Poll for Token with ATS (2C-0E)
After Pass-Through Mode is started, the device will not poll for any cards until it receives the
Poll for Token
command. This command tells the device to start polling for a Type A or Type B
PICC until a PICC is detected or a timeout occurs.
This command automatically turns the RF Antenna on.
If the device detects a PICC is detected within the specified time limit, it activates the PICC and
returns card related data such as the Serial Number to the terminal.
If the device does not detect a PICC within the specified time limit, it stops polling and
responds to the terminal that no card was found. No card related data is returned in this case.
