How RFID windshield stickers work
When a vehicle equipped with an RFID windshield sticker approaches a checkpoint, such as a toll booth or access gate, a UHF RFID reader installed at the location emits a radio signal. The passive RFID tag on the windshield receives this signal and responds by transmitting its unique identification number back to the reader. The system then verifies this ID against a database to determine whether to grant access, record the event, or trigger other automated actions.
Where do you stick RFID stickers on a car
RFID stickers are typically placed on the inside of the windshield, where they have a clear line of sight to external RFID readers. The most common placement is behind the rear-view mirror or in the upper-left corner (driver’s side) of the windshield. These areas are preferred because they minimize obstruction and avoid interference from metallic tinting or electronic components. It’s important to avoid sticking the RFID tag over defroster wires, sensor arrays, or metalized coatings, as these can block or weaken the RFID signal. In vehicles where the windshield contains metallic elements or embedded technology that interferes with signal transmission, alternative placements such as the dashboard, headlights, or even license plate area may be used, depending on the tag design and system requirements.
How to remove RFID windshield sticker without damaging car
To safely remove an RFID sticker from a car’s windshield without causing damage, start by gently heating the sticker using a hairdryer set to low heat for about 30 to 60 seconds. This softens the adhesive, making the sticker easier to peel off. Once warmed, use a plastic scraper, an old credit card, or your fingernail to lift a corner of the sticker and slowly peel it away at a low angle. If any adhesive residue remains on the glass, it can be cleaned using a glass-safe adhesive remover or a small amount of rubbing alcohol applied with a microfiber cloth. It’s important to avoid using metal tools or harsh chemicals, as these may scratch the windshield or damage surrounding surfaces.
