DIY P71 JCOP Ring

Hi,

Would like to share some projects of mine with the community. This is my very own DIY Java Card Ring. Thanks to @StarGate01 for the bare jcop chip. I’ve used a ceramic ring, some wire, a P71 chip, some super glue and baking soda and put together my magic ring. I use it every day for my Tesla as key, YK-Oath as 2nd factor, PIV-Applet for Mail-signing, ssh and so on. More to come in future.

Regards, Peppy.
