing this technology.
[Near Field Communication], As the name implies, is a set of short-range wireless communication standards typically used in [Mobile Devices] and other electronic [devices].
[{$pagename}] operates on the frequency of 13.56 MHz with data transfer of up to 424 kilobits per second.
[{$pagename}] standards exist to ensure all forms of near field communication technology can interact with other NFC compatible devices and will work with newer devices in the future. Two major specifications exist for NFC technology:
* ISO/IEC 14443 - specifies the ID cards used to store information, such as that found in [{$pagename}] tags
* [ISO 18000-3] - an international standard for all devices communicating wirelessly at the 13.56MHz frequency using Type A or Type B cards which includes both [{$pagename}] and [RFID] communication.
[{$pagename}] and [RFID] (Radio Frequency Identification) are sometimes used interchangeably, but pagename is really an extension of [RFID]. [RFID] waves can have very long ranges as they are generally used in manufacturing, inventory and object tracking. In contrast, [{$pagename}] limits the range of communication to within 2 to 4 inches. This makes [{$pagename}] more suitable for secure applications like payments.
[{$pagename}] has three standard modes of operation:[1] [2]
* [reader/writer|ReadWrite] (R/W) mode - allowing for accessing external [{$pagename}] tags
* [Peer-to-peer] ([P2P]) mode - allowing for [data] exchange between two [{$pagename}] [devices]
* [Card-Emulation] (CE) mode - (also called [{$pagename}] target) which allows the [device] to act like a [credential].
[{$pagename}] allows you to share small payloads of data between an [{$pagename}] tag and an [{$pagename}] enabled devices or between two [{$pagename}] enabled devices.
!! [{$pagename}] vs [Bluetooth]
[{$pagename}] may sound more like [Bluetooth] because it is also a [communication] technology between two [Bluetooth] enabled devices over a short range. They are similar in that aspect, but they are also different in other aspects. For instance, [{$pagename}] does
* __NOT__ need a pairing process
* can read from passive [{$pagename}] tags
* consumes low power
* connects to its target very quickly ( one tenth of a second)
These qualities make [{$pagename}] a good candidate for [Mobile Payments]
