Can these be used to make keychains with epoxy resin?

The NFC sensors on MOST phones/devices do work through the thickness of resin-like materials, like phone cases, just be careful not to make the resin too thick on either side. Otherwise, the epoxy or resin should not pose an issue to the internal chip/wiring.

How do you program these? What do you use to write to them and able to rewrite?
