Table 10-13. Verify Crypto
The device increments the associated attempts counter each time prior to verifying the challenge, to prevent attacks. If the
authentication succeeds, the device memorizes this success, clears the attempts counter and returns $90 $00. If the
authentication fails, the device simply returns $69 $00. If the maximum number of trials has been exceeded, the device will
return $69 $00 instead of the INS code, after receiving the header, to indicate the command is unauthorized.
