Smart Chatting application has Smart Function : NFC Function
- Generally, to connect two bluetooth device, one device have to set "Discoverable mode" and other device have to search that device and require connections
- This process has problem of usability. because users don't know the fact that they have to set discoverable mode, and don't know the device name to connect. This process is complex and hard to understand, so people don't use bluetooth
- But Smart Chat application don't need this process, just approach two NFC device then you can connect bluetooth. It is not need to set discoverable mode, search the device and so on. Just approach two NFC device.
- It is easy compared to general bluetooth connection, so it is S.M.A.R.T
