With the rise of digital payments and automated toll collection, FASTag has become an essential component for vehicles on Indian highways. It uses Radio Frequency Identification (RFID) technology to facilitate seamless toll transactions without needing to stop the vehicle. Understanding the RFID tag and its functions helps drivers manage toll payments efficiently.
The RFID tag: FASTag
FASTag uses RFID technology to transmit data between the tag and the RFID reader at the toll booth. The tag, fixed on a vehicle’s windscreen, is linked to the vehicle owner’s prepaid account or bank wallet. When the vehicle passes through a toll plaza, RFID readers scan the tag, verify details on the National Electronic Toll Collection (NETC) system and automatically deduct the applicable toll, eliminating the need for cash transactions.
How does RFID work in FASTag?
RFID technology in FASTag operates on radio waves to communicate between the tag and the toll plaza RFID reader.
When a vehicle with the tag comes to the toll plaza, the RFID reader there emits radio signals. The RFID tag receives the signal and responds by transmitting its unique identification details, which are linked to the vehicle owner’s prepaid account or bank wallet. The toll system verifies the account and deducts the applicable fee automatically. Once the payment is confirmed, the barrier gate opens, allowing the vehicle to pass through without stopping.
This process reduces congestion at toll plazas and enables faster, cashless travel.
Benefits of RFID in FASTag
The RFID system in FASTag provides several advantages for vehicle owners:
- Time-saving: No need to stop for cash transactions.
- Convenience: Automatic toll deductions linked to your account.
- Transparency: All toll transactions are recorded digitally.
Conclusion
The RFID technology is the backbone of FASTag, enabling cashless, contactless toll transactions across highways in India. Its functionality enhances efficiency, reduces travel delays and simplifies toll management.
