### 2/5 — Missing for Smartmotor

*2018-09-14*

Smartmotor App with NFC urgent

**Developer response:** The NFC interface on the iPhones is used by Apple and is only available to a small extent for others (this concerns the read function via NFC). The write function via NFC from the SMART Motor App to the Smart Motor is currently not available for third parties in the iPhone. Only when the NFC interface (read and write function) in the iPhone is available for all can their wishes be further considered.
