About

Q

Read full description

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).
