5-3-5 Polling Single Auto Read (PR)
Immediately after receiving the Polling Single Auto Read Command, the Reader/Writer returns a re-
sponse 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) com-
mand.
