Cloning Tags with Nfc Interactor

With the new Nfc Interactor 4.0 you can easily clone tags. This is incredibly useful if you have a reference tag and need to create multiple copies of it.

To do so, simply read the tag with the app – Nfc Interactor will parse its contents and print them on the info screen. Now, tap on the blue text of the tag contents.

A context menu appears, which allows you to edit or clone the collected tag contents. Simply select “Clone”, and the app immediately switches to the tag write mode. Touch as many new Nfc tags as you like – Nfc Interactor will write an exact 1:1 copy of the NDEF message to all other tags, creating duplicates.

For this feature to work, you need to activate the setting to save all collected NDEF messages to files – as the raw tag contents are then cached to a file by the app, which can be duplicated & written to other tags. This setting is activated by default, so you’re ready to go after you installed the app!

Note that this feature creates a copy of the NDEF message of the tag, and not of the raw bytes on the tag. An advantage of this approach is that it’s possible to copy the message to other tag types, which are bigger, smaller or use a different data structure to store the NDEF messages. So you don’t need to worry if your tag isn’t exactly the same type as the source tag; duplicating the contents always works as long as the tag meets the minimum size for the message.

When creating tag copies, keep in mind that tags can also have individual, tag-specific and non-writable IDs, in addition to the tag content that can be copied.
