NFC compatible smartphones are smartphones with built-in Near Field Communication (NFC) function. These smartphones have Android 2.3.3 operating system or newer. Look for the NFC logo on a smartphone or mobile device to ensure that it is NFC compatible. 

NOTES: Currently Apple iPhone mobile device and other Apple iOS devices do not support the NFC feature. NFC function is not compatible on smartphones with Android 3. x operating system. To use the NFC function, the NFC Easy Connect application needs to be downloaded and installed on the smartphone. This application can be downloaded from the Google Play store. 

NOTE: Some smartphones with the Android 4.0 operating system may already have an app installed that has similar functions. Refer to the manual supplied with the smartphone for additional details.

Near Field Communication (NFC) is a technology that allows you to transfer information between your phone and other devices just by touching them together. Like Bluetooth, it's a standard system that works across devices from different manufacturers and it makes it more convenient to make transactions, exchange digital content and connect devices. You can transfer information between your phone and other phones and mobile devices, payment devices and home audio and video devices. For example, you can share web addresses, contacts, phone numbers, music tracks, videos or photos. NFC tags are small programmed information areas that can be embedded on posters, billboard advertisements or next to products in retail stores. Touching a tag gives you additional information such as maps, web addresses and movie trailers. NFC is activated by bringing two NFC-compatible devices together.The maximum reading distance is about one centimetre, which helps prevent unauthorised communications.

If the NFC application is installed in your smartphone, the selection screen may appear when you touch the smartphone to the Sony wireless boombox, Micro HiFi Component system or car stereo. To resolve this issue, select the NFC Easy Connect application and set it to use default. The application will start automatically the next time the NFC function is used. 

NOTES: To change the settings of the NFC Easy Connect application, check the instruction manual supplied with the smartphone. The NFC Easy Connect app is not required if you are using Android 4.1 or later operating systems.
