What system is most widely used for vehicle tracking RFID or GPS?

 

There are a few different ways to track a vehicle, but which one is the best for you? RFID or GPS? Both have their pros and cons, so let's take a closer look at each option.

RFID

RFID stands for Radio Frequency Identification. This technology uses radio waves to communicate between a tag and a reader. The tag is usually attached to the asset, in this case the vehicle. The reader is usually placed near the entrance/exit of a secured area. When the tag comes within range of the reader, the information on the tag is read and transmitted to a computer for processing.

Pros: 

• RFID tags are very small and can be easily hidden on a vehicle.
• RFID tags do not require a line of sight to be read, so they can be read even if the vehicle is in a garage or other enclosed space.
• RFID tags can be read from a distance, so you don't have to be right next to the vehicle to track it.

Cons: 

• RFID tags are relatively expensive.
• RFID tags require a special reader to work, so you would need to have one installed at any secured area you want to track the vehicle.
• RFID tags can be jammed or blocked by metal objects, so they may not work reliably in all environments.
• RFID tags can be duplicated, so it's possible for someone to make a counterfeit tag that would allow them to access a secured area.

GPS

GPS stands for Global Positioning System. This technology uses a network of satellites to triangulate the position of a GPS receiver. The receiver then uses this information to calculate the latitude, longitude, and altitude of the device.

Pros:

• GPS tags are very accurate, so you can track a vehicle to within a few feet.
• GPS tags are relatively inexpensive.
• GPS tags do not require a special reader, so you can track a vehicle with just a GPS receiver.
• GPS tags are not affected by metal objects or interference, so they will work reliably in all environments.
• GPS tags cannot be duplicated, so you can be sure that the tag is coming from the actual vehicle.

Cons: 

• GPS tags require a line of sight to the satellite in order to work, so they will not work indoors or in other enclosed spaces.
• GPS tags are larger than RFID tags, so they may be more difficult to hide on a vehicle.
• GPS tags can be turned off, so a vehicle could enter a secured area without being tracked.

So, which is better - RFID or GPS? It depends on your needs. If you need to track a vehicle indoors or in other enclosed spaces, then RFID is the better option.  If you need to track a vehicle outdoors and don't mind if it's hidden, then GPS is the better option. If you need to track a vehicle outdoors and want to be able to see it, then GPS is the better option. Ultimately, the decision comes down to what you need to track and where you need to track it.
