The Native (UXP and RDP) redirection type must be selected for the Smart card readers device class in Peripheral devices redirection settings group in the Peripherals section of Setup GUI to enable the native redirection of smart card readers for RDP sessions (in RDP Client and VERDE VDI Client operation modes).
The ‘certutil -scinfo’ command can be used inside the RDP session to verify the operability of the redirected smart card reader and the smart card inserted into the reader. With well working redirection it will ask for card’s PIN and display the certificate stored on the card.
