# KB: NFC

**From version 2.0.16 and up it's now possible to use NFC to scan tags containing a URL (NDEF).**

By default it is turned off. You can turn NFC on under **Settings > Hardware > NFC**.

When scanning a tag, only **http://**, **https://** and **file://** prefixes are supported, all other tags will display a warning "tag not supported". All URLs will be checked to see if they are permitted in the whitelist (if enabled).

To write a URL to an NFC tag we recommend using [NFC Tools on Google Play](https://play.google.com/store/apps/details?id=com.wakdev.wdnfc).
