Reading from/Writing to Tags
POLLING AUTO READ (PR)
When the host device sends a POLLING AUTO READ command to the Controller, the Controller
immediately returns a response to the host device indicating reception of the command. Then the
Controller waits for the approaching Tag and reads the data of the Tag when the ID Tag is in the
communications area.
When the Tag is in the communications area, the host device can use a subcommand to request the
command processing results.
