My card is not detected…
Double check that the chip card reader is connected to your computer and its recognized by the operating system.
Make sure you put your card on the right side. In general, the chip should be on top (this is the case with the Satochip smart card reader).
If you are on Linux, you may need to install the smartcard driver if the card is not detected. You can do it, for example on Ubuntu, with the following command line: sudo apt install pcscd
If you are on Windows, be sure your chip card reader is using the latest driver.
