Our E-470 tollway has a windshield sticker no bigger than any other RFID and can be read just fine. Highways are now getting all kinds of fancy electronics and I have no doubt that they could read an RFID in your wallet or purse.

YOU’LL NOTICE those antenna (the Yagis seen at the toll booths pointing down at trafic!) used are in the 900 MHz range.

This a FAR CRY from the 200 kHz ‘coupled fields’ systems used on merchandise (and library books!)

Too many ppl believe in ‘magic’ on this stuff; where are all the board EEs and physicists?
