Set Automatic Picc Polling - ACS ACM1281U-C7 Reference Manual

5.2.7.

Set Automatic PICC Polling

This command is used to set the reader's polling mode.
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/removed from the built-in antenna.
You can send a command to disable the PICC polling function by sending a command through the
PC/SC Escape Command interface. 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 power saving mode.
