Ahh, interesting. I suppose then testing when it’s possible to insert/remove a contact card without disruption would give me a good idea of what to expect from a contactless card. Thanks for the info! EDIT: It seems like requesting a decryption, removing/inserting a Yubikey while the pinentry screen is up, then entering the PIN does not work. I suppose I've broken the session then. So I'm guessing to use a ring form-factor card, I'd have to keep the ring above the reader during the whole operation, which means I'd have to remove it to place on the reader and can't just keep it on/tap when needed. Hm. That's a bit unfortunate. (Also possible the Yubikey behaves differently as it's both reader and card in one... I don't have a dedicated reader set up to test with at the moment.) EDIT 2: For anyone who comes across this later: no, a dedicated reader behaves the same way; once the pinentry prompt is open, you can't remove the card and reinsert without invalidating that request.
