2.5.3 Expanded Features
Radio Wave Auto Stop Timing Notification
After successfully activating a smart card with the card polling function, the radio wave
transmission will stop automatically if a certain time period elapses without any data
communication between the NFC module and the smart card. If this happens, it is possible to send
a notification, via either a window message or an event, of the timing when the radio wave
transmission stopped. This notification function can be set effect or disabled, and is set disabled
by default.
2.5.4 Power Control
Power-off When Not in Use
In order to save power, no power is supplied to the NFC module and the ASIC for controlling the
NFC module when the devices are not open. The devices are turned on with the respective open
functions and turned off with the respective close functions.
Control on Power When Terminal is Off
The NFC control software switches on/off of the module when the terminal is turned off.
Furthermore, when the terminal power is switched on again, the NFC control software carries out
relevant process corresponding to what the module was in when the terminal was turned off. The
respective operations which occur when the terminal power is turned on or off are shown in the
table below.

Notes:
1.
When card polling resumes after the power is turned back on, the timeout restarts from
where it ended in the card polling before the power on the terminal is turned off. In addition,
counting time on card polling is suspended while the terminal power is off.
2.
In case the module power is turned off during data communication with smart card and
operation is suspended, the power supply to the smart card is also interrupted so the mode
on the card is reset. Carry out card polling to restart communication.
Control in Virtual Off Mode
In order to save power, the same operations which are performed when the terminal power is
turned off and on are performed when the Virtual Off mode is activated or deactivated.
