Can RFID Technology Pinpoint an Item’s Location to Within Inches?

Generally speaking, it is impossible to read a tag from 1000 feet, or even 30 feet, away and pinpoint an object's location to within a few inches. RFID systems typically locate an object's general position, or determined whether it has passed through a particular portal. On the other hand, there are systems that can identify individual vials in a holder, even when they are inches apart. So it really depends on your application.
