Some vendors have been combining RFID tags with sensors of different kinds. This would allow the tag to report not simply the same information over and over, but identifying information along with current data picked up by the sensor. For example, an RFID tag attached to a leg of lamb could report on the temperature readings of the past 24 hours, to ensure that the meat was properly kept cool.
Over time, the proportion of “scan-it-yourself” aisles in retail stores will increase. Eventually, we may wind up with stores that have mostly “scan-it-yourself” aisles and only a few checkout stations for people who are disabled or unwilling.
