Many of my cards are just repurposed from other things. Lots of hotel keycards can be rewritten to open URLs on phones for example.

I actually have a hotel keycard taped to my washing machine to do some laundry-based automation with my phone. Maybe I should write about that sometime..

Have you thought about getting one implanted?

(glances at chip on my desk)

..yes.

Hopefully getting that installed later this week :)

If you're getting an implant already, why not make it an actual smartcard that you can use for WebAuthN, GPG, SSH etc.? :)

On the other hand, the fear of permanently bricking it or messing up the GlobalPlatform card management key has so far prevented me from doing it myself...

Because those cost $350 as opposed to $89, and the install only costs $60, and there is no stopping you from implanting more than one in different locations.

Many people get the small xEM or xM1 first to play with.

Good point, although at some point you'll want to make sure your reader implements anticollision properly :)
