RFID and distance measurement

Hello Guys,

I have a new project that I want use RFID to verify ID of item and I need measurement distance from reader to TAG. The maximum distance between the reader to TAG is about 7 cm and I want know distance between reader to TAG with accuracy about 1 cm.

Is it possible?
