About NFC security

NFC (Near Field Communication) is a short-range wireless technology that lets you quickly exchange information between your phone and other NFC-enabled smartphones, smart accessories and smart posters.

When you use NFC to communicate with other devices, you do so securely:

• Range: NFC only works over a short range (a few centimetres), so it's unlikely that you'll connect by mistake. In order to snag your NFC signal, an eavesdropper would need to be uncomfortably close to you. And you would still have to accept the connection before sending or receiving information.
• Encryption: your phone uses the latest security, encryption and authentication features to protect your personal information.
• Control: You can turn off NFC when you’re not using it. But even when NFC is ON, it's automatically disabled when your phone display is locked.

Along with these safeguards, only exchange information with others you know and trust.
