Smart Card Tab
Automatic Key Update
Some administrators want any reader to update the key; other administrators prefer to only let selected readers update cards. For
example, for top security, you might only let a non-networked reader in a security office update cards so that was the only place
they could be updated. To do this, the administrator would create one iCLASS definition for the public readers (with Automatic Key
Update unchecked), and another iClass definition (Automatic Key Update checked) for the administrative reader.
If you disable automatic updates here, you can still manually update keys using the reader command menus.
If you return to this screen, this entry defaults to Do Not Change; this means that whatever setting was previously entered will
continue to be used. If you're editing a previously created definition, click the button to see what the current settings are. (This
button doesn't do anything when creating a new definition.)
Your choices are:
Do Not Change: Use the previously entered setting.
Disable Auto Key Update: This prevents the reader from ever changing a key. With this setting, to update cards, you would have
to use a reader associated with another iCLASS definition that allowed updates, or you would have to manually update cards with
the reader's command menus.
Start Unlimited Auto Key Update: If any card with the old key is used, this automatically updates the card to the new key. There's
no limit to the number of cards that can be updated, and no limit on the date range.
Start Limited Auto Key Update: If any card is used that currently has this old key, this automatically updates the card to the new
key until the number of cards and/or date specified in the following two entries is reached. For example, if you had 20 employees,
you might set this to only automatically update 20 cards; once that was done, cards would not be automatically updated until you
changed the key again. You could also specify a date; cards would then be automatically updated until that date, but would not be
updated after that date.
Specify (protect) application areas
Only check this box if you are sharing the iCLASS card with another iCLASS device that doesn't automatically determine the
template location on the card. If fingerprint readers are the only iCLASS device that you use with your cards, or if you use other
device that also automatically choose an available space to store information, then you don't need to change this setting.
For example, Schlage Biometrics hand readers always store their templates in blocks 19–31 of area 1. If you were using the same
iCLASS cards with both Schlage Biometrics hand readers and Schlage Biometrics fingerprint readers, you'd have to protect these
blocks so a fingerprint template wouldn't get written in this area; if it did, the hand reader would write a template over it.
To protect these blocks, check the box by Specify (protect) application areas, click Select Application Area and pick Application
Area 1 from the drop down menu, and click Select Protection and choose Protect 13 blocks from the menu.
