If you are concerned that tinting your car will affect your Smart Tag or RFID, this article is for you.
You have probably heard of tinting that may cause disruptions to Smart Tag signals, is it true? RFIDs can also be installed on the front windscreen of your car.
Will it be affected too? What about other signals such as GPS or even guard house access?
Firstly, we have to understand more on what these signals are and how tinting affects them.
Smart Tag runs on infrared signals, a type of wave that are invisible to our eyes and are also commonly used in remote controllers at home.
RFID on the other hand runs on radio waves which are commonly used by radios and television to receive signals and is also used by GPS systems.
Guard house security access may vary, but are also commonly using infrared based access cards.
Now that we understand most of these signals are classified under either Infrared or Radio waves, how does tint affect these signals?
Heat from the sun comes in 3 different wavelengths, Visible Light, Ultraviolet and Infrared waves.
To block out the sun's heat a tint would have to be able to block out Infrared rays as well.
Thus, if a tint is able to block out a large chunk of heat, it is most likely blocking Infrared signals from your Smart Tag or Guard house security systems as well.
Of course, there are many factors in play such as thickness of the window (the thicker it is, the more the signal gets blocked, and some original window comes with natural IR filters as well) and distance of source of signal to receiver or even device signal strength (battery power/device’s range).
So to sum it up, if your tint is able to block out heat effectively, chances are, they will block out Smart Tag’s and other infrared signals as well.
There are instances whereby some cars with high Infrared rejection tint installed may pass through the Smart Tag (albeit slower detection) and some cars may not.
A common solution for this problem is to cut a small hole on the front windscreen to allow the signal to pass through but it may not be aesthetically acceptable for everyone.
For RFIDs and other radio waves, tints in general do have metal content inside them to allow for rejection of heat.
Metals are known to disrupt signals from radio waves to a certain extent. So, it is advisable to install RFID away from tint, preferably on the headlamp.
As for GPS and cellular reception, most of the time these signals are strong enough to not be affected by tint, so there is not much to worry about.
In summary, we would advise to install the RFID on the headlamp and for Smart Tag, if you plan on getting a tint that blocks out more heat, there may be disruptions to the Smart Tag signals.
Some tints claim to be Smart Tag friendly, however, do take note that if they allow infrared signals from Smart Tag to pass, they may allow more heat to pass as well.
Make sure to do proper research on the specifications to make a better decision.
