Hi Jake, I think the driving mode can be configure to speak to you when you get a message (like the briefing alarm does in the S3 clock app). Driving Mode may be a Samsung feature as I cannot find anyway of toggling this using a tag.

I have found the app Tasker very useful as well for automating actions based on time/location. Links into NFC Launcher as well to use with tags.

Hmm. Dunno. More capable that qrcodes though.

How they're linked I don't know. I've not tried the tag on my media box with anything other than the S3 I used to set it up. I suspect it won't do anything if I put the Nexus 7 next to it. Probably even if I have the same "task launcher" app on the nexus with a tag of the same in it. I guess the tag is given some kind of guid when written to by the S3 which would need to match that in teh same app on the Nexus to work. Dunno yet though.

Are these not just QRCodes without the ink? Swiping instead of scanning or do the tags 'do' more in terms of linking them to a device so only you can use them?

Hadn't really thought about it until now, but no, I wouldn't trust anything in the wild.

Ah yes, good old NFC. You can program them to do all sorts of dirty jobs from reading the meter, connecting to Spotify, and of course, stealing credit card information.

Obviously for your own usage it's not too much of an issue, but would you trust an NFC tag out in the wild? I wouldn't. http://www.techrepublic.com/blog/security/scariest-stuff-from-blackhat-2012/8195
