I am so sorry to be asking so many questions on different topics. But I want to make sure I do this right. If I attach one of the magnets to a piece of card stock and loop, it around the metal can with an elastic band, will the tag still be able to be read by my phone? I guess what I’m getting at is no matter how you attach it, the magnets or metal cans should always be used with magnets. Thank you so much for all of your help.
