Near field communication (NFC) Technology

Nokia N9 With NFC Technology

NFC (near field communication) is a way of exchanging information between your phone and a device such as an NFC credit card reader, an NFC ticket gate or a small object called an RFID tag, by touching them together. You can use an NFC-enabled phone to make fast, convenient purchases, or as an alternative to a travel card. You can also get information such as news or travel updates by touching your phone to an RFID tag embedded in a "smart" poster – or swap electronic business cards with a new contact simply by touching your phones together.



NFC phones are usually equipped with a smart chip to keep confidential information such as your credit card details or travel card information secure.

You can also use your NFC phone to load blank RFID tags with information and mobile phone services that others can access by touching their phones to them.

Why Use NFC ( Near field communication)

NFC makes it quick and convenient to make payments, and to exchange information with smart posters, pocket RFID tags and other people – just by tapping your phone to another NFC device. With an NFC phone you can:

buy the newspaper in a matter of seconds – ideal in the morning when you are in a hurry to get to work
get timetable information by touching your phone to a smart poster
catch a bus, train or tram load your travel ticket into your phone, then just touch your phone to an NFC ticket gate when you want to get moving
swap contact details and other information with friends and colleagues by touching your mobile phones together
make your own RFID tags containing contact information and links to mobile services like news, weather and stock prices to carry round with you or hand out

In the future NFC phones may also be used as:

• Identity documents

• Airline tickets

• Electronic keys for cars, hotel rooms and office buildings
