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?

Get distance from an RFID Tag [solved] - Arduino Forum

Aug 23, 2016, 10:21 pm Last Edit: Aug 29, 2016, 01:25 pm by Meric

Dear Arduino community,

Hi there,

I've got an IR+RFID guided robot. I have to target many objects in a room, one after the other. All are in a random position. Each one is RFID passive-tagged.

I proceed like that: I target an object with the IR, I reach it, and I check if the target is the right one with an RFID validation.

Now, I would like to validate the objective before to totally reach it �

A way for that is to roughly compare the IR measured distance and the RFID measured distance, and to conclude if the target where we are going is the right one. I even think that compare...
