Broken/Spares being sold in the Lab?

The place I got it no longer stock them.
HERE is a link that has some.

If you search for:-
Smart nail N2M = Mifare S50 (different from my box though, I may have swapped them)
Smart nail N2F = NFC
Smart nail N2L = LED

Again typical Aliexpress, it’s like a box of chocolates…


I’ve used Star Security chips as well. Very good chip. Do not implant for obvious reasons, even if the cheap injectable is alluring.
