HOW NFC WORKS

 HOW NFC WORKS

           NFC has a short operating range of typically a few centimeters, and works in combination with radio frequency identification (RFID) technology and contactless smart card infrastructure.

Using NFC, your phone can read small amounts of data from RFID service shortcut tags, as well as communicate with other devices. Therefore, when you touch your phone to a RFID tag, the service shortcut contained inside the tag is launched.

RFID tags can be stored in your purse or pocket, or can even be embedded inside posters. You can also create your own personalized service shortcuts by putting data onto an empty RFID tag using your NFC phone. NFC also enables you to share your personalized service shortcuts with other NFC enabled devices.

What’s more, you can make transactions just by touching your phone to a NFC credit card reader or ticket gate. Your payment information, such as credit cards, loyalty cards, or your travel ticket are securely stored in the integrated smart card chip inside your phone.
