When I did automotive work, the company used RFID tags to track the tires coming in and out of the workshop. They were about four times the size of what Charasanya showed, but they had a range of about four hundred feet. You could pick them up with the wand from outside the building.
Of course, going with the cheapest supplier, the tags fried if they got wet or touched metal. That was absolutely perfect for tires being stored on metal racks in a leaky building.
I would expect by SR time they would have the range considerably extended.
