Subject: Spyrus Battery Power
Consumption
Sitting on the
Shelf
The Spyrus units lose battery power just
sitting on the shelf. After installing a fresh set of batteries, it
would take approx. one year before they died.
Operation
Scenario
On a fresh set of batteries, and based on the
operation model noted below, the Spyrus can program approx. 1300 smart
cards before needing another fresh set of
batteries.
Operation model: Assumed each
operation takes 2 minutes, and during the two minutes operation, the smart
card is powered on for 20 seconds.
During the 2
minutes operation, the PAR2 is running at full power for 30 seconds, and
low power for 90 seconds. When the PAR2 is
waiting for a key
input, or processing a command from the Diebold application, it would be
running in the low power mode.
As an example, taking both power consumption factors into account,
a Spyrus unit never used after fresh batteries were installed and sitting on
a shelf for 6 months would have 50% battery power left. It would
therefore be able to program approx. 650 smart cards (half of the
1300.)
