Make NFC tags only readable by one device?

**MrZackarius** · 10-13-2012, 06:57 PM

I've looked everywhere for anything on making it so that only one device would be able to use a NFC tag, however the closest I got to finding the answer was how to make the tag read only. Any help?

I dont think that's how NFC tech is set up.

That's what I figured. It's not a big deal but it would be nice to have some extra security.

You can encrypt the data

You can use Sony smartTag app (Need to install 2 apps on your phone). The Xperia smartTag app doesn’t write anything to the tag, it just associates a set of commands with the found ID/URL! You don't need a Sony device and don't need to buy Sony smartTags ;-) . Much more info;

I think it's a perfectly good answer to the question. It doesn't make the chip unreadable by other devices, of course, but it also ensures that the data on the chip is not meaningful to anyone else.
