Smart Card Tab
iCLASS Card Protection
The grid on the right shows the protected blocks in red:
You can protect multiple areas simply by choosing new values
for each of these entries. You can clear any protected area
by choosing the application area and choosing Available for
Reader's Evaluation in the Select Protection drop down menu.
When you protect blocks in even application areas (0, 2, 4,
etc.), blocks are used from the left to the right, that is, starting
at block 6 and working up; when you protect areas in odd
application areas (1, 3, 5, etc.), blocks are used from right to
left, that is, starting at 31 and working down.
If you protect both even and odd sections in any pair (for
example, if you protect parts of both area 0 area 1), then the
fingerprint reader can't use that pair at all so the entire area is
marked as protected.
Î Programmed iCLASS cards require application area 0 to
be blocked off. To do this, click Select Application Area
and pick Application Area 0 from the drop down menu.
Then click Select Protection and choose Protect 26
blocks.
Resetting Old Card Keys
To change the key for a previously used iCLASS card,
the reader must know what the old key is—this prevents
unauthorized people from converting other cards to work with
your system. HandNet Lite keeps track of what the last key
you used was, so most of the time, you don't need to change
this entry.
For example, suppose you originally set the key to 1234123412341234 and then you entered a New Reader Key of
5678567856785678. HandNet Lite remembers the old key; it would automatically change cards to the new key if you set it to
automatically update keys (see
However, suppose in January you set the key to 1234123412341234, in February change it to 5678567856785678, and in March
change it again to 9ABC9ABC9ABC9ABC. Cards that got used during February would have been updated to 5678567856785678;
cards that didn't get used during February would still have January's key of 1234123412341234. The reader can automatically
update those cards with the most recent old key (5678567856785678), but it would no longer recognize the prior old key of
1234123412341234. If you have a situation like this, to update the older cards, you must manually indicate what old key to use by
checking the Reset Old Key checkbox and then entering the appropriate value in the old key entries.
If you have an older card and know that one of several keys was used on it but aren't sure which one, enter the various old keys in
turn here, trying to update the card each time.
You can avoid ever having to do this if you make sure that all cards get updated each time you change your key.
Automatic Key Update on page 38).
