About NFC
Near field communication (NFC) allows devices such as smartphones to exchange data with other NFC-enabled devices when they’re close by. NFC uses are common. Many retailers have signs at the checkout that tell customers that payment can be made with their phones through Google Wallet. Smartphones with Android 2.3.3 or newer may be configured to send or receive data through this communications standard. However, there are risks involved when using NFC. Researchers at a Pwn2Own contest in Amsterdam showed how NFC can be exploited to gain control over an Android-based smartphone. Researchers at a Black Hat security conference in Las Vegas demonstrated similar vulnerabilities using different techniques.
