NFC is a set of protocols used to share data between two NFC enabled devices when they are close to each other, typically 4cm or less. This application uses this technology to share data (such as text, contacts, SMS, etc.) between two NFC enabled devices. You can use any file browser application to choose files for sharing. This is a very useful app for anyone who wants to quickly share data between two devices.
To share the data, start the app and hold the devices together with their backs touching each other. When two NFC enabled devices are kept together in back to back manner you can feel the vibrations.
