NFC MOBILEPHONES

NFC MOBILEPHONES
NFC is a wireless technology that makes use of interacting electromagnetic radio
fields to transmit small bits of information between an "initiator" and a "target" -- a key card and your hotel room door, for example. It's similar to Bluetooth in the sense that both are short-range communication technologies, and is considered a subset of existing RFID (Radio Frequency ID) standards given that is uses radio waves for identification purposes. But NFC has its unique set of characteristics that will determine how it's used in real-world practical applications
How Does It Work?
NFC involves an initiator and a target, where the initiator actively generates an RF field that can power a passive target without an electricity source. This enables NFC targets to take very simple form factors such as tags, stickers, key fobs, or cards that do not require batteries.
What Will We Use It For?
Much noise has been focused on NFC's ability to power mobile payments and that's perhaps because the promise is enticing: It will turn your mobile phone into a wallet. Wave your NFC-equipped phone at a store reader and be on your way. NFC has the potential to replace your credit cards, checkbooks and other clumsy payment methods for a single device that you already carry everywhere.
• Public transportation. This could arguably be a subset of mobile payments but it's worth mentioning on its own. In fact, in urban areas with high population density and good public transportation this can be a major driver of NFC adoption. Pilot and commercial programs have already been deployed in many cities of the world -- including my current city Nice, France -- where you can pay the bus, metro or tram with a tap of your phone.
