Firstly, I though I was getting 12 stickers but the packet I received only had 8 stickers so it's a con.
Secondly, these stickers only work on contact. I had an idea to put them on packed items in a carton and that they would react like shopping security tags.
NFC has it uses and the Topaz tags work, but I have yet to find a purpose for contact ID.
