Well, I think I could extend my SPR332 [mod][1]: * Add a push-button that one has to press to close the C7 circuit for I/O. Without that button pressed, the smart card cannot communicate with the reader. That means, for every operation, one would need to hold that button, kind of – but not as elegantly – as with a YubiKey.
* Using some electronics detect when the green PIN pad ✓-button is pressed to confirm PIN entry on the reader. Let it trigger a timer that cuts I/O for good after a few minutes. Very likely there are some issues that I don’t see at the moment.
