The Master Reader/Writer will wait for an RF Tag to enter the communications field and then
communicate with the RF Tag. Here, if an RF Tag communications error occurs, the Reader/Writer will
return a response to the host device, and processing will end. If communications with the RF Tag end
normally, processing returns to step 3.
