A mysterious low-powered wireless device from Apple has just passed testing by the Federal Communications Commission (FCC) and could be released in the United States in the next few months, according to an FCC filing that was first spotted by French blog Consomac.
It's designated by the model number “A1844”, includes both Bluetooth wireless functionality and built-in NFC and is rated at between 100mA and 700mA (from 5.5V to 13.2V).
