This might not be a hot finding,but I found it to be an interesting topic when I came across it,over at Nokia Upcoming Innovations.This new technology based on short range wireless communication will be the next generation of wireless data interaction,where a “tap” would simply do your wish.NFC relies on the principles of Inductive Coupling where the connecting time is super fast,it only takes tenth of a second.
NFC mobiles can read tags, for example by touching a smart poster with your mobile and it automatically downloads information like web links or telephone numbers, or even enables you to purchase the advertized item. The mobile emits a short-range radio signal that powers up a microchip on the tag, and allows for reading a small amount of data that can be stored on the tag.Mobiles with NFC can also act as an NFC tag, for example, contactless smart card for payments replacing your credit card or electronic transport ticket.
Two NFC enabled mobiles can talk to each others by simply touching them together. They can then exchange data, for example business cards, or can exchange Bluetooth or WLAN parameters to set up a faster data link for transferring files, for example video or photos.
NFC technology is currently mainly aimed at being used with mobile phones. There are three main use cases for NFC:
- card emulation: the NFC device behaves like an existing contactless card
- reader mode: the NFC device is active and read a passive RFID tag, for example for interactive advertising
- P2P mode: two NFC devices are communicating together and exchanging information.
Plenty of applications are possible, such as:
- Mobile ticketing in public transport — an extension of the existing contactless infrastructure.
- Mobile payment — the device acts as a debit/ credit payment card.
- Smart poster — the mobile phone is used to read RFID tags on outdoor billboards in order to get info on the move.
- Bluetooth pairing — in the future pairing of Bluetooth 2.1 devices with NFC support will be as easy as bringing them close together and accepting the pairing. The process of activating Bluetooth on both sides, searching, waiting, pairing and authorization will be replaced by a simple “touch” of the mobile phones.
Other applications in the future could include:
- Electronic ticketing — airline tickets, concert/event tickets, and others
- Electronic money
- Travel cards
- Identity documents
- Mobile commerce
- Electronic keys — car keys, house/office keys, hotel room keys, etc.
- NFC can be used to configure and initiate other wireless network connections such as Bluetooth, Wi-FiUltra-wideband. or
Currently available only on Nokia 6212 Classic and Nokia 6131 NFC,but in the near future it is expected to see this new technology on other Nokia devices too.
