5.3 Automatic PICC Polling
Whenever the reader is connected to the PC, the PICC polling function will start the PICC scanning
to determine if a PICC is placed on or removed within the range of the built-in antenna.
The PICC polling function can be disabled by sending a command to the device through the PCSC
Escape command sequence. To meet the energy saving requirement, special modes are provided for
turning off the antenna field whenever the PICC is inactive, or no PICC is found. The reader will
consume less current in this power saving mode.
