Trigger - NFC Tag
The trigger NFC Tag executes the flow when an NFC tag is detected.
You can either write a special ID to the NFC tag that will be used to identify the tag and execute the flow (this is the recommended option to use when you have a writable NFC tag) or you can also read the ID of an existing NFC tag. This is especially useful for read-only NFC tags like the ones often found in credit cards or read-only NFC tags (Live Tags, Smart Tags etc.) of some device manufacturers. Please also check the
Tip in the settings section of this page.
Note: Not all NFC tags are supported.

Multiple IDs can be written to the tag but the tag IDs must contain only regular characters, underscore and numbers.
Option Write alternate tag information on the writer screen allows to define whether or not different type of information should be written to the NFC tag. Some devices show a warning dialog when a regular Automagic NFC tag is scanned since the tag contains a Web-URL. Writing an alternate tag uses a different URL that avoids this warning message.
Android 4+: Option Include Android Application Record on the writer screen allows to define whether or not an additional AAR (Android Application Record) should be written to the tag. An AAR uses slightly more space on the NFC tag but ensures that the tag is preferably handled by Automagic and not by another app.
Tip: Some devices contain apps that can handle generic NFC tags and are shown in a selection list when an NFC tag is scanned. Uninstall or deactivate unused apps when the selection dialog bugs you. You can deactivate apps in the system settings on an Android 4+ device (System settings->Apps->All, Select the app->Deactivate).
For example, you can disable the app Tags on a Galaxy Nexus to prevent the selection list from showing.
