I own a proxmark3 and would like to clone an ID card that has a MF Classic 1K in it. I would like to clone it to something with a small form factor (fob-size) so that I can integrate it into a wearable.
I would like to purchase the fobs shown here: https://dangerousthings.com/product/acr122u/
but without the reader/writer, as I already have the proxmark. Any suggestions on where to buy just the fobs? I bought some on Amazon but I didn’t read carefully and they turned out not to be sector 0 re-writeable.
