With this option, users can both use the conventional way or the
smart card for user authentication. Each user will have his / her own smart card,
which stores the user information including the name, company & branch code, and
the fingerprint information.
Why need the smart card?
Normally, all the users’ information is stored in the internal memory of each device,
including the fingerprint template (a mathematical representation of the fingerprint
image). The information requires a lot of memory space. Therefore, there is a
limitation of the maximum number of users stored, and the current maximum number
of users is 1,000.
With the smart card, since the user information is no longer stores in the internal
memory, the device can thus support many more users (i.e., up to 5,000 users).
Although it is easy to replicate all the user information across all devices within a
Master / Slave configuration, it is not too easy to replicate the data with other
branches of the company in different geographic locations. This problem can be
solved by using smart card to store the user information, and the user will carry his /
her own information with him / her.
Also, this option allows almost-instant verification during the authorized period for
entry, thus enables high-traffic applications (such as during the beginning of the day
when everyone gets to the office at about the same time).
Internal Memory vs. Smart Card Memory
The internal user database of the device is divided into two parts: the
Internal
Memory
& the
Smart Card Memory
. The Internal Memory acts as both the
temporary storage
to store the user information (for transferring to the smart card
later), and as the
permanent storage
for the auto-match purpose. The maximum
number of users stored in the Internal Memory is 20.
The Smart Card Memory stores the information of the smart cards that have been
registered to the device. The information includes the serial number of the card, the
user name, the departments the user belongs to, the access rights of the user, but
without
the fingerprint information. The maximum number of smart card users stored
in the Smart Card Memory is up to 5,000.
