Thanks much for the video. I did little bit more digging and found
the following thread where the developer for NFC Task Launcher states: "
It's detecting they can't be written and mapping the actions locally. To allow for cross device portability the payload is also pushed to a cloud service we provide. This way any device can also use that tag." To which
another poster responds, "
OK i see what you're saying. I put the device into airplane mode but with nfc on and retested. It did not write.
However this begs the question....this whole cloud service thing is a huge security violation and does not seem to be documented anywhere. The play store permission list does not mention this use of the internet permission. This is a HUGE DEAL. You appear to be saving the information from thousands of tags in this cloud service...this could include passwords or other personal information."
Mac58, would you mind showing this scenario in your/another video: all connectivity disabled (i.e. wifi off, airplane mode on, etc.), "write" to tag, then try to read tag to verify if tag actually "written"? Thanks.
Personally, I don't know how I feel about a 3rd party storing this data. Besides potential security concerns, there's also reliability and continuity concerns. What happens down the road if the current developer cannot or does not wish to support the NFC Task Launcher cloud service; do all the tags that used to "work" with NFC Task Launcher become obsolete/useless? Is the use of NFC Task Launcher and the behind-the-scene cloud service the lesser of two evils when dealing with NFC tags that are NOT standards-compliant?
If this data was stored locally on the phone, I would feel that both my areas of concern would be allayed.
