3.5 Battery
The NFC Reader contains an internal backup battery, to keep tamper circuits and critical
memory areas active also during periods without external power.
The minimum lifetime of the battery is 5 years at normal room temperature +20°C/+68°F
and without external power.
3.6 Decommissioning
The NFC Reader may be securely decommissioned by removing the USB cable, opening
the device, and removing the backup battery for minimum 5 seconds. This will assure that
all sensitive data are gone, and that the device is left unusable.
In order to minimise potential fraud, it is recommended that the decommissioned devices
are scrapped and physically damaged, to avoid that the polymer cabinet is used for
fraudulent devices.
