Windshield is the best location. The RFID signal may be blocked or shortened it's range easily enough by the metal sheet of the car if placed in the wrong location.
Of course, if you want to block the signal intentionally, a simple sheet of metal mesh is enough to shield it (Faraday cage principle).

Reading tags on individual store items will be tricky, however, and spies will find it hard to track items with handheld readers or those mounted in doorways. A sheet of aluminum foil is many times thicker than it needs to be to shield an RFID signal, said ThingMagic's Reynolds. The signals are also disrupted by human flesh, which is made mostly of salt water: an RFID tag inside your fist cannot be read.
RFID tag systems, said Reynolds, also suffer from limited range. The readers -- due to FCC tag power limits and design limitations on tag antenna sizes -- work at distances up to about 20 meters. "In practice we see far less read range than that," he said.
Reynolds said he'd favor a "modest increase" in the receiver sensitivity limits set by the FCC.
But he pointed out that a laminated anti-static bag, for example, would not be readable by even a more potent system.

RFID tags differ greatly depending on application. The ones used for in-store security and price-tagging is the low power type. I would think the ones used for vehicles will be more powerful. But of course, will still suffer similar problems of interference or shielding (as experienced by those using e-pass payment for NLEX and SLEX).

September 24th, 2009 02:38 PM #56tingin ko mas madali itong ma roll out since sticker / RFID lang na dapat idikit sa sasakyan... ang mas matagal nito ay yung hardware / network infrastructure sa mga readers...
imagine.. even if a scanner / reader can read to a range of 100 feet... impossible naman makapag lagay ng reader ang government at every street kung talagang pang surveillance... the most they can do is put in select spots and do a count... say during peak hours ilan ang dumadaan, off peak hours ilang vehicles... for statistics malalaman din kung public private etc...
si Honorable Congressman Casino naghahabol na makapag latag ng TRO bago ma implement ito by Oct1.. let's see what happens...

mukhang mahabang pila ang pagkuha ng RFID kasi each RFID has to be encoded with the vehicles data before they issue it to you.
yung verification nga lang ng insurance ilan taon bago nila naayos, tapos nalulusutan pa di sila.
same company ba ang hahawak ng rfid at nung insurance verification? stradcom ba yun?

yup! same company ulit....
ang balita a big fat man is behind stradcom...*cough*FG*cough*.
P350* ilan ba ang registered vehicles ngayon? plus pa mga motorcycle then every year ilan ba ang bagong kotse nadagdag? ang laking pera!
bakit ba everytime na malapit ang election eh meron bagong project ang LTO? road user's tax...anyone?
anyway, do we have a choice? kung ano gusto nila eh di sundin na lang...wala naman talaga tayong magagawa eh...
