oldest time card totals are simply overwritten by the new time cards. The
oldest saved card is the card with which the oldest bookings have been
effected prior to the last bookings of the other existing cards.
Advantage:
Disadvantage:
Automatic card deletion by aging :
For this operating mode the function parameter CARD VALIDITY DURATION (see
chapter "Getting Started") has to be active. By additionally indicating the card validity
duration in days you can define when saved cards are deleted automatically by the
recorder.
In this operating mode all cards with card numbers between 000001 and 999999 can
be enabled, too. However, it is not possible to delete cards manually.
The number of days you would program to retain time cards is usually dependent on:
a) Your pay period
b) How many pay periods you want to keep time card totals in the time
recorder
c) How many employees are using the time recorder (including the active pay
period). Remember that the time recorder can only maintain up to 250 time
card totals in its memory (depending on its employee capacity).
Advantage:
Disadvantage:
Manual card deleting
For the manual deletion of time cards, the software feature "DELETING
CARDS" must be enabled.
To avoid exceeding the time recorder's memory capacity, the user or a
supervisor has to delete time cards manually from the recorder at the end of
the pay period.
Quick commissioning and quick start of the recorder with
no need for time card number maintenance .
No control over time card use. Old time cards can still be
used even though they are from a different pay period.
Please note:
When starting a new box of new cards, make sure the
number sequence does not duplicate the numbers of your
old cards.
The deletion of time cards from the time recorder's
memory is controlled and according to a fixed rule. The
chances of the time recorder having to deal with duplicate
numbered time cards is eliminated.
Historical time card total reports for time cards older than
the programmed card validity duration are not possible.
