Card/PIN offers a standard two-factor entry in which a user must first present a valid badge or mobile credential, then enter a 4-9 digit two-factor PIN tied to that credential.
After a badge or mobile credential is presented, the status light on the reader will blink yellow indicating that the reader is waiting for the associated two-factor PIN entry. PIN entries should be started with the star key ( ) and ended with the pound key ( ) (same as standard keypad entries).
