Ask HN: What can I do with NFC stickers?

[qute]

I got myself several NFC stickers. My phone can read/write the information on them. What cool stuff could I do with them?

(googling gave me either simple options like 'put a wifi password on it' or too generic ones like 'use it as a trigger in Tasker on the smartphone')

you can program them with a url so when you tap an android phone it opens the url if NFC is turned on in the phone. You can also add a counter to the url
