NFC tag scanned

An action block that waits for an NFC tag to be scanned by the user.

The fiber will pause until a tag has been scanned.

Use the Write tag in the tag section, or the Write tag block, to write tags. Don’t rely on unwritten Any type of tags, some generate a random ID every time they’re discovered, some doesn’t have an ID at all.

Tags can also be written by apps capable of writing Android Application Record (AAR), write it as the first NDEF record, with package name com.llamalab.automate.

Tags written without a type may cause the system app choice dialog to open when scanned. To hide Automate from being a choice, disable the “Detect all kind of NFC tags” option in settings. To hide any other app, e.g. the system “Tags” app, try “Disable” it in system Apps settings.

Scanning tags may not work while the device is locked.
