5-4-7 Polling Single Auto Read (PR)
Immediately after receiving the Polling Single Auto Read Command, the Reader/Writer returns a
response indicating the acceptance of the command, and waits for a Tag to enter the communications area
of the Antenna. Then it reads the data of the entering Tag. The host can inquire of the Reader/Writer
about the results of communications processing using the Polling Check (PC) command.
