Hardware any good uses for nfc tags?

[natanelho]

I bought a lot of nfc tags to use as amiibo, in fact I bought the smallest quantity I found and it still is a lot
I wont use them all for amiibo...
can anybody suggest a good use for them?
I have no idea what more can I do with them other then setting a predefined set of settings to my phone...

Use them to launch games, to activate your lights when you enter your room... see them as a coded switch

I backup my wifi network settings to them (in android 6, at least, go to wifi settings and long press the connection) - pretty handy when you reformat to try different roms multiple times a day

give (or sell) some to users who don't have a NFC phone. (though, it might be illegal to sell an already flashed one here).
or give/sell them blank to users who don't want to buy many pieces like you did? (who many did you buy? I found a pack of 10 pieces only on amazon)

I don't have idea what you could use them for other than gaming or settings backup.
edit:
ah, maybe it can be used as badge access for garages or building lobby (if you use such keys)

MORE. AMIIBO. PIRACY. You can also stylize them within cards and sell them for decent prices.

If you could make me an amiibo and I pay shipping that would be great.

the NFC tag has two sections : the first one has few bytes which are write-once (and contains the uniqueID to know it's an amiibo, and which one), and the last part which is rewritable and contains the NFC data.
