Hey all, turns out it was the cards. I got a refund on amazon and sent back the unused ones. I bought NTAG stickers with really good reviews instead and they've been working great. https://smile.amazon.com/gp/product/B0727NYX3B/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

i bought (these)[https://www.amazon.com/gp/product/B0727NYX3B/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1] pre-corona but they dont seem to be prime compatible anymore

I found new ntag215 stickers on Amazon that come with all ntag215, updated the link in my post to it.

Link is also here

Also these are a really good deal that I found and tested/work.

And as always thank you to the people who support this subreddit by purchasing from my shop on Amiibro.com

i bought these https://www.amazon.com/gp/product/B0727NYX3B/ but they took 2 weeks+ (15days) to get here

edit: forgot to mention, they work perfect and i had no issues with any of them. the price has been slowly going up tho cuz i paid 12$ for it 2 weeks ago.

These worked perfectly for me

In the past, I ordered these but I have since switched to these more recently. In both packs, every single one has worked perfectly and I was lucky enough to not get any duds. I have only gotten one dud tag, but those were purchased off Ebay.

That's a decent deal keep an eye on Amazon for "greatestdeals" he is a trusted US seller with positive reviews and free delivery as well.

I don't mind. Here you go: NFC Tags on Amazon

I'm on an iPhone XR and so far so good.
