Q-Transfer 4+

The Q-Transfer is able to send/receive data to/from NX1 @ ~8Kbps speed via NFC protocol, which is not practical to transfer bulky data while fairly convenient to exchange small chunk of data.
Unlike a standard NFC tag, which is unpowered, the NX1 NFC tag function requires power to operate on exchanging data with the iDevice. When the close proximity is met between iDevice & NFC tag, the Q-Transfer app is invoked automatically for Read / Write / Recorder.
Practical usage scenarios are listed below:
Read: User manual provided @ iDevice upon product ID detection while tapping on NFC tag antenna @ NX1.
Read: Game statistics read out for display @ iDevice.
Write: Content replacement by writing new data, like LED flash pattern, sound, and even program codes onto NX1.
Recorder: Record voice memo @ iDevice, compressed, and transferred to NX1 for playback.
During data transfer period, music prompts are provided to indicate start / transfer-in-progress / end (complete or incomplete).
