Hello, I am developing a smartcard CTK extension for macOS. I have trouble to smartcard logon the first time after a reboot or a logout (e.g. when there is the text "Your password is required to enable touch id"). Trouble = I'm not asked for the PIN. But time to time after a logout (from whatever account), I can login with the smartcard. After a lockscreen I can always login with the smartcard. Is there an easy way to debug the logon process ? Regards, ++dom

Hello, I'm an iOS and macOS developer. It is unclear to me if the "Smart Card Token Extension" on iOS can address Smart Card using NFC or CCID or both. Please tell us what is the current status. When creating the extension, you can provision an AID, what this information is used for ? Can't I use multiple application (hence multiple AIDs, let say one normal and one for qualified signature) on the SmartCard with the same scext ? It is worth asking the questions before diving into useless coding. Regards, ++dom
