Are you tired of long queues at toll booths and parking lots? Windshield tags can help you save time and hassle. These RFID tags are affixed to your car’s windshield, allowing contactless payment and access control. RFID technology has revolutionized how we pay tolls, parking, and more. There are two types of RFID tags, passive and active. In this guide, we will explore the working principle of windshield tags and the pros and cons of each type. We will also provide tips on properly placing and removing RFID tags on your windshield.
What is a Windshield Tag?
A windshield tag is a device that uses radio frequency identification (RFID) technology to identify a vehicle. It is usually attached to the inside of a car’s windshield. It allows drivers to quickly and easily pass through toll booths or access controlled areas without stopping to pay or present identification. RFID technology uses a small chip and antenna to send and receive signals to and from a reader. The tag does not require any power source and is activated by the signal from the reader. There are two types of RFID tags, passive and active, with different ranges and costs. Windshield tags are becoming increasingly popular for their convenience and efficiency in tolls, parking, and access control.
In addition to tolls and parking, RFID windshield tags are also used for access control. They can grant access to restricted areas such as gated communities, office buildings, and universities. Windshield tags are a convenient and reliable method for managing access to these areas. Because they can be easily activated or deactivated as needed.

Where do RFID Stickers Go on the Windshield?
RFID stickers or tags are typically placed inside a car’s windshield. The exact location can vary depending on the make and model of the vehicle and the type of RFID tag used.
RFID tags are generally placed in the lower left or right-hand corner of the windshield, behind the rearview mirror. This is because the area behind the mirror is less likely to be obstructed by tinted windows or windshield wipers.
For toll road applications, the RFID tag should be placed on the driver’s side of the windshield to ensure that it is read correctly by the toll reader. The tag should be positioned in a way that is visible to the reader, with the antenna facing the reader.
Following the manufacturer’s instructions is important when placing an RFID tag on your windshield. The tag should be affixed to a clean and dry surface, and the area around the tag should be free from any obstructions that could interfere with its signal. If the tag is not placed correctly, the reader may not read it, resulting in a failed transaction or denied access.

The working principle of windshield tags is based on RFID technology. RFID tags consist of a microchip and an antenna, which work together to transmit information to a reader using radio waves.
The reader sends a radio signal when a car with an RFID tag approaches a reader. The antenna on the tag receives this signal and sends back a response, which contains the tag’s unique identification number.
The reader then captures this response and sends it to a computer system. It uses the information to process the transaction or grant access.
Passive RFID tags do not require a battery, and their operation is based on the energy emitted by the reader. The reader sends out a radio signal that powers the tag. This allows it to respond with its identification number.
On the other hand, Active RFID tags have a built-in battery and can transmit signals over longer distances. They are typically used in applications requiring longer read ranges, such as in toll road systems.
Windshield tags come in two types: passive and active. You can choose according to your daily use of the environment.
Active RFID windshield tags are a type of RFID tag that uses a built-in battery to transmit signals over long distances. These tags are commonly used in toll roads, parking lots, and other applications that require long-range communication between the tag and the reader.
The built-in battery in an active RFID windshield tag allows it to transmit signals even when it is not in the immediate vicinity of a reader. This means an active tag can be read from several meters away, making it ideal for applications that need to be read at high speeds.
Active windshield tags can also be used for real-time tracking of vehicles. The battery-powered tags continuously transmit their location to a reader or base station. This allows it for real-time tracking of the vehicle’s location and movement.
Active RFID tags also have a longer lifespan than passive tags. Because the battery can be replaced when it runs out of power. This means that active windshield tags can be used for many years, making them a cost-effective solution in the long run.
However, active RFID windshield tags are generally more expensive than passive windshield tags and require more maintenance due to the need to replace the battery. Additionally, active tags may be larger and heavier than passive ones, making them more difficult to affix to a windshield.
Passive RFID windshield tags are a type of RFID tag that does not require a battery to operate. These tags are typically used in applications that require proximity communication between the tag and the reader.
Passive RFID windshield tags use radio waves from a reader to power the tag’s microchip and transmit information back to the reader. This means the tag only operates when it is near a reader.
Passive RFID windshield tags are generally smaller and lighter than active tags, which makes them easier to affix to a windshield. They are also less expensive than active tags, making them a more cost-effective solution for many applications.
However, passive RFID windshield tags are limited in range, which may make them less suitable for applications that require long-range communication. They also require a reader with a strong electromagnetic field to power the tag, which may limit their use in certain environments.
How to Place Passive RFID Tag on Windshield
Placing a passive RFID tag on a windshield is a straightforward process. Here are the steps:
- Clean the windshield with a glass cleaner to remove any dirt or grime.
- Peel the backing off the RFID tag to expose the adhesive.
- Place the tag on the windshield, ensuring it is centered and facing the correct direction.
- Press down firmly on the tag to ensure that it is securely attached to the windshield.
- Test the tag with a reader to ensure that it is functioning properly.
It is important to note that the tag’s placement on the windshield can affect its performance. Labels should be placed where they are easily scanned and do not obstruct the driver’s view. Additionally, the tag should not be placed near metallic objects or other sources of interference, as this can affect its ability to communicate with the reader.
How to Remove an RFID Tag from My Windshield
Removing an RFID tag from a windshield can be a bit tricky, as the tag is designed to adhere strongly to the glass. But there are several ways to take down the windshield label:
- Use a heat gun or hair dryer to warm up the adhesive and soften it. Then, use a plastic scraper or credit card to pry the tag off the windshield carefully.
- Use a solvent such as rubbing alcohol, acetone, or Goo Gone to dissolve the adhesive. Rub the solvent into a cloth or cotton ball over the tag until the adhesive dissolves. Then, use a plastic scraper or credit card to remove the tag from the windshield.
It is important to be gentle when removing an RFID tag from a windshield, as excessive force or scraping can damage the glass. If the tag cannot be removed easily, it may be best to leave it in place or seek professional assistance to avoid damaging the windshield.
With the right tools and techniques, removing an RFID tag from a windshield without causing damage is possible. However, it is important to be careful and take appropriate precautions to ensure a safe and successful removal process.
