Near Field Communication
NFC is a short form for Near Field Communication, a technology that allows similar or NFC enabled devices to communicate with each other either by touching or bringing them into closer proximity – all wirelessly and is usually done within not more than a few centimeters •The communication can also be established between a NFC device with an unpowered NFC chip, which is called as tag. For example a movie poster outside a theater.
So in this case your Smartphone would be the initiator and that movie poster would be the passive objective. Once, you touch the Smartphone to this tag, the information related to the movie, such as trailer, cast & crew info, timings will be received to your NFC device. •Near Field Communication is a short-range high frequency wireless technology, which enables the exchange of data between devices over about a 10-centimeter distance.
The design includes a near-field transmitter and receiver to send data from one computer to another •NFC (Near Field Communication) is a new technology that’s being added to mobile phones that allows an NFC sensor chip to be recognized by simply tapping it with an NFC-enabled phone or holding the phone in close proximity to it, to automatically make a payment, download a coupon, or open a website, video, or other digital content.
Though not yet in widespread use because of the limited number of mobile devices designed with NFC sensors and the relative complexity and expense of producing materials with embedded chips, NFC is a growing technology platform that can be used to address a variety of scenarios. •Near Field Communication is a a short-range wireless technology that allows information to be exchanged between two NFC- enabled devices over short distances.
Handsets with built-in NFC will dramatically simplify the way consumer devices interact with one another. Near Field Communication (NFC), as an emerging and promising technology, is an integration of Radio Frequency Identification(RFID)technologywithmobiledevices. NFC-enabled mobile devices can act as contactless smart cards and are also capable to read and write data from/to those cards. Research endeavors concerning NFC appear to focus mainly on development of NFC enabled services and applications. On the other hand, benefits and underlying values associated with different NFC applications’ service is not yet well elaborated. NFC is a short-range, low-power communications protocol between two devices.
One device, the initiator, uses magnetic induction to create a radio-wave field that the target can detect and access, allowing small amounts of data to be transferred wirelessly over a relatively short distance (in NFC’s case, the distance must be less than 4 inches). If that sounds a lot like RFID, the tech used by, for example, wireless toll-collection devices like EZ-Pass and FasTrak, it’s probably because NFC is pretty much an evolved form of RFID.
The difference is that RFID is a one-way street: Your EZ-Pass transmitter beams your $4. 25 toll to the tollbooth’s receiver, and that’s the extent of the transaction. But, crucially, NFC is two-way, allowing your NFC-enabled gadget to both send and receive information. Advantages of NFC Technology •Inherent security •Ease of use (Very familiar to people, only touch) •Mobile phones can be used both as an information storage devices or an NFC reader •They can read information from NFC tags •They can be used as a digital storage e. g. storing credit card information.
