With increasing technological advances our day to day life is complimented by hosts of technical equipments and services. Most of these have come to become our need, something we can’t function without. Take smartphone for example, from email to phone numbers and contacts, photos, and our digital payment applications, even our online grocery order, everything is on our smartphones. From entry into our apartment to the functioning of our kitchen and bathroom, everything is a proof that we depend on technology a lot.
Electronic Vehicle identification is also one such technology application that we are getting into. Not wading into the side effects of such application, we can certainly say that it is useful. Electronic vehicle identification can automate our entry into our society, parking lot, track our vehicle in a limited area, and ease the toll collection amongst many other things.
Passive UHF RFID system for electronic vehicle identification:
Electronic vehicle identification mostly employs active RFID transponders for all practical purposes. Be it tracking vehicle on route or traffic management by electronic vehicle identification on high traffic routes, active transponders are the best option but this s not a cost effective option. Since active RFID tags come with their own power supply (batteries), these are big in size and costly as well.
Passive RFID transponders on the other hand when used in ultra high frequency range of 860-960 mHz can be a cost effective option for various electronic vehicle identification needs. These UHF Passive RFID tags do not come with batteries and provide short range working than active RFID transponders but are small in size, durable and can be attached to vehicle easily. These transponders also follow the communication protocol under ISO/IEC 18000-6c, EPCGlobal class 1 and class 2 respectively.
Passive UHF RFID tags on vehicle number plate and windshield:
In electronic vehicle identification, passive UHF RFID transponders are used in vehicles for access control and automated toll collection, like use of FASTag on vehicle windshield in India.
In this case, the FASTag, which is basically a RFID tag linked to a digital wallet of the vehicle owner, contains vehicle details and becomes active when the vehicle nears a toll booth. The RFID reader antennae installed at toll booth send radio signals to the FASTag, activating the tag and the toll is deducted as the vehicle crosses the toll booth.
The passive UHF RFID tag can also be attached to vehicle number plate with slot antenna and works the same way as FASTag. The tag is activated when your vehicle nears a boom barrier at your society gate or parking lot and grants access as required.
What are the benefits of electronic vehicle identification with RFID?
Using RFID for electronic vehicle identification has many obvious benefits that can range from access control to tracking a vehicle in vicinity or managing traffic on a busy stretch of a road. Since RFID system not only can identify, trace and track a vehicle but provide you with insightful data via software and cloud system that stores the data, the application of RFID is being customize to various needs.
Using RFID in Electronic Vehicle Identification, a great degree of automation can be introduced in many activities that require you to come out of the vehicle. On society gates, sure security guards are present who open and close the gate for you, by identifying your vehicle, but what if there is a new security guard? Then you’ve to come out of the vehicle. I’ve seen people getting into arguments over that. Using RFID system with a database of residents, this can be completely avoided. This improves resident experience as well.
Traffic monitoring, traffic flow statistics, and traffic scheduling can also be done by employing RFID in vehicles.
