What is NFC?
NFC, Near Field Communication, is a technology for exchanging data at less than 10cm, between two devices equipped with this device. NFC is integrated into most of our mobile terminals in the form of a chip, as well as on certain transport or payment cards.
Three operating modes
NFC has three different operating modes:
Card emulation mode
The mobile terminal works like a contactless card. The mobile phone's SIM card can be used to store encrypted information, and to secure it.
Examples of uses:
- Contactless payment.
- Management of discount coupons or loyalty points in a store.
The mobile equipped with NFC is able to read “tags” (electronic labels), to collect practical information, or to launch an action automatically on a Smartphone.
Examples of uses:
- Tour in a museum
- Automation of a task: change the ringtone of your phone, or launch an application, when the NFC tag approaches.
About NFC tags:
An “NFC tag” is an electronic tag equipped with NFC technology. The advantage is being able to program it, so as to send information to devices located in its field of action. You can buy NFC tags, to program yourself on the Internet.
To program your NFC tag, there are mobile applications such as "NFC Task Launcher", available on Google Play.
Mode peer to peer
This operating mode allows the exchange of information between two devices equipped with NFC.
Example of use :
- An exchange of photos between a tablet and a Smartphone.
- opening the doors of his car
Data security with NFC
The exchange of data between two devices equipped with NFC is secure for two reasons:
- Compliance with standards (14443 and FeliCa) using encryption and authentication algorithms.
- The short communication distance between devices, which greatly reduces the risk of data theft.
How to activate the NFC function on your mobile
Many mobile phones are equipped with the NFC function. This can be offered as an additional option with the package. It can also be an integral part of the mobile's standard functions. In this case, you have to go to the wireless connection settings of your device, in order to activate it.
