&gt; That&#x27;s IF you are two inches away, and the object is NOT moving. If the tag is at the edge of the tire (as the picture implies) - where are you going to put the reader so that it can get within 2 inches of the tire?<p>900Mhz RFID tags can be read from over 30ft away.  Can&#x27;t find a video but someone @ defcon was able to get a read from 250ft away using a yagi antenna &amp; power way over the FCC limits.
