Example 3: Authentication. A reader already in Security Level 3 or 4 is put into the Authenticated
Mode, allowed to stay in that mode for a time, then Deactivated.
; This example demonstrates the Authentication Sequence.
; It is not scripted; some of the data is deliberately randomized. This
; makes it impossible for a simple script to produce the correct results.
; As an example it shows all the steps in authentication and deactivation.
; It assumes the reader is at Security Level 4, with the DUKPT KSN
; counter set to 2.
09 00 ; Get current KSN (should be FFFF9876543210E00002)
; Send the Activate Authenticated Mode command (4 minutes)
